I have a computer running Windows 2000 with 2 NIC. This server is not the PDC on the Network The PDC is a NT4.0 W/SP6 installed. One NIC has DHCP enabled to aquire an IP address from the cable modem ISP provider. The other NIC has a static IP address on a local lan. The server will work file on the Internet as well as set up a VPN Connection. The clients will ping 209.73.180.2. I can tracert 209.7.180.2 on the clients as well. They will not ping The clients IE version 5.1 will connect to but will but connect to I must use DHCP on the external connection as I cannot get a static IP address from the ISP. Is there a way to identify the ISP DNS?? Why do the clients not connect or ping Can the clients set up a VPN connection through this server or route through the servers VPN connection when it is up??

DNS on Windows 2000 Server

There's a bunch of questions here, maybe some clarification is required...
Do you have DNS set up for the lan, and is it set up for forwarding. See the other recent post on DNS in this forum.
Because the ISP DNS is not being accessed, the IP addresses are not being resolved, so you can access raw IP address, but not the names.
I'm not quite sure what you mean about the VPN access, are you suggesting using it for lan client access to or from the internet? Although there is no guarantee, if you don't switch off the server and cable modem, the IP address shouldn't change so external access through VPN is a possibility.

I saw in the other DNS post that you must enable fowarding and put in the ISP DNS server address. I do not have it. I have tryed to get it from RoadRunner and they would not give it out. In DNS do Zones have to be configured or just fowarding and the ISP DNS address? The VPN question is probably a routing problem and or question. The my Windows 2000 server will make a VPN connection to a VPN server as a client can my clients on the local lan pass through the local lan server VPN connection.
First off, you don't need RoadRunner's DNS servers, anyones will do. If you have a hosted website, you should be able to get the IP's of their DNS servers.
Secondly, FAQ's on DNS from Microsoft as a start. If you don't get what you want, come back and ask.
Thirdly, I have no idea about forwarding via VPN, I had enough trouble getting external access working, let alone passing through! Maybe someone else has an idea?

First, install DNS service on the server with those 2 NICs,
If you are already using DNS on your local domain, you should configure this server as secundary DNS server.
If it is the only DNS server, then skip this remark, and set up a local DNS domain (non-registered !)
e.g. mydomain.com
In the domain MMC snap-in, select your server name under the DNS section,
Go to the properties of that servername, and then go to the forwarders tab, enable it, and fill in the IP address of ANY internet DNS server.
If you want to know the DNS servers of your provider, simply do a ipconfig /all, and look what IP addresses your external NIC has got from your ISP's DHCP server.
On your clients, make sure that they are using your local DNS server to resolve names.
(Go to properties of TCP/IP and fill in the local IP address of your new DNS server, set it as primary DNS server)
Also, on your clients, right click on 'my computer', go to network identification, click on 'properties' and then on 'more' and fill in the DNS domain name as DNS suffix (e.g. mydomain.com)
To allow your clients to use your server as internet gateway, you must set up NAT on your server.
Install RRAS, and configure it as NAT server :
Right click on your server name in Routing & Remote Access, choose Configure and enable routing & remote access
Click next
Select 'internet connection server', select 'set up a router with NAT'
Use the selected internet connection : select the external NIC.
Click finish
On your clients, set the server's internal NIC IP address as default gateway.
Now you should be able to pîng internet IP addresses from your clients.
If that works, try to ping to If that works, you will be able to surf the internet from your clients...
Good luck
