A user cannot login. I check the pc and it has no ip. I swap out the lan connection from the connected computer next to it and it still won't connect. Hmmm, looks like a bad nic. I take it back to the server room and plug it in. It connects immediately and works perfectly.
I am going to take a laptop that I know works, back to the room and plug it in. Then see what I get for a connection. I did notice that when I tried to connect a switch in the room it would not work properly either. Out or 4 computers I had connected, only 2 would get a connection. It is at times like this that I wish I would have spent some money on a good network analyzer tool.
I think that there is a problem with the wiring in that room. Of course, this is the president of the schools son, who is next inline for the top job. Murphy's law of network connections.....lol
