I have done this before. What particular problems are you having? The main thing to be aware of is that you always have to have LabVIEW running for the web server to be active. If your machine restarts, you have to restart LabVIEW. You can obviously set Windows to do that automatically, but it's something to be aware of.
Also, make sure that no other applications are trying to use port 80. I've run into that problem before. You can download port scanners off the web that show you what ports are being used and by what applications. If you're having specific trouble, let us know and hopefully we can help you solve it.
