From: zealousworks on 3 Oct 2005 11:31 I have an native Windows 2000 Active Directory domain with a number of remote sites, and I am trying to diagnose some Netlogon error messages appearing in the event log of the remote domain controllers: Event Type: Error Event Source: NETLOGON Event Category: None Event ID: 5719 Date: 03/10/2005 Time: 11:08:33 User: N/A Computer: SITE02AD01 Description: No Windows NT or Windows 2000 Domain Controller is available for domain WALKERS.

From: Paul Bergson on 3 Oct 2005 14:19 Has the sysvol share come online and/or is the netlogon service running? Check your event viewer. The second test is just telling you it knows the name of the roles holder, not that it can be contacted. Also try running the full dcdiag test Try running netdiag, repadmin and dcdiag. Look for fail, error and warning errors. Copy the following to a cmd file and run look for error, fail and warn within the reports. Post any errors you can't figure out. make sure you modify DC_Name to the name of a dc in your domain. @echo off c: cd \ cd "program files\support tools" del c:\dcdiag.log dcdiag /e /c /v /s:DC_Name /f:c:\dcdiag.log start c:\dcdiag.log netdiag.exe /v > c:\netdiag.log start c:\netdiag.log repadmin.exe /showrepl dc* /verbose /all /intersite > c:\repl.txt start c:\repl.txt See for more details http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/TechRef/1d4ce93c-54f2-4069-a708-251509c38837.mspx -- Paul Bergson MCT, MCSE, MCSA, CNE, CNA, CCA This posting is provided "AS IS" with no warranties, and confers no rights.

From: zealousworks on 5 Oct 2005 05:46 After lots of investigation, the problem was down to the PDC's network team being set to load-balanced, rather than fault tolerant. Thanks for your reply, as your suggestion did uncover a few other minor mis-configurations.
From: Cary Shultz [A.D. MVP] on 6 Oct 2005 00:16 I will jump in for a second. I always like to install the Support Tools ( from the Service Pack CD-Media vs. the WIN2000 Server CD-Media ) as there are a lot of tools in there (such as netdom and dcdiag ) that are very useful. There are also a lot of other tools out there that useful, such as dnslint, frsdiag,sonar, etc. -- Cary W.
