Hello, I have the problem with the following message:
Loading Image...

I’m running Windows Server 2008 and want to use it as a RADIUS server to
authenticate WiFi users.
It works that way:
- I have DSL modem, connected to the PC via USB port;
- my PC works as an internet gateway (ICS) and thus has IP address:
192.168.0.1 (Internet connection with local DNS address and a forwarder set
on the DNS server).
- I have Linksys WRT-160N router working as an Access Point.
PC is running Active Directory service (with integrated DNS role), DHCP, NPS
(without Routing and Remote Access) and certificate services.
Now there’s a problem whenever I try to set a RADIUS for wireless users
(doesn’t matter if it’s separate user group or existing one) – I get the same
message as presented on the screenshot.
Below is the output from DCDIAG /test:DNS:

Everything else is working fine. I really don’t know what’s wrong.

especially starting tomorrow).

Hello marek1712,

Do you use IPv6, then disable it:
http://www.microsoft.com/technet/network/ipv6/ipv6faq.mspx

Also check the above link if you have 2003 DNS servers and reverse lookup
zones.

After that run netdiag /fix.

If you need IPv6 check this:
http://technet.microsoft.com/en-us/library/cc738372.aspx

http://download.microsoft.com/download/1/2/4/124331bf-7970-4315-ad18-0c3948bdd2c4/IPv6Trans.doc

http://download.microsoft.com/download/e/9/b/e9bd20d3-cc8d-4162-aa60-3aa3abc2b2e9/IPv6.doc

For whatever reason i also read a posting that uninstalling Symantec AV from
a DC solved this error.

Hello and thank you for quick answer.

I am home user of the MSDN AA version. Therefore I don't need IPv6.
I wasn't sure if I can disable it. Now I'm certain. As soon as I get back
home - I'll disable it (as shown in the link you provided).
My PC is the only one server, with 2008 functional level. I've set up
reverse lookup zone but I'm not really certain if it's required for a few
computers.

As for antivirus - I've used KIS2009, but switched to the trial version of
the Avira Server.

Thanks again. I'll post an update later.

Best regards,
Marek

I did as you told me (except for the "netdiag" part - I had to use "dcdiag
/fix"). That error still appears but at least I don't see AAAA warnings.

Hello marek1712,

Multihoming a Domain controller, what you did here, is a not recommended
configuration and should be avoided. It results in problems exactly you have.
Remove the multihoming and use only the domain internal ip addressing on
the DC.

Hello Marek,

I must fully agree with Meinolf. You do not want to multihome a DC. This is
what's causing the domain not found error. If I may recommend, Remove the
PPPoE configuration, disable ICS, and purchase an inexpensive Linksys router
(USD $80.00) to perform this function. Make sure you only use the internal
IP of your DNS server in all clients and the DC. After that, you should be
error free.

Well, I made a mistake buying Linksys WRT160N (I need WAG160N). As USD is
quite expensive right now, I wanted to wait a little while for it to get
cheaper.
But as you suggest - I'll borrow a router from my friend (WAG200G) and test
it out. As always - I'll provide feedback after that.

I've removed my modem and all traces of the PPPoE connections.
After connecting WAG200G (DHCP disabled, gateway's address: 192.168.0.3) and
setting forwarder to 192.168.0.3 (while keeping server's .0.1) I've made some
tests.
DCDIAG shows no errors, nslookup works flawlessly.
I've forgotten about one thing. After seeing that message about contacting
domain I am able to add user group by selecting it from the list for the
second time. I'm 99.9% sure it won't work though.

Is the server listed correct in DNS without any other ip additional addresses?
Check all zones for that.

Did you disable ICS? A note on that - ICS and DHCP/DNS services conflict
due to the way ICS works. If not disabled, please do so. An ipconfig /all
after the changes, as Meinolf requested, would be helpful to confirm the new
changes.

When you remove connection, that has been shared via ICS, ICS is disabled
automatically (at least I think so).
There's still a questions - how can I share my connection with other devices
(it has to go through my PC)? Via RRaS (NAT function to be precise)?
BTW - I'd like to know what multihoming is and why DHCP + ICS in not a good
idea. Can I find it on Technet or should I rather search some MS Press books?

@Meinolf Weber [MVP-DS]
There were some entries with public IP, but I've removed them all.

Still - it doesn't work. I had to return the router, so I've tried it
without any internet connection. In a day or two I should get my own router
so I'll be able to do more thorough tests.

