We were having some problems with this when I was doing some systems integration on our print servers. This was with Linksys LNE100TX, but I recall it happening on some 3COM cards as well. If we left it to Auto-detect the 10/100 and Full/Half duplex, it would occasionally flake out on us, but if we manually set them, it worked fine.

(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.
