Windows XP Returns Negative Ping Times
After narrowing it down to the processor itself I started to put pressure on AMD for answers and was finally told to update the processor driver for all systems experiencing the problem. I did this at home last weekend and at work to almost a dozen servers and it has fixed the problem on ALL workstations and servers.
From my discussions with AMD I have pieced together the following likely issue with the dual core processors. It seems there is a timing issue between the two cores that slowly causes the timing to drift further and further apart between the two cores. This is why rebooting the machine temporarily fixes the syptoms; atleast for a couple of hours. The longer the system is up the worse the problem appears to get until simple tasks such as web browsing and copying files becomes untolerable.

For those that may feel this problem still resides on the network side I can only say in the past two months I have tried 5 different brand NICs (netgear, HP, linksys, d-link, and an older Compaq server NIC), 4 different switchs (Cisco 6513, Cisco 2950, Netgear, and D-Link), and tried a straight crossover cable between two computers and non had any affect on the problem. I have also experienced the problem on 3 different system boards (Compaq DL385, MSI K8N Neo4, and an Asus board. I have flashed the BIOS repeatedly on all these boards and the Neo4 ensured I was running the latest nForce4 drives. None of this troubleshooting has any affect on the problem.
In the past two or so months I have read about a lot of people having this problem but have not seen a fix for this posted anywhere so I am hoping this email can help at least one person save the months of meaningless troubleshooting I have to go through.
If you find this to be help full at solving your problem please take a minute to spread the word.
