We have a pretty nice piece of hardware set up to run multiple virtual machines in vmware and one of the vm's is an instance of Windows Server 2003 running SQL Server 2005. For some reason we occasionally see 10-20 seconds of straight packet loss to this machine from remote machines (my workstation) as well as other vm's on the same physical hardware. I am using PingPlotter to keep a close eye on the packet loss.
So far we've turned off flow control on the NIC but we are already running out of other things to try. What might be causing this and how can I identify the problem?
Note: We also have another server with a very similar configuration with the same type of problem to a lesser extent (because its not used as heavily?)
