I know that the Server editions of 2000 allow the use of terminal services for remote administration, however I was wondering if iw was possible at all for client workstations [running 2000 Professional] to be managed using terminal services.

No. Win2k pro is not capable or running terminal services. They can only run
the clientside.
There are a lot of third party solutions out there in the market.
Have a look at winvnc which is even free of charge.
