ok, i'm having problems with my connection at school. I built a new computer, and it connected to our network fine for about a month. then the cannot be displayed page kept popping up. so i tried to repair the connection and it failed saying renew IP address failed. i told the network administrator of this a nd she told me that there was nothing wrong with their conection, it was my computer. so i replaced the network card that i knew worked. no difference. she also said that there could be spyware stopping my internet access, well i have adaware and it hasn't picked anything up and neither has my antivirus. So my question is, how do i fix this or is it the administrator that is blocking me and giving me a line of crap about it being my computer's fault. sorry for such long message. thanks for any help.