It is better to use the Linksys router. To share a connection using NAT,
which can be done, requires minimum or two NICs, which is called
multihoming. Multihoming means the machine has more than one interface
(NICs, PPPoE, RRAS, dialup, etc). Multhoming is not recommended on a domain
controller due to the entries it registers into DNS. AD is Site aware. Sites
are based on IP subnets. A multihomed DC has two IPs, and registers both,
however a DC CANNOT be part of two Sites. If you define both as part of the
one Site, then AD will think it has two DCs on that site with the same name,
causing problems. Also, the GC record gets registered with both IPs, whici
causes problems when a client gets the IP of the outside NIC and cannot
communicate to it, therefore it fails to logon, etc. The LdapIpAddress gets
registered twice, which is used for DFS and GPOs. If the client gets the
outside NIC, neither will work and generate errors.

To properly make a multihomed DC work properly requires quite a number of
configuraiton changes including registry changes to alter a DC's default
settings to force it to work. I will post the complete step by step for you
in a separate reply for you to review, read and study carefully if you would
like to attempt the tasks required if you would like to keep the DC
multihomed.
Post by marek1712
BTW - I'd like to know what multihoming is and why DHCP + ICS in not
a good idea. Can I find it on Technet or should I rather search some
MS Press books?
ICS is a mini NAT service that allows to share the outside NIC with internal
machines. ICS sets up it's own mini version of NAT, DNS proxying, and DHCP,
none of which can be controlled or configured esily without registry
changes. It also sets up the machine as a DNS proxy, and not a DNS server
itself, proxying the DNS requests to the outside interface's DNS address.
Therefore if you install DHCP on the same server as ICS, the two will
conflict, as well as if DNS is installed, Matter of fact you will get 11196
(trying to rememer the event ID#) in the event logs which clearly indicates
the conflict.

It's a DC. To make sure a DC works propertly to perform it;s function as a
domain controller, configure it within recommended guidelines, and do not
multhome it, nor use ICS.

Still - it doesn't work. I had to return the router, so I've tried it
without any internet connection. In a day or two I should get my own
router so I'll be able to do more thorough tests.

Marek,

The following is my blog on multihoming. Please read to gain a better
understanding of what it is, and what it causes on a DC.

Multihomed DCs, DNS, RRAS servers.
By Ace Fekay, Directory Services MVP
==============================================


Multihomed DCs WILL cause numerous issues. It's highly recommended to single
home all DCs and use a non-DC for the multihoming purposes. If it is the
internet gateway, it is recommended to purchase an inexpensive, or cable/DLS
router, or even better, a Cisco or similar firewall to perform the task.
This will protect a Windows machine from internet exposure and possible
compromise, which if compromised by an internet attacker remotely, can
further compromise the rest of the internal network.

Also if attempting to use ICS on a DC, this further complicates matters with
DC functionality, and cannot be fixed with the following steps outlined in
this article.

To explain why will require a little background on AD and DNS:

First, just to get this out of the way, if you have your ISP's DNS addresses
in your IP configuration (DCs and clients), they need to be REMOVED. If the
ISP's DNS is in there, this will cause additional problems. I usually see
errors (GPOs not working, can't find the domain, RPC issues, etc), when the
ISP's DNS servers are listed on a client, DCs and/or member servers, or with
multihomed DCs. If you have an ISP's (or some other outside DNS server or
even using your router as a DNS server) DNS addresses in your IP
configuration (all DCs, member servers and clients), they need to be REMOVED
and ONLY use the internal DNS server(s). This can be very problematic.

Basically, AD requires DNS. DNS stores AD's resource and service locations
in the form of SRV records, hence how everything that is part of the domain
will find resources in the domain. If the ISP's DNS is configured in the any
of the internal AD member machines' IP properties, (including all client
machines and DCs), the machines will be asking the ISP's DNS 'where is the
domain controller for my domain?", whenever it needs to perform a function,
(such as a logon request, replication request, querying and applying GPOs,
etc). Unfortunately, the ISP's DNS does not have that info and they reply
with an "I dunno know", and things just fail. Unfortunately, the ISP's (or
your router as a DNS server) DNS doesn't have information or records about
your internal private AD domain, and they shouldn't have that sort of
information.

