Sort of a strange problem.
One of the computers at the office here loses connection to the server. It won't connect to the shared drive, the internet, email, etc. When it loses connection if you try to ping the server it comes back with 'timed out'.
Here is the strange part. If you restart the computer (or if you disable and reenable network connection) it is back up and running. For about 15 minutes...then it loses its connection. We scanned for viruses/etc and checked all network settings. Still have the same problem.
The switch is a Linksys 10/100. No other computer are having this problem. What are some trouble shooting steps you'd recommend.
