Discussion:
AD site and services - How do I speed up replication time?

In AD sites and services I have 2 sites, one which is the head office which
has 2 DC's and an offsite site which has 1. I have a good link (100mb) to
this offsite location, it's probably simple and I just want to know how I
can speed up replicate between the offsite and head office DC's?

It's at an hour at the moment.

Try reducing the replication interval to do so please check below key in the
registry

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters

To modify the delay between the change to the Active Directory and first
replication partner notification,
double-click Replicator notify pause after modify (secs). Change the Radix
in the DWORD Editor to Decimal to see the default 300 seconds (5 minutes).
Change it to the number of seconds you desire.

To modify the notification delay between domain controllers,
double-click Replicator notify pause between DSAs (secs). Change the Radix
in the DWORD Editor to Decimal to see and change the default 30 seconds.

Sorry about this but i don't see:

Replicator notify pause after modify (secs)
Replicator notify pause between DSAs (secs)

under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters

Can't this be done via a GUI?

Thanks

Hi Gonzo

To use GUI open Active Directory Sites & Services, under sites container
expand your site then expand server then explore server name select NTDS
Settings. on right pane you will see connections between diffrent sites
select the connection you want to modify right click properties and choose
"Change Schedule"

GUI gives limited choices.

Would you use the registry then? Is there a log file I can check when the
replication happens to see if it works?

The easiest way to do this is

Open up Active Directory Sites and Services
Find the Site Link you want to change the replication schedule and Right
click on it
Select Properties
The field "Replicate Every" is the current interval between sites
If you select the "Change Schedule" you can modify when replication can and
can't take place

I would HIGHLY discourage you from using the registry to make these changes

Is there a log to see what times the replication takes place just to prove
its working?

Run repadmin

repadmin.exe /showrepl dc* /verbose /all /intersite > c:\repl.txt


If you don't have the tools installed, install them from your server install
disk.

If your link is that good, you should just consider using a single site
for both of the locations together. If that isn't satisfactory, the best
you can lower the site link schedule to is 15 minutes. If you want to go
lower you need to enable change notification on the site link (this is a
documented procedure) and then you will get down to times similar to
intrasite replication though it will still all flow through the
bridgehead. If you do this, your compression will be gone on all of that
traffic so between that and the fact that you will be sending change
notification messages over the link your overall link utilization will
increase, probably significantly.
