single user vpn access 1

[G0ldeneye]

Hello,

I'm trying to set up vpn access to my 2k3 server at work. When I add the VPN/RRAS services, I lose internet connectivity. I think I need to configure something in the DHCP relay agent because I got some message about it right before the installation of VPN/RRAS ended. My problem is I don't know that much about routing so I don't even know what to do in the DHCP relay agent folder...if that is even the cause of the problem.

Does anyone know what I should try next? Thanks.

Have you enabled NAT/Basic Firewall? It may be the NAT issue. Quoted form

I found out I can enable incoming connections and not even have to go through the whole vpn/rras process, and ran into this problem-> thread779-767719

also, when I connect to the vpn, i can't find any shares on any of the servers. How do I browse to these other servers shares once I'm connected to the vpn?

thx in advance.

Unable to browse through PPTP/VPN connection
Symptoms: 1. If the WINS server is on the same computer as the PPTP/VPN server, and you attempt to connect to a computer using a PPTP/VPN client, you may experience following problem: 1) The NetBIOS name of the computer to which you are attempting to connect is not resolved. 2) You may receive an error message similar to the following error message: "System error 53 has occurred. The network path was not found" when using net view or opening Network Knighthood.
2. If the WINS server is not on the same computer as the PPTP server and you attempt to connect to a computer using a PPTP client, you may be able to connect to computers on your local area network (LAN), but you may be unable to connect to network shares or resources on the PPTP server.
Resolutions: Inability to browse often means the client can't resolve NetBIOS names.
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.

Bada-bing! Thanks ChicagoTechNet, after learning tonight that they do not have any WINS servers on their domain I just typed in the UNC in the address bar and it works. I must've changed something though, because I think I tried that the first time and it didn't work.

Thank you for the feedback.
