I have recently come across an issue that is happening on 2 of my Windows 2000 servers in the office where for some reason they loose all authentication to the domain. I get the following events appearing in the Event Log:
In the Application I get:
Type: Error
Source: Userenv
Event ID: 1000
User: NT AUTHORITY\SYSTEM
Description: Windows cannot determine the user or computer name. Return value (1722).
In the System Log I get:
Type: Warning
Source: MrxSmb
Event ID: 3034
User: N/A
Description: The redirector was unable to initialize security context or query context attributes.
and:
Type: Warning
Source: w32time
Event ID: 11
User: N/A
Description: The NTP server \\tmsrv-dc1.law-desk.com didn't respond
I am still looking in to these errors and warnings, as at present we have to restart the servers in the morning to get them operational, but then 24 hrs or so from when the first error and warnings were logged they start happening again. So it narrows it down to something running on those 2 servers.
All the Events point to a DNS issue so I have looked at DNS but it looks ok, just on a glance with a quick look at one of my DC's the next thing to do is run a dcdiag and netdiag I guess to see if DNS and the domain is functioning with no problems.
In the mean time watch this space.
I hope to have an answer soon.
I have tried several things already including removing the servers from the Domain, deleting the computer accounts in AD and then re-joining the domain. but that did not work.
