VPN and Windows 2000

I am using Windows 2000 Server as a VPN server through its routing and remote accesss. I can connect to the VPN and access the Internet through the VPN but can not map to the server. In fact I can not even ping the server. However, I am still able to access the server (that is not on the VPN network) on my side. I dont know how this works since I am connected to another network through VPN. I know I am using the VPN network because when I do a tracert it orginates from the VPN network.

Its confusing...could you please explain it clearly?

Are you using DHCP or Static IP Address ?

Nirmal Sharma

If you are using DHCP on the same server then Internal Interface must be configured for DHCP server to transfer IP Options to client machines. If you are using Static IP Addresses (a pool created on RRAS Server) then you should configure a Static Route back to VPN Server.

Also make sure NetBIOS over TCP/IP is enabled on Server. Enable IP Routing on IP Tab if you want clients to access network resources.

Let me know.

Thanks

I found the problem, the 2 networks had to be on different subnets in order to route correctly. I do not have NetBIOS installed, why did you think it needed to be?

Nirmal Sharma

No when browsing shared resources....Browser Service collects informations about resources using NetBIOS Names and not domain names. That's the reason i said that :-)

Anyway you solved it.

I followed the steps in http://techrepublic.com.com/5100-6268-1032135.html to setup a VPN. VPN works fine but I keep getting an error in my system log, event ID: 4199.

The system detected an address conflict for IP address 23.233.136.10 with the system having network hardware address 00:12:15:39:20:D9. Network operations on this system may be disrupted as a result.

I followed this instruction:

"During installation, you should choose to statically assign IP addresses. You’ll need to set up one network card with a true Internet IP address and the default gateway of your Internet router. The other network card should have an IP address assigned to the local network, and it should not contain a default gateway. http://techrepublic.com.com/5100-6268-1032135.html"

Even though I did this, why would I be getting an error? the vpn works fine..

Did you stop and restart RRAS service?

You get this error...which client is assigned this IP Address ?

23.233.136.10 is my WAN IP, no one is assigned to it but that NIC.

Nirmal Sharma

Sorry for late response.

Did you solve the problem or we shall continue now?

I just took the nic out of the server, it seems you can run a vpn server with only 1 nic. Is there a reason the article says you need 2?

Nirmal Sharma

>>>Is there a reason the article says you need 2?

Which article says? Two NICs conflict only if your system is Master Browser and you have difficult browsing the network.
