Netdom for W2K wkst in an NT4 domain

I can not get the NETDOM command to work to re-establish the trust on a W2K workstation in an NT4 domain. This computer was a member of the domain, I placed an old Ghost image on the drive and now I want to re-establish the trust without having to re-add it to the domain and rebooting. I am using the following syntax
netdom member \\ /joindomain
I get the following error.

C:\>netdom member \\ /joindomain
