VS 2005 Dropping Network Connections Randomly

All,

I am having the strangest last few days. Last Thursday evening one of my
Sysadmins ran windows updates on both the host and virtual servers in our
farm. One of the host boxes was hard rebooted and thats when the problems
seem to have started.

Our Setup
Host machines: Dell 2950 Dual Intel Dual Cores, 20 gigs of Ram, Server 2003
Enterprise. 2 Broadcom Nics. running Virtual Server 2005 R2 SP1
Virtual Machines: Server 2003 Standard R2 SP2 all held in there own SAN
Volume connected to corresponding Virtual Host. (ISCSI SAN)

The Problem: After the shutdown, 3 of the four Virtual Servers associated
with the host server would randomly drop connectivity to anything not hard
coded in the NIC card. For instance, both DNS servers and the gateway you
could ping forever. But, it would randomly drop to the File and Print
Cluster, and our SQL Cluster.

To ease everyones mind too. None of the other Virtual servers 8 in all,
spread out over 3 more Host servers (all hosts identical) behaved this way.

Now the strange part. If I shut down one of the offending virtual servers,
disconnected the SAN Volume it was assciated with, reconnected the SAN volume
to a host that was shut down properly and behaving correctly, brought the
server back up, Same behavior. While none of the other machines on that
server have this issue.

I have checked NIC drivers on both virtual and physical, on all hosts and
virtual servers. I have looked at my network. I have looked into teaming the
broadcom cards. I have looked at the clusters. Please HELP. I am at my wits
end. At this point I am just building new virtual servers in hopes of
correcting the issue.
