RPC service unavailable?

The drafter in our department shares his plotter out on the network. Not
the most elegant means of making the device available to all I admit but it
works... or did until recently. After I patched our PCs and activated the
Windows XP firewall, AutoCAD 2000 now tells me it can't connect to the
plotter because "RPC service is unavailable". However, an examination of
services shows RPC is indeed running, so I'm suspecting the patch may be the
culprit.

Anyone have any ideas (besides putting the plotter on a print server)? I
searched but didn't find any examples of anyone else encountering this.

Thanks,

I understand that. I support a lot of people in the Microsoft newsgroups.
But I've seen the occasional employee post there and here so anything's
possible. In addition, there's always the chance one of my peers may know
the answer, just as I've helped other AutoCAD users in the past.
