I have a Compaq Evo D310v Microtower with XP Pro, 256 Mb RAM, NIC is integrated with the motherboard.
For months now, it has been causing problems. When we got broadband, this was the only PC that wouldn't work when the DNS was pointed to the server instead of the router (and still is). After asking about, someone suggested changing the NIC, which I did. The first time I connected it up, to a point that I knew was working, there was no activity on the card. The card is ok as I have taken it from a working PC. I then tried it at another point, and it worked - picked up the IP address, still wouldn't accept the DNS from the server though, but one thing at a time. I tried another PC at the point where the problem PC couldn't access the inetwork, and it worked without any problems.
So, has anyone experienced anything like this before? Or can you at least point me in the direction of a solution. It's really annoying, so I'm assigning the maximum 500 points to it.
