- Add a second server (ServerB) to the WSS Farm created above
- Configure the load balancing using Windows LB for instance (or using a hardware device)
- Note the Virtual IP address configured in step 3
- Creat a new Web Application and under Load Balanced URL enter the adress from Step 4.

If you change your mind about the load balanced URL, you can modify it afterward in the WSS Central Admin site: OperationsàAlternate Access Mapping link
