NetServerEnum2 from libsmbclient on port 445.

[Christopher R. Hertel]

Hmmm, yeah...

This is an interesting area of study.  The NetServerEnum2() function
call is supposed to return a list of NetBIOS names.  SMB on port 445
is NetBIOS-less SMB.  In theory, it makes some sort of sense that a
NetServerEnum2() call via port 445 would not return any NetBIOS server
names.

My gut, though, is that the LMB was recently elected and had not had
time to rebuild the Browse List.  Can you verify that for me (one way
or the other)?