Also, AD registers certain records in DNS in the form of SRV records that
signify AD's resource and service locations. When there are multiple NICs,
each NIC registers. IF a client, or another DC queries DNS for this DC, it
may get the wrong record. One factor controlling this is Round Robin. If a
DC or client on another subnet that the DC is not configured on queries for
it, Round Robin will kick in offering one or the other. If the wrong one
gets offered, it may not have a route to it. On the other hand, Subnetmask
Priortization will ensure a querying client will get an IP that corresponds
to the subnet it's on, which will work. To insure everything works, stick
with one NIC.

Since this DC is multi-homed, it requires additional configuration to
prevent the public interface addresses from being registered in DNS. This
creates a problem for internal clients locating AD to authenticate and find
other services and resources such as the Global Catalog, file sharing and
the SYSVOL DFS share and can cause GPO errors with Userenv 1000 events to be
logged, authenticating to shares and printers, logging on takes forever,
among numerous other issues.

But if you like, there are some registry changes to eliminate the
registration of the external NIC or simply use the internal networking
routing to allow access. Here's the whole list of manual steps to follow.

Another problem is the DC now becomes part of two Sites. This is another
issue that can be problematic.

But believe me, it's much easier to just get a separate NAT device or
multihome a non-DC then having to alter the DC. If the both NICs are
internal, I would suggest to pick a subnet, team the NICs and allow your
internal routers handle the traffic between subnets - Good luck!

1. Insure that all the NICS only point to your internal DNS server(s) only
and none others, such as your ISP’s DNS servers’ IP addresses.

2. In Network & Dialup properties, Advanced Menu item, Advanced Settings,
move the internal NIC (the network that AD is on) to the top of the binding
order (top of the list).

3. Disable the ability for the outer NIC to register. The procedure, as
mentioned, involves identifying the outer NIC’s GUID number. This link will
show you how:
246804 - How to Enable-Disable Windows 2000 Dynamic DNS Registrations (per
NIC too):
http://support.microsoft.com/?id=246804

4. Disable NetBIOS on the outside NIC. That is performed by choosing to
disable NetBIOS in IP Properties, Advanced, and you will find that under the
“WINS” tab. You may want to look at step #3 in the article to show you how
to disable NetBIOS on the RRAS interfaces if this is a RRAS server.
296379 - How to Disable NetBIOS on an Incoming Remote Access Interface
[Registry Entry]:
http://support.microsoft.com/?id=296379

Note: A standard Windows service, called the “Browser service”, provides the
list of machines, workgroup and domain names that you see in “My Network
Places” (or the legacy term “Network Neighborhood”). The Browser service
relies on the NetBIOS service. One major requirement of NetBIOS service is a
machine can only have one name to one IP address. It’s sort of a
fingerprint. You can’t have two brothers named Darrell. A multihomed machine
will cause duplicate name errors on itself because Windows sees itself with
the same name in the Browse List (My Network Places), but with different
IPs. You can only have one, hence the error generated.

5. Disable the “File and Print Service” and disable the “MS Client Service”
on the outer NIC. That is done in NIC properties by unchecking the
respective service under the general properties page. If you need these
services on the outside NIC (which is unlikely), which allow other machines
to connect to your machine for accessing resource on your machine (shared
folders, printers, etc.), then you will probably need to keep them enabled.

6. Uncheck “Register this connection” under IP properties, Advanced
settings, “DNS” tab.

7. Delete the outer NIC IP address, disable Netlogon registration, and
manually create the required records

a. In DNS under the zone name, (your DNS domain name), delete the outer
NIC’s IP references for the “LdapIpAddress”. If this is a GC, you will need
to delete the GC IP record as well (the “GcIpAddress”). To do that, in the
DNS console, under the zone name, you will see the _msdcs folder.

Under that, you will see the _gc folder. To the right, you will see the IP
address referencing the GC address. That is called the GcIpAddress. Delete
the IP addresses referencing the outer NIC.
i. To stop these two records from registering that information,
use the steps provided in the links below:
Private Network Interfaces on a Domain Controller Are Registered in DNS
http://support.microsoft.com/?id=295328

ii. The one section of the article that disables these records is
done with this registry entry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters
(Create this Multi-String Value under it):
Registry value: DnsAvoidRegisterRecords
Data type: REG_MULTI_SZ
Values: LdapIpAddress
GcIpAddress

