Some of the most common problems that we ran into while converting from a hub to a switched environment (in no particular order) were NIC drivers out of date, auto negotiate failures (hard coding the speed/duplex if the switch and nic usually fixed that, alignment errors on the switch were usually a good indication of that). Portfast not being set on the switch. Users having their PC's moved to different floors without them checking the port settings on the switch. Finding CAT3 wiring sporadically throughout the building, Servers not having the NICs hard coded. There were plenty more... But the problem usually got fixed by something in that document link that I sent.
