We have 1 HP dl385 running Windows 2003 R2 64 Bit Server Service Pack1 (up to date with patches). We have 3 guest vm servers running Windows 2003 Standard SP1 and they are all up to date with patches as well. 2 of the 3 host are running fine. One of the three can not see the network i.e., cant send or receive any packets on either the virtual or physical networks. This VM has been running for 3 months with no problem. We had to roll back to a snapshot (owning to a Microsoft Exchange issue, nothing to do with the Virtual Machine itself) that was taken when the system was in a know good state. When we first got the snapshot up we were able to get the interface up by disabling and enabling it. We have verified that the network settings are identical to the other servers that are running properly. Now we cannot get the network interface up at all. Any help would be appreciated.
Thank you in advance.