iii. Here is more information on these and other Netlogon Service records:
Restrict the DNS SRV resource records updated by the Netlogon service
[including GC]:
http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechnol/windowsserver2003/proddocs/standard/sag_dns_pro_no_rr_in_ad.asp

b. Then you will need to manually create these two records in DNS with
the IP addresses that you need for the DC. To create the LdapIpAddress,
create a new host under the domain, but leave the “hostname” field blank,
and provide the internal IP of the DC, which results in a record that looks
like:
(same as parent) A 192.168.5.200 (192.168.5.200 is used for illustrative
purposes)

i. You need to also manually create the GcIpAddress as well, if
this is a GC. That would be under the _msdcs._gc SRV record under the zone.
It is created in the same fashion as the LdapIpAddress mentioned above.

8. In the DNS console, right click the server name, choose properties, then
under the “Interfaces” tab, force it only to listen to the internal NIC’s IP
address, and not the IP address of the outer NIC.

9. Since this is also a DNS server, the IPs from all NICs will register,
even if you tell it not to in the NIC properties. See this to show you how
to stop that behavior (this procedure is for Windows 2000, but will also
work for Windows 2003):
275554 - The Host's A Record Is Registered in DNS After You Choose Not to
Register the Connection's Address:
http://support.microsoft.com/?id=275554

10. If you haven't done so, configure a forwarder. You can use 4.2.2.2 if
not sure which DNS to forward to until you've got the DNS address of your
ISP.
How to set a forwarder? Good question. Depending on your operating
system,choose one of the following articles:

300202 - HOW TO: Configure DNS for Internet Access in Windows 2000

I have bought my own router (Linksys WAG160N), did what you told me
and that problem still exists.
Apprently something else is going on that is preventing you from opening
ADUC.

Have you confirmed that RRAS, ICS, NAT, uninstall the PPPeE software, and
everything else that was implemented prior to this are all disabled?

Please run and/or post the following:
1. net start > c\netstart.txt (please post what is in the text file)
2. dcdiag /v /fix > c:\dcdiag.txt (please post what is in the text file)
3. netdiag /v /fix > c:\netdiag.txt (please post what is in the text file)
4. Re-run a new ipconfig /all for us.
5. Any event log errors (in any of the logs)?
6. When you look in DNS, do you see any IP addresses other than the current
IP address thsi machine is set to? If so, please delete them. This includes
the LdapIpAddres, which is the one that shows up as "(same as parent)" name.
The only IP that shows up for this is the current IP. Same with the hostname
record. Also check the _gc folder under _msdcs. There should only be one IP
address.

Good to hear something changed! :-)

As for the group issue, it should work from the default location, which is
your domain. What functional level is the domain and forest in?

Stupid me - I didn't know there's second page of replies (figured just know

Anyway - there aren't any (visible) problems with the ADUC. As you can see
there's only a problem which lies elsewhere.
My domain is on the 2008 functional level.
As for HOSTS and LMHOSTS, these files contain only default entries:

- LMHOSTS is commented out

And thank you for the article on the multihoming. I'm going to read it right

Hello marek1712,

Nice to hear that something changed, but still you should be able to add
domain groups also. Did you try with a self created group instead of using
domain users?

Also as Ace requested earlier an ouptut from the different commands would
be fine.

Best regards

I've checked all the records in the DNS and there are no problematic entries.
I don't have netdiag (I've installed Win2k3 Resource Kit, but it isn't there
also, as (I think) it's a native tool for Windows 2003 and older).
As for net start... there may be language problem. I'm using English version
of Windows with Polish MUI package. I've changed my lang. back to English,
but all the service names are in Polish. If you really need it - I can
translate it to English but it will take a few moments.

Event Viewer: aside from some random applications (3rd party, not related to
the AD) crash logs, there's nothing special. Only this:

Hello marek1712,
Nice to hear that something changed, but still you should be able to add
domain groups also. Did you try with a self created group instead of using
domain users?
Also as Ace requested earlier an ouptut from the different commands would
be fine.
Best regards

Hello marek1712,

Your server is 2008 R2 or WIN7 the beta version from 2008, is this correct?

If the above one is wrong you can copy the netdiag.exe from the installed
support tools from 2003 to the 2008 machine. Netdiag does not work with 2008
R2, as far as my tests go now.

Best regards

Hello marek1712,

I asked about the WIN7 because my dcdiag on 2008 looks different then yours
and exactly the same on my WIN7 test machine.

