I have 2 Server 2003 Domain Controllers and both are also DNS servers. DC1 seems to reboot itself in the late afternoon for no apparent reason and when it's in the reboot process I get errors with mahcines not able to authenticate so I'm thinking that DC2 is for some reason not accepting these authentications. Just prior to the last Reboot I see Event ID 5774 in the System Log.
I located this KB article: http://support.microsoft.com/kb/284963 that suggests that this means The DNS server is not listed in the advancd TCP/IP settings box. However on both DCs the DNS servers are both listed in the advanced section of the TCP/IP settings.
Running DCDiag gives me a 9 page log file. I'm goign to use my judgement and not past that all here. The first thing I see in the log though states that the clock difference between the home server and target server is grater than one minute"This may cause Kerberos authentication failures. ...
Could this be the root of the issue?
Also, there is a third DC that I added because this secondary was not working. I don't need the third I just want to get the secondary working. How do I remove the third so the others stop trying to replicate to it?
