So you can't just do the standard NetServerEnum RAP call on it?

Was this the thing that Richard said only responded to 137 though?

Well, the URL for addressing a workgroup would not change. It would just
be like smb://name. The code would just have to query the NAME<0x20>,
NAME<0x1D>, and now NAME<0x1B> all in parallel. Actually this might be
as easy as just switchingg the 0x1D for 0x1B. Talk about a one-liner,
how about 1 character -- wouldn't that be embarrassing :~P
