I have a computer at work that belonged to a different domain and when I try to join it to our domain the option is grayed out and a message says, "The identification of the computer cannot change because the workstation servise is not running. Open the services snap-in to insure it is running ans set its startup type as "automatic". When I try to do this I get a message that "Windows could not start the workstation service. The system cannot find the file specified."
Do you know how to proceed?
