Workstations "kicked Off" Domain

[genistas]

Hi,

Thanks in advance for your help.

 

We've got a Server 2008 R2 of approximately 500 computers. Within that last couple of days, we've had several computers get randomly "kicked off" the domain. When a user attempts to log in, in gives an error that the domain controller cannot be found or that there is no account for that computer. However, when I go into active directory, the computer's account is still there.

 

The fix is to log in locally to that machine, goto network identification and retype the domain name. After a restart the computer is again able to log onto the domain.

 

The fix is easy enough but every day brings another batch of machines that can't connect until I readd them. Any ideas what could be going on? Thanks!

This sounds like a problem with the secure channel not working properly. Things to check are system time synchronization between the affected machines and the DCs, DNS, and AD replication.
