[pptp-server] Net Neighborhood is misbehavin'

[Robert Dege]

Okay, after rigorous testing, I believe that I am ready to post my 
question to the listserv with as much detail that I can provide.
This is a slightly long read, so go grab yerself a cup of coffee.

Problem: PPTP Client can't browse Network Neighborhood

Some History on Network
=======================
1 - Using a Class B Network (172.28.x.x)
2 - Network consists of Win95/98/NT 4.0, Linux, Alphas, etc.
3 - No WINS, No DC, everything is Peer-to-Peer
4 - Novell issues DHCP to standard clients, and have NDS File server
5 - I have the PPTP Server setup as a WINS server (smb.conf pasted below).
6 - PPTP client is Win98 & Linux on a laptop.

What works
==========
1 - PPTP Works.  I can ping, telnet, http://, ftp ANY machine.
2 - When I double-click on Entire Network, I am able to see all the 
workgroups within the network.
3 - If I logon to Novell Client, I can successfully access any aspect of 
the Novell tree in Network Neighborhood (no problems detected thus far).
4 - If I do Find Computer, I am able to find a "few" computers.


What doesn't work
=================
1 - When I double click on ANY workgroup in "Entire Network", I get 
\\Workgroup inaccessible.
2 - Almost 80% of the computers I try to find with "Find Computer" are 
not found.


What I've noticed
=================
1 - I can't find any NT machines.
2 - I can access the 1 Win2000 computer.
3 - I have 6 machines pointed at the WINS server (1 NT, 1 95, 4 Linux). 
  NT still can't be seen by the Client.  95 & Linux machines can be seen 
through "Find Computer".
4 - I have 1 Linux machine in it's own workgroup (points to WINS).  I 
have the other 3 machines in their own Workgroup (also point to WINS). 
Both Workgroups are also inaccessible through "Entire Network".
5 - Since machines are DHCP, it's very difficult to net view from 
Windows to a IP address.  I can only net view the WINS Name.

If there is anything that I can answer, or if anyone can point out 
something that I am missing, please let me know.... no matter how 
insignificant it may seem.


Thanks
