Connection lost whenever I lock the computer

Question

I recently formatted my PC and installed Windows XP SP3.

Now whenever I lock my computer (Windows + L) or (Ctrl + Alt + Del) it loses the LAN connection.

Are there any registry hacks or something else that might be causing this? It didn't behave this way prior to the formatting.

Answer 1

From a quick search,

The sp3 install might have reset your power management settings so it goes into standby at 15 minutes (this is default on a lot of HPs). A quick google search shows that some people are having problems with sp3 and power management. If it goes into standby it will drop the network connection to save power. Set it to never go into standby or hibernate.

Try changing the power management settings.

Answer 2

In services.msc check for service ###string. if it is there disable it.
