I work in a computer repair shop, and in the past week we've had 5 or 6 computers that can connect to the internet fine, but cannot see anything on else on the network. I've tried all the basic stuff reloading drivers, workgroup, release and renew ip, disable and enable card, and nothing seems to make any difference. I am sure its something completely obvious that I've just been overlooking but I can't think of what it is. The only thing that has fixed it is reloading Windows, which in some cases really isn't worth it. Some of the problems have been with Windows XP and some have been with Windows Media Center 2005. Thx in advance.
