I am not sure when it happened, but recently my network, including the server, dropped down to 100Mb and I cannot seem to get them back to 1gb. I think the problem is the server is not connecting at 1gb and therefore nothing else can. I tried multiple GB switches and multiple cables. The NIC on the server is set to Auto Detect its connection and when I change it to 1000Mb it drops the connection completely, although the NIC utility I use says it has the capability to connect at a higher rate. Does this sound like a NIC issue? I wanted another opinion before I took the entire network down.
