workstation service failed to start

The workstations service (and of course all the other services which depend on this) failed to start on my NT 4.0 workstation. I checked the event viewer and it says that the current domain is not a valid domain or workgroup name.   Right before this problem appeared I know the PDC was rebooted due to logon problems of some sort.  I can logon to the domain from a different workstation, suggesting the domain name is valid.  I went in to control\panel\services and made sure that the workstation was set to automatic.  If the computer account was lost on the PDC from the reboot, could this account for the fact that the domain name is not being recognized.

thanks in advance

Of course yes, if you don't have a computer account in the domain you can't login so that's probably why your Wks Service won't run.
Check with your domain admin if your account is still available.
Ask if if he has delted it and recreated it, 'cause this could be a problem too.
In such case, the best to do is the following :
- Delete your account on PDC
- Start Wkstation in local mode ( using the Wks name as Domain )
- Logon on the Wks with Local Administrator rights
- Goto Network Control Panel
- In Identification select change and rewrite the Domain name, and select "create Account on PDC" ( you must know a Name and password of a Domain Administrator to do that )

Hope it help, if not give me more infos.

Looking at the services which depend on the workstation service indicates that the domain name is already in use by another computer on the network.  I don't understand this.  Of course the domain name is in use by other machines on the network.

That's because of several things :
When you create an account for one computer onthe network, this computer receives a unique SID ( Unique number )when you delete and recreate the computer name, another new SID is given. This is a unique number. The PDC keeps the old SID number so it is able to identifie the old computer if it has been removed by mistake. Try to delete another time this name and recreate an new account with a new computer name. There is some way that your Network Administrator should be aware of to remove old unused SID registrations.
In some case those SID are only kept during a small period of time so it might be solved without interventions.
