Re: Disappearing Workstations

Do you mean that the workstation record no longer exists in AD at all? (That would be unusual in my experience.) Or that these
machine accounts are disabled in AD or not working for logon?

My initial suggestions would be to

1) check time synchronization and time zones on the workstations and server
2) look in the server and workstation event logs for any concurrent errors that might suggest a cause
3) Rename the offending computers and explicitly dis-join and re-join them to the domain
4) Run nltest and (if needed) netdom to verify and fix any trust problems with the computer accounts
5) Take delete access off the machine account's AD record so that whatever is trying to delete it will have a hard time

I am assuming you don't have other DCs as replication issues would be another consideration.
