"Strange network problems" can be caused by DUPLICATE IP ADDRESSES. If the workstation can send traffic off its segment to another subnet in our 138.26 class B address range but can not get to a location off campus, it is very possible that the workstation IP address has been incorrectly set to use the campus gateway (184.108.40.206) instead of its own address. Problems within your building network that affect only one or two machines can be caused by duplicate addresses, also.
One way to check for duplicate IP addresses is to look in the arp cache of the machine having problems. In Win 95/98 or NT, at the DOS prompt type the command "arp -a". For entry of 220.127.116.11 you should see a MAC address starting like 00-00-a2....
