forgive me if this should be listed under viruses... i just setup a pc for a lady i work with today, and when she came back from lunch the network card wasn't sending or receivign packets. so i assume the nic is dead. put a new one in same problem. then i notice i forgot to install norton my b. i checked for a few viruses, i ran stinger, and some fix tools from norton, such as netsky, mydoom and beagle, i also installed norton corporate edition but i am unable to update it due to me not being able to get out on the network. anyone have anyideas on why this machine would be acting up the way it is?
