enable routing and remote access in server 2003 prevents loss of network access to users?

i tried to enable routing and remote access, so that i can set up VPN. soon as i enabled the service, all the people on the network lost access to the network drives, and exchange connection.

any reason why this happens?

Was this server a DNS server the client were using prior to you setting up RAS? If so, that's your problem.

Do you have your server connected directly to the Internet modem or do you have a router? If you have a router that connects you to the Internet and you try to enable routing on the server then you will have a major problem. You just need to configure it with the right settings and you will be fine. Give me a better idea of what you are working with and I can help you more.

yeh all i want is vpn connection setup. i have tried it on virtual pc's as testing, and read the book, and pretty much followed the steps as i have never set a vpn connection before.

when i right click the server, then click configure and enable routing and remote access, it enables the service, but then the network is not available to all the users. then exchange stopped working.

i would appreciate any pics / tips please :)

Since you are using RRAS I am assuming that you have 2 NICs in the server.

Make sure you only have a default gateway configured on the outward facing NIC.  This is what got me when I played with RRAS many years ago.

Because this server is also acting as a DNS server, you need to review and follow this article to prevent the server from registering its VPN IP address(es) in DNS and therefore causing the problems you're experiencing:

Hello,
Is this a standard 2003 server or SBS?

Also it sounds like you are using the RRAS setup wizard. There are 2 options related to vpn, one is remote access and the other is vpn and nat. Be sure to select the remote access option. Also on the next screen where you select the interface besure to uncheck the box at the bottom to enable firewall settings as this will block most access to the server.

Hope this helps

After you tell it to enable and configure RRAS and the wizard comes up, make sure you choose "Custom configuration," then select only the VPN checkbox.  If you select "VPN and NAT" from the first list, you can end up with nobody being able to connect to the server.

Ah.  Since it's SBS, use the remote access wizard from the Internet and E-mail section of the Server Management console.

Try the wizard first, and if that alone isn't sufficient to fix the issue, go with hypercat's suggestion.  (Hypercat will never lead you astray; it just wasn't apparent that you were on an SBS server at the time, and SBS can turn on you if you don't use its built-in wizards.)

can you please post the results of IPCONFIG /ALL and ROUTE PRINT before and after your VPN is established? or, in other words, before and after your local users are disconnected from the network?

i believe this would help us troubleshoot the problem.

thanks,
bbao

@Rakz0r - As DrDave242 said, since you're on SBS, running the wizard should be sufficient. It should do automatically what the article describes doing manually.  If not, you can still try the steps in the article also.
Cheers,
Deb
