MS workgroups over VPN tunnel

I have a main network 172.16.9.0/24 and a remote network 172.16.2.0/24. The remote network is operating in NEM via a 3002 hardware client with VPN 3015 concentrator as headend device. The hardware client acts as dhcp to just the .2 subnetwork. A 2600 router is between the .9 subnet and private interface of concentrator on the main site. I can map a network drive from a host in subnetwork 2 to a host in the subnetwork 9 no problem. In subnet 9 there is a DHCP server and DNS server(same machine). Using workgroups, hosts in this subnet can browse network neighborhood and see other's computers shares etc in just this subnet. How can I enable hosts in the .2 subnet to browse the .9 subnet via network neighborhood? I added the host in .2 subnet to the same workgroup as hosts in .9 subnet but that didn't work. -much thanks in advance.

Re: MS workgroups over VPN tunnel

This is more of a MS issue, but you should be able to get around it. The issue is that NetBios packets don't get sent over the VPN. There's some good information on it here:

This relates to VPN clients specifically, but the concepts are the same.

Some things to try on the remote PC's are make sure "Netbios over TCP/IP" is checked under the TCP/IP - WINS settings in their Local Area Connection profile, and also ensure that "Client for Microsoft Networks" and "File and Printer Sharing for MS Networks" are checked under this connection.

Re: MS workgroups over VPN tunnel

Thanks for the insight. "Netbios over TCP/IP" is checked under the TCP/IP WINS setting. "Client for MS Networks" and "F&P Sharing for MS Networks" are installed. I set up a WINS server and can see the host named "remote" (172.16.2.6) in the list of active registrations, actually i see 3 of the same computer name. I know that Netbios is passing through the VPN tunnel because I can type the name of a host on the internal network into the explorer bar on the remote host, ie: \\hostname. It then remains in the network neighborhood until i close explorer. However, I am still unable to double click on network neighborhood and see all the hosts on my internal network. Is it a problem if I have my hardware client configured as dhcp to the remote network, and the other information DNS and WINS is coming from the internal network via the IPSec tunnel? when I do an ipconfig /all everything looks correct.
