Resolutions: Inability to browse often means you have name resolution issue.
1. If this is a workgroup network, enable NetBIOS over TCP/IP on the server
and clients.
2. If this is domain network and the WINS server is on the same computer as
the PPTP/VPN server, move the WINS server to a different computer.
3. Add the NetBEUI protocol for your PPTP tunnel instead of, or in addition
to, TCP/IP.
4. By default, most routers and firewalls prevent the transmission of
NetBIOS names unless you enable UDP ports 137 and 138 and TCP port 139. Try
to enable UDP ports 137 and 138 and TCP port 139 across all routers and
firewalls between the PPTP/VPN client and PPTP/VPN server.
5. Make sure the client has correct DNS, WINS and Master Browser settings.
6. Make sure the default gateway points to the remote network rather than to
the ISP.
7. Some ISP might block ports required for NetBIOS name broadcasts.
8. If WINS address is not distributed upon connection to VPN, LMHOSTS should
be configured to enable Domain to be located.
9. If you try these techniques and the client still can't browse, try to use
UNC to connect to the remote resources by ip, for example, use the net use
h: \\serverip\sharename command.

Setting up VPN connection to work, using required software supplied by
work. It is Contivity VPN by Nortel and is not supported under WinXP by our
tech support so I'm on my own. I'm installing on WinXP Pro/SP1.
I can connect (it authenticates my UID and PW), but, I cannot browse to our
intranet or internet sites. I can ping the address of either site
successfully. Further, if I enter the IP address in the browser address
field, I can bring up the site. But, as soon as I click on a link to
another page, it cannot find the page.
Any advice on how to fix this?
