You could probably get away with putting a big While loop around the server code, but there is always the greatest TCP server example I have ever seen. It lives over at OpenG, the Open Source LabVIEW community. You can download and use it for free. There's even decent documentation right there online.
EXAMPLE - TCP Server at OpenGBeware, the code is not easily understood by the novice LabVIEW programmer. All you need to know is that you should only modify the VI called "TCP Server Example.vi" and "TCP Server Example Connection Handler VI.vi".
