I have 5 servers and over 60 workstations on my network....2 days ago 5
machines could not access resources from 1 server...all 5 workstations had
the same messages in their error logs....see below. None of the servers
showed any errors. I have checked the the net and links below with no
solutions. Thanks in advance.

The computer account may have been deleted, renamed or reset. Remove the PCS from the domain and re-add them again to fix it.

My first port of call here would be to check the DNS settings on the server and clients to make sure they are pointing to the authoritative server for the domain.
If this is correct then the problem may be with the network card drivers on the server. try updating the driver.
Windows can sometimes unbind protocols from adapters if it thinks the link state is not 'up' which would cause the symptoms you describe, you can prevent this by disabling media sense on the tcp/ip protocol (see http://support.microsoft.com/kb/239924)

Hope this helps and good luck.

Hi

Also check your hardware. We use two switches, one of which is used just for three machines - all three machines could not connect to the network - the switch needed to be turned off then turned on again.

Good luck

I have seen antivirus software on the server cause this problem.

Stop your antivirus services on your server and see if that resolves the issue. It is does, check with your av provider for a patch.

Do these workstations have gigabit ethernet cards ? Are they connected to a switch or a hub ?
what are the brand PC's, NIC cards and type of switc/hub ? Some Gig NIC cards have trouble when connected to a switch, particularly a problem when the switch has spanning tree protocol enabled. This trouble can start with the NIC causing the switch to delay making the port available in time for windows to recognize that it is connected to a network thus the errors. Answer my questions, and I may be able to give you more specific info regarding your problem

I would agree with p.j.hutchison's suggestion. It appears that the computer accounts have been deleted from AD. To fix it I would would remove the computer from Active Directory by joining them to a workgroup. Then look in AD Users and Computers and make sure the computers do not appear in there any longer. Then rejoin them to the domain and this will create new accounts and should connect without any problems.
