I have a couple of Optiplex GX260's bought together in April 2003 with WinXP Pro installed. Both have recently started to drop their network connection a couple of times a day at random times. Both have Novell clients installed. Has anybody got any ideas for me to try please? I have unchecked the box in the network card properties that allows Windows to turn of the device to save power, but this has not fixed th problem.
