I have a windows 2003 and server 2008 vm,s installed on a DL3080 G5 running Vsphere. I notice that a continous ping will drop every now and then for about 10+ straight pings then it will return. I never lose connection with the host rather just the VM. Any idea's on what might be wrong? VMWARE shows no error events etc.

Are both VM's connected to the same Virtual Switch? or are they on different vSwitches with different physical NICS?

Are they on the same VLAN / Subnet or different ones?

The VM,s are one one virtual switch with one NIC and the management network is on the other NIC. They are both in the same subnet. I actually also lose the ping from the vm to the host, the ping from an external server to the host never drops but stops at same time that ping from VM to host fails.

I suggest that you check the speed and duplex setting of the pNIC at both the Host and Switch end.

If its set to Auto Negotiate, then set the speed and duplex to 1000/ Full or 100/Full based on your requirements.

Duplex setting were correct and no security on vswitch. I think my solution will be to install ESX 3.5 instead.

Could not play with system any more.
Complete reinstall of ESX on both servers fixed the error.
