The trust relationship between this workstation and the primary domain failed

This evening I encountered an error while attempting to log onto my Windows 7 client machine: The trust relationship between this workstation and the primary domain failed

I have a Windows Server 2008 R2 domain controller running DHCP, DNS and of course ADDS.

I figured out the issue (although I would have never of suspected it) moments before the error, I was reconfiguring the DNS IP address for a scope against my DHCP server.

Below is the DHCP scope editor for DHCP in Windows Server 2008 R2. This is a fairly old box which I haven't changed that much over 2 or so years and it is used by many devices/machines.

Searching the web didn't really give any firm solutions other than to rejoin to the domain. so I tried that and it worked.

I think it would be a good idea to raise a bug report for this.

Happy new year!
