WinXP pc stops responding

WinXP Home edition (hey, I didn't buy it!)...

User shares a road runner connection in her office with approx. eight other users. When she walks away from her pc for any given time and comes back to it...she can't access a webpage...email will not download, etc. She has to reboot the pc for everything to work. I'm going to check the pc this evening (after my day job). I've checked it in the past but it's been a while. I'm fairly certain I checked all power settings before...but I will start there this evening. Does anyone have any other suggestions? Is there something on her internet/network connection that I need to check? Maybe something is timing out? Thanks in advance.

Device manager->network adaptor->Turn OFF power management

Thanks Steve! I'll try that this evening and post results back tomorrow.

Power management under device mangager was already unchecked.

Under Power Options in Control Panel:

Standby was set to 15 minutes and Enable Hibernate was checked. I set standby to Never and disabled hibernate.

Who is the isp?

Time Warner Cable

That's aol is it not?

It's Road Runner. Now whether that's the same as AOL...I'm not sure. I don't deal with Road Runner a lot.

Here's the local website for Road Runner:

A damaged connection file may be causing the problem. I know how to do it with aol which is as follows:

Go into the control panel and ensure you are in classic view. Go into add/remove and look for the isp connectivity service. If there click repair and restart the computer. Sign on to the isp again and the modem will be detected. Confirm the modem type and click next and next again. Choose the access numbers and click next and you will be returned to the sign on screen.

As I have said this is how to do the repair when using aol and I don't know if it is the same for other isp software. Maybe one of the experts on Vdr could help.

The only other I could think of would be to totally uninstall the isp software and the modem and reinstall.

Sorry if this doesn't take you anywhere.
