HI, I’m running a Windows Server 2003 Standard Edition R2 with Service Pack 1. It has only one DC running. Don’t know why suddenly my Netlogon stopped working and is not starting anymore. Due to this my entire domain is down. I tried searching web for some help but dint found anything helpful. Hope you guys can help me out with this.

Here is what I found listed in the Event Log:

event log
Application
Userenv ID 1053
Can't determine computer's role (specified user does not exists).

Syetm
Nelogon ID 5602
erro accessinf local computer or network

Directory Service
NTDS General ID 1126
Can't contact the global catalog

DNS
No errors
In my DBS forward lookup zone I see only the A record of my server (and not
the records of the several client)

And here is the netlogon log:

Somebody please help me to get out of this.

Before I could I suggest a proper solution, I must know the proper cause of this problem. So, did you made any changes in the server just before its failure such as Windows Update or such things? Also how did you lose the dc in the first place? Until youi reply these questions, just give this a try.

Open command prompt, enter netdiag /fix. See if running command can repopulate the dns records for your dc. Apart from this also try to run diagnostics against your Active Directory domain. See if it works. Let me know the results with answer for the questions I asked you above.

Thank you very much for your help Oshea. As you suggested, i ran the netdiag and following is the output (only errors)

What now? Please help.

Well, according to your test and results, to me it probably appears as DNS issue. Where is your DNS server located? If the DC is also set as DNS server then just make sure that your DNS server is installed. Also make sure that server NIC primary DNS is pointing to the server itself. Note, DNS must have Domain Forward Zone configured.
