can’t join domain, net logon won’t start

I have a Win2k (SP2) server not in a domain. When I try to join it to a domain, I get an error – “The executable program that this service is configured to run in does not implement the service” – looking in the event viewer, the error is caused because the net logon service can’t start. When I look up the error code, it says it can’t start because the server is not part of a domain. I have reinstalled IP but was no help. Any ideas how to get around this so I can join it to the domain. Thanks.
