Ok, let's start again on another way. Is the "dead" DC1 restored from a backup
or image or still not existing? Please run diagnostics like Paul described
If you don't have the support tools installed, install them from your server
Run dcdiag, netdiag and repadmin in verbose mode.
-> DCDIAG /V /C /D /E /s:yourdcname > c:\dcdiag.log
-> netdiag.exe /v > c:\netdiag.log (On each dc)
-> repadmin.exe /showrepl dc* /verbose /all /intersite > c:\repl.txt
-> dnslint /ad /s "ip address of your dc"
**Note: Using the /E switch in dcdiag will run diagnostics against ALL dc's
in the forest. If you have significant numbers of DC's this test could generate
significant detail and take a long time. You also want to take into account
slow links to dc's will also add to the testing time.
If you download a gui script I wrote it should be simple to set and run (DCDiag
and NetDiag). It also has the option to run individual tests without having
to learn all the switch options. The details will be output in notepad text
files that pop up automagically.
The script is located on my website at http://www.pbbergs.com/windows/downloads.htm
Just select both dcdiag and netdiag make sure verbose is set. (Leave the
default settings for dcdiag as set when selected)
When complete search for fail, error and warning messages.

Did you check that it was replicated over all DC's? Do you have any
DC as Global catalog available? Also in a single forest domain you
should make all DC's GC.
This rabbit hole just gets deaper...
Let me establish a glossary: DC1 is the dead DC, and it's been dead
for 4 months.
DC2 is the other DC in the same domain as DC1 and the one that's
seize roles. There are two other DCs (DC3 and DC4) in a subdomain.
are all the DCs in my entire forest.
DC1 and DC4 are GCs (and of course DC1 is now dead). So I set DC2 as
a GC server
but noticed that that fact didn't replicate to DC3 and DC4 so I
attempted to force
replication (using "Replicate now" in the Sites and Servers MMC).
the fact that the tombstone lifetime has expired and now they won't
I would gladly ignore that fact for now, but I still don't know if
it's affecting my
ability to seize the Schema Master role on DC2 (which still gives the
that started this thread). The user acct I'm using is in every Admin
can find (Domain Admin, Enterprise Admin, Schema Admin...).
I must be missing something!
