Hi Scott,
You can get definitely get the computer name from the environment variables, but your form will have to be set to Full Trust security.
Qdabra Software pays for this free forum and our goal is to respond to 90% of all posts, but we can't write code for everyone who asks since it would take too much time and we are a small company trying to stay in business. If you're able to purchase a single support pack (Qdabra->Consulting->Support->...), we'd be happy to help you write and/or review the code to make it work. It's pretty simple though and you can probably find a sample if you search the forum.
Thanks!
