Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can use this:

but you will need to set it on all computers, and it will remove ALL workgroups from showing up.

I don't believe it is possible to have only the workgroup the PC is a part of to show up like that.  It's either an all or nothing thing.  That's something that is accomplished using multiple domains.
