FsmoCheck

I have three dc's in my 2k3 domain. When I run dcdiag I
get the following error message from two of the three:

Running enterprise tests on : tif_mis01.com
Starting test: Intersite
......................... tif_mis01.com passed
test Intersite
Starting test: FsmoCheck
Warning: DcGetDcName(PDC_REQUIRED) call failed,
error 1355
A Primary Domain Controller could not be located.
The server holding the PDC role is down.
......................... tif_mis01.com failed
test FsmoCheck

However, if I user the dsquery command from one of the
servers reporting the dcdiag error I get:

C:\dsquery server -hasfsmo pdc
"CN=WINSRV,CN=Servers,CN=Default-First-Site-
Name,CN=Sites,CN=Configuration,DC=tif_mis01,DC=com "

Where "WINSRV" is the correct server having the PDC
emulation role.

How can I correct the DCDiag error?

Thanks,
Bob Hess

Open a command prompt on the DC in question and type net
share from the C: prompt. If you do not see IPC$ or
ADMIN$ as default shares you'll have to add them by
typing net share IPC$ <enter> and net share ADMIN$
<enter>. Run dcdiag again.

Alan,
Thank you for your response.

Both the IPC$(Remote IPC) and ADMIN$(Remote Admin) are
present.

What happens when you run the following:

C:\>nltest /dsgetdc:domainName.com
C:\>nltest /dsgetsite

If these don't come back OK, I'd say we're looking at DNS problems - SRV
records are probably missing.

I don't know how the dsquery command works, but FSMO role holders are stored
in specific AD attributes, and thus all DCs should know of them.

The nltest command come with the support tools.

Have you tried pointing this server at a different DNS server? Or have you
rebooted or restarted netlogon?
