That reminds me, some more information on our problems with these cards: One of our machines would disappear from the network every day or two as well. It always happened at night (which I believe can be linked to more web surfing at that time, which leads to more traffic on that server). We were able to fix it by unplugging the cable and plugging it back in (which caused the interface to go up-down). We tried forcing it to 10MBit but that made no difference.

(And an earlier 905 variant) We had no end of trouble under Win 95 with some of these cards. In many machines (maybe 20%-30%) they would occasionally "lose contact" with the network. The only way regain a connection was to shutdown (not restart) the system, count to 15 or 20, and reboot. This worked 99% of the time. The other 1% required doing the process twice.

At DBU we switched to Linksys while I was there and only one failure and that was a DOA card. > > Jack > > On Tue, 07 November 2000, Yaron wrote: > > > > > Hi, > > > > Kinda off topic, but has anyone had this happen to them before? > > > > I've got a 3com 3c905-TC NIC.
