We have one VM that had some networking issues this past weekend. We fixed the problem by vmotioning the server from host1 to host4. Host1 shows no issues or NIC problems. However, the one exception about this VM is that it is assigned a static MAC address inside Windows. That was done originally to solve an application licensing issue when we originally P2V'd it. My question, is that every now(and other VM's that are on the same host as this VM) and then we have issues with this VM and losing network packets, etc. Could having a static MAC address inside Windows(it was the MAC originally from the physical) cause some sort of routing issues? The VM Nic itself has a VmWare assigned MAC address, but the OS has a different MAC. If so, how can we fix?
