Intermittent software?? m/b gigabit ethernet port hangs intermittently. Disable/(re)Enable network card in adaptor settings restores it 100%. Added a PCI network card which does the same thing!! I do not know where to look next.
well if you had motherboard nic card issues then added a nic card and you get the same problem, I would consider changing the cable from nic card to network card. then I would try to connect the pc to a different port on the router/switch to see if it continues, It may not be the computer at all
Hard to answer further as you did not answer Lutfij's question regarding your hardware.
where you get your windows Ultimate ? was it a cdrom or download ? I am asking because like Windows Enterprise very, very, few people actually bought windows ultimate.
