Strange win 2k error - failure to logon.

[Domino]

Hey guys,

 

I don't know if anyone has come across something similar, but we've got a strange issue here.

 

One of our computer rooms (running win 2000 sp4) has suddenly decided its not gonna let anyone log onto the (2003) domain, it brings up a 'network unavailable' message. And just that room. everywhere else is fine.

 

If you log in as a local admin you can get in, then log on to the network and browse/connect to servers/etc. they're also still getting their IPs via DHCP and have everything setup properly from that viewpoint.

 

Everything looks fine in the OU they're in, and taking them out produces no difference. The server hasn't tombstoned tha accounts or anything, they're all still active.

 

As far as I/we can tell, nothing has changed. Everything looks as it has always been, yet all of a sudden they refuse to work. I even re-ghosted from a 6-month old image to no avail.

 

The event log has a few errors in, mostly saying the domain controller could not be contacted...but i can see no reason for this

 

I'm stumped really....

Sounds like a DNS problem.

my first thoughts - yet theres nothing been changed.

 

Its just started happening yesterday afternoon.

 

Any idea on what I should be checking for - cause to myself it all looks fine
