Hi All,

I am having an issue where VM guests all of sudden loose network connectivity, we have to edit the settings, change PortGroup to another, swtich back, then everything works again. We are running on Vsphere 4.1.

Anybody had similar issues with and know how to resolve this?

Thanks

I am assuming you are trunking VLANs to your vSwitch. I have seen your situation occur if you have a tagged VLAN the same as the native (untagged) VLAN in the trunk. If that is the case you have a couple of options.

1. Change the native VLAN to something not being trunked
2. Remove the VLAN from the trunk and move the portgroup to being untagged

Good Luck

have you reviewed the possible causes at http://kb.vmware.com/kb/1004109 ?  If you are using VLAN's, you may need to enable STP.
