I've got a weird problem. On Saturday night I converted a SBS 2011 VM from Hyper-V 2008 to VMware ESXi 5.0 using VMware converter. All went smoothly in terms of the conversion but have a wierd problem.
Every 6 hours or so the VM loses all network connectivity. It can ping itself but nothing else, even on the local subnet. A restart will fix it but even disconnecting/reconnecting the network or disabling and e-enabling doesn't do anything.
The Server has a new NIC as it is now running VMware Inel 1000mbps NIC rather than Hyper-v NIC.
Anyone seen any similar behaviour?
