I have a very odd issue with one of my servers that is making me want to bang my head on a wall. I installed a brand new Intel Pro 100 PT and the most current drivers. What is happening is that every three days, almost like clockwork, the NIC starts dropping packets and connection and response times go to almost 1000 MSs. I reboot the server and it is fine for another three days or so. Now here is the odd part. I was having the exact same issue with one of the on board Broadcom BCM5708C NetXtreme II (Dell 2950 server) so I installed the new NIC. What is happening?! Many thanks for any help.
