One of our users is at a clients and is using our company's VPN to connect to us. She can connect to our network resources fine. She can send and receive email. However, as soon as she opens a browser to connect to the World Wide Web, she gets the following message: "There is an IP address conflict with another system in the network". I had her run ipconfig /all. There was no conflict between the local NIC's IP address and the address of the virtual adapter provided by the VPN (one was 10... and the other was 192.168...). Where do I go from here to resolve this issue.

So your network is a 10.x.x.x and the clients are on a 192.168.0.0?

Are they behind any other networks? Can she trace route out to say google? Where does it begin to drop?

Go to your Event Viewer | System log
Should be an error (probably 4199) with a source of Tcpip
It will tell you wihch IP address is conflicting

Configure a split-tunnel for web requests to go through their own internet connection instead of the VPN connection.

We checked the user's logs. The conflict was with the 10.x.x.x address provided by the people who's office she is visiting. We know where to take it from here. Thanks.
