VMware Esxi 4 virtual machine cannot communicate outside of host

I have an IBM x3650 server running EXSI 4 and 4 virtual servers all running Windows 2008.  3 of the servers communicate perfectly with the Internet, host, other servers on the host and other devices on the LAN.  LAN is a single subnet /24.  One server can only communicate the host and servers on the host.  Tried changing static IP, adding second virtual network card, deleting all network cards and re-adding single card.  Tried both E1000 and  VMNET 3.  Then I added a new virtual machine with Windows 2008.  The new machine now could not communicate outside of the host but the original machine that couldn't now can!!  Stranger than fiction.  Does anyone have a clue or suggestion?  Thanks Milt

Thanks I will check the vswitch and Cisco physical switch.
Make sure the ethernet is connected in the vm config.
Make sure your vm are tied to a vswitch
Make sure your vswitch is tied to 1 or more external ports.

You can do all this from the vi client.

Also check your vlan config.
Might want to set the port on the cisco switch to:
switchport mode access (if not using vlans) or switchport mode trunk (if using vlan)
If using trunk port with multiple vlans, make sure you allow the vlans in question.
Make sure your port security does not have any mac filters.

But considering the changing symptoms, it might be a good idea to update the Broadcom firmware and the Broadcom drivers
