Windows cannot connect to domain


Last week one of the computers (XP Pro) started refusing connecting to the server (SBS2k8) - the user logged on, and immediately they were logged off. Everything was fine the day before. So the user changed the password, they tried different user accounts but the same still happened.
This morning I was called in to have a look. I have disabled and reenabled the computer in AD and since doing that I get a message: Windows cannot connect to the domain because domain controller is down....
I have also tried using domain admin account to log in, same message. I was thinking of removing this PC from the domain by logging in through local account but noone knows the password for the local account.
What are options do we have?

Try using an offline password change to restore local admin password. Google will provide you a lot of them. Usually are a bootable CD or floppy.
When you can logon on workstation, check dns configuration, remove from domain and delete machine account and rejoin again.

Good luck
You need to take the computer back to a workgroup, then add it back to the domain - use the tool at to reset the local password. I have used it successfully in the past

OK, I'm in the software now to reset the admin account password but none of the accounts is marked as admin. There is an account named: DiasbledAdmin so I've reset that one and then tried to log in to it locally but the sytem says that account is Disabled.
So, is there a way to enable that account it without getting into Windows? Or changing any of the accounts to an admin account?

Because none of the recommendation by experts didn't help due the computers condition. Thanks for help.
