Looks like 03/08 win server's NIC's stop working after migration. All ESXI host's are running the same version/EVC. Updating vmware tools did not resolve the issue. When adding a new network adapter to the VM the old network adapter as well as the new network adapter both start working. A reboot of the server does not fix the issue. As a band-aide I've just been adding a new NIC.
Has anybody else experienced this issue? Any ideas on what might be the cause/where best to look?
