guest network problem


My setup looks like this

Physical servers – DL 380 G6

OS – ESXi 4.1.0 build 260247

Storage – Clariion CX4

Switch - Procurve 2510G-24 (J9279A). s/w version - Y.11.16 ROM - N.10.02

Network – each ESXi server has 4 ports

Two of them are connected to corporate LAN

Rest two are connected to Procurve 2510G-24 (J9279A). IP address range of 192.168.X.X

Guest VM – windows 2008 64 R2

Each guest VM has two virtual NICS

One – E1000 connected to corporate LAN (10.X.X.X IP address)

Second – VMXNET3 connected to Procurve 2510G-24 (J9279A) IP address range of 192.168.X.X

The problem –

I see excessive broadcasts detected….on port which is the 192.168.X.X network.

We have networker backup server which has 192.168 IP address and it tries to backup data from the guest OS and the backup fails.

I have not created any teaming on EXSi hosts…..just plugged in two network cables from each server to the procurve switch. I am not sure if this is causing looping.

On the guest OS, I see the following

Event id 2012

While transmitting or receiving data, the server encountered a network error. Occassional errors are expected, but large amounts of these indicate a possible error in your network configuration. The error status code is contained within the returned data (formatted as Words) and may point you towards the problem.

Can someone please guide me on what could be the issue. Thanks
