I do not know what this error is but you could double check to verify your domain is healhtly.
Run diagnostics against your Active Directory domain.
If you don't have the support tools installed, install them from your server install disk.
d:\support\tools\setup.exe
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.

I have just built a new Windows 2003 SP2 R2 DC and upon reboot I got the
following error. I have recently seen this error appear on another DC in my
forest again after a reboot. It doesn't appear any other time. Can anyone
suggest what is causing this and how I should resolve the issue.
