Computer not showing in Active Directory after Local Update

Posted on 2011-02-22

I have a server running Server 2003 R2 Standard for domain and has a local PC that is running XP Pro.  Last night the PC performed automatic Windows updates and rebooted.  This morning the user was unable to log in and had the error:  "Windows cannot connect to the domain because the domain controller is not available or because your user account is not valid."

The user account is fine.  User was able to log on to another computer with no problem.

I checked the server under active directory and the computer name was missing.  I manually added back in, but it is not giving it a DNS name, or finding the PC's OS etc.  I can ping the computer name from the server and it tests fine.

Any thoughts?

Did you try moving the PC to a workgroup and then adding it back to the domain (not sure if that is what you did by manually adding it)

Thanks

Agree with Mike, delete the PC entry in AD, change to workgroup reboot, change to domain, reboot and it should be within AD again.

Before doing, just check the PC clock is set correctly with the DC time.. this will be handled automatically once joined but just check at joining its synced.

I had tried manually adding a "new" computer in AD.   This worked.  Many thanks!

Sorry, I meant your suggestions worked, not what I had tried.  :)
