This is a wierd one...

Laptop is configured so that XP manages the wireless connection. However, every once and a while it drops it. It took me a little bit of digging to figure out, but the problem is that a configurtion setting keeps resetting itself! The key is supposed to be configured to shared, and was configured to shared, but it keeps setting itself back to open without anyone going into configuration -- when it does, of course, the connection is dropped. We have several other XP laptops configured the exact same way, and this never happens.

What could cause such a thing?
