The server was working fine all of last week and no one disjoined it from the domain or removed it’s computer account.
What could cause a server to lose its account on the domain? To get it back to working all I did was re-register the computer on the domain.

That is basically what I did which did solve the problem what I'm asking is what on earth caused the problem?
Hi.
> what on earth caused the problem?
Maybe the del-key? Sometimes even admins use it unintentionally ;)
You should setup auditing to enable you to search for computer account deletions. Maybe 2008 server DC has it setup by default already, have a look at the security event log and search for the server name.
