Hello Lounge, I was recently trying to sort out a connectivity problem in a small office.
There are three Windows XP Professional machines in a (wired) workgroup, connected through a router to the WAN. Pretty much like you'd have at home. One morning, two users came into the office first and one (Nikki, the boss) was browsing the internet, and the other (Alex) was doing some stuff locally on her own machine.
An hour later, the third user (Debbie) came in, started her machine, and couldn't get on the internet, though Nikki was still on it. Debbie phoned me for help, and I got her on to a Command Prompt and found she had an APIPA address. I got her to do the release/renew thing but she still got an APIPA address. She couldn't reboot the router as Nikki couldn't be interrupted, and I didn't think it would help anyway, as Nikki was using it ok. Alex couldn't get on the internet either.
It was early in the morning and I couldn't get my head round it <g>, so I said I'd call her back. The fact that Nikki was on the internet threw me. A little while later, she called me back and said problem solved, they just restarted everything - all the machines, router, lights, central heating and all. Feminine thinking I know, but it worked.
So my question is this: can a frozen router keep you connected, provided you're connected before it freezes? A stalled router was the only thing I could think of, frankly, but maybe there was something I didn't think of.