As you can see the netdiag states DNS problems, are you able to open the
file with notepad and check the content? Please post it here.

Best regards

Is your server the x86 or x64 version?

@Meinolf - it may be the tool's problem. Besides - the file exist and
Administrators/SYSTEM have full control of it.

@Ace - It is x64 version. I've read that 32-bit version of netdiag may
display exactly the same errors if you use it on x64 systems. Unfortunately I
don't have 64bit executable.

Ok, let's regroup. This thread has gotten pretty long and instead of trying
to read back, let me ask. How many DCs do you have currently? Based on the
errors I saw in the dcdiag, it looks like it is trying to replicate with
another DC.

Latency information for 2 entries in the vector were ignored.
2 were retired Invocations. 0 were either: read-only
replicas and are not verifiably latent, or dc's no longer replicating this
nc. 0 had no latency information (Win2K DC).
DC=DomainDnsZones,DC=przyklad,DC=pl


Run the following, and please post. Also, do you use WINS?

netstat -c
repadmin /showrepl

Under Sites Services, how many DCs show up under your site or any other
sites?

I do not use WINS.
This computer is my only server (my personal computer to be precise).
There is only one server in "Sites and Services" (in
"Default-First-Site-Name").

"Netstat -c" doesn't work (there isn't such switch. Did you mean -f?).
REPADMIN output:

It looks fine, but just in case, let's rename it along with the netlogon.bak
file to old1 and .old2.
As soon as you do that, go to a command prompt:

ipconfig /registerdnd
net stop netlogon
net start netlogon

And it will generate a new one and populate DNS with the updated info.

Also, concerning the the net start, and I understand it is in Polish, so
maybe you can look for the following services in Server Manager to make sure
they are enabled or disabled:

I'm sorry I couldn't reply faster (I had an important exam today).
I have disabled IPv6 in the NIC's properties (and the registry). Is it
really required to disable Link Layer items?
I have installed Avira Server trial as KIS2009 isn't supported by the
Windows Server.
What should I disable in the Windows Firewall (it's running by the way)?
ADUC is working properly. This problem occurs only when I try to add a group
to the RADIUS rule in the Network Policy Server.

To add a user I open ADUC, click on the "Create new user..." button, fill
the information (e.g. user logon name: test2 and pick @przyklad.pl as it's
naturally the only option available), then click on next (filling password)
and finish at the confirmation window.
To create a user group I click similar button, fill-in group's name , select
Global group scope and "Security" as a group type.
To add a user I pick "Properties" of a given group, select "Members" tab and
select users via "Add..." button.

As for the services - everything has the status as shown by you.

Hello marek1712,

In 2008 the firewall is running by default, according to the roles and features
you install the needed ports are opened automatic. I am running out of ideas
why it is not possible, to be honest. The domain and DNS seems to be ok.
Maybe you should think about to open a call at MS support.

If the only concern is when adding the group in NAP, maybe NAP is not
configured properly or it is looking for a Universal Group.

Otherwise at this point, if that doesn't work, and I don't know what you
went through to configure NAP and RRAS (which is a whole other procedure and
process for a separate discussion to go over), maybe I must agree with
Meinolf that it may be time to call Microsoft PSS and open a ticket.

Well - I did everything by default. I didn't install RRAS as I don't need
Health Policies and such - only 802.1X authenticating based on certificates.

Anyway - I don't see a need to pay lots of money to MS support if the only
problem is to switch to another container when selecting user group in the
NPS.

I'd like to express my gratitude to all the help both of you provided. As a
beginner I didn't know of certain issues and you certainly helped me get rid
of them. Once again - thank you and best regards,

Hello Marek,

Glad to be of service, for the most part. Keep learning. There's alot to
learn, and after all the years I've been doing and teaching it, I still find
stuff I didn't know about!

I'm sorry, I was trying to read back in the thread to see where it is now
failing. The ipconfigs look good, but it appears the dcdiag is spitting out
errors regarding Kerberos, not able to get a DC list, among others.

I apologize if we went over this, but if you can provide a re-cap on the
following to get us caught up, that would be great.

Have you disabled the IPv6 services in the NIC properties? (Disable IPv6,
and the two Link Layer objects).
Any 3rd party antivirus or spyware programs?
Are all 3 instances of the Windows Firewall disabled?

And describe how you are trying to add a group or a member to the group.

Thanks
Ace
