Disabling Bluetooth Dongles

I'm trying to find a way of stopping users installing bluetooth dongles. Not too much of an issue in our corporate environment but in our stores some PCs are on the sales floor and the users tend to be tech unsavvy....

Any ideas? Need a solution for WXP and W2K.

 

I use a little app that gives you a control panal app called "Startup ",
see: http://www.mlin.net/StartupCPL.shtml

In it, you can uncheck the Bluetooth Dongle drivers so that they are not loaded when system starts up. Its kind of like using msconfig, but a lot better in mho. I've used it on a number of computers to enhance troubleshooting. You can really have great control over what gets loaded.
