Got a weird situation with a compaq desktop. I upgraded the system memory to 1.2gb for a woman. She took the unit home, everything works fine, except she can't connect to internet. I got the unit back, and it connected to the network fine. The desktop still can't connect to the internet even after I did a complete system restore. Comcast agreed to replace her modem with a new one, and her friend's laptop can connect to the internet fine. She told me that the network connection showed connected, just when using IE, she got no server error. I tried the desktop with my network connection and I can surf the net with IE. Right now I told her to bring the desktop to her friend's house and try it there. If that still doesn't work, I'm out of idea. Any suggestions?
