Windows 2003 HyperV VPS is Experiencing Negative Ping Times or Extremely Long Ping Times
When you are on your Windows 2003 Cloud Server, you receive negative ping times or extremely large ping times when pinging a server from the VPS.
This is caused by a bug in the HyperV hypervisor. Each physical processor maintains its own independent clock which is synchronized independently of each other. This issue occurs when the HyperV hypervisor is pulling time data from two different CPU clocks.
Startup and Recovery

Reboot the server.
