Problem locating GC server

[Guest]

I'm knee deep in trouble - my BDC failed along with my PDC. The PDC is the
most recoverable out of the two. The output from DCDIAG on the PDC is as
follows:

Starting test: Intersite
......................... passed test Intersite
Starting test: FsmoCheck
Warning: DcGetDcName(GC_SERVER_REQUIRED) call failed, error 1355
A Global Catalog Server could not be located - All GC's are down.
Warning: DcGetDcName(TIME_SERVER) call failed, error 1355
A Time Server could not be located.
The server holding the PDC role is down.
Warning: DcGetDcName(GOOD_TIME_SERVER_PREFERRED) call failed, error
135
5
A Good Time Server could not be located.
Warning: DcGetDcName(KDC_REQUIRED) call failed, error 1355
A KDC could not be located - All the KDCs are down.

Searching the microsoft KB hasn't seemed to turn up any useful articles on
how to fix this. I checked both DNS and WINS and they both seem to be running
fine. Does anyone out there have any insights into what causes these errors
and how to fix them?

You can try the following:

1. Check that the KDC service is actually started on the PDCe.
2. Remove the GC functionality from the PDCe and then reenable it as a
GC. You will see an 1120 event in the DS event log when the GC stops
advertising, then an 1119 event when it advertises again.
3. Check to determine whether SYSVOL is shared (run 'net share' from
command line). If it is not, look into the following options for
troubleshooting:

This may require an auth restore of FRS.

4. Run 'netdom query fsmo' to determine who the DCs think the FSMO
role-holders are and correct any problems there.
