I Have 70 vm's that have the vmxnet3 nic. Every time a clone or disaster recovery copy occurs windows 2008r2 redects the nic and the original is ghosted all ip info is lost. I have found the post sp1 windows patch but it wipes the nic during install. I thought I could use the vmupgradehelper tool to save the nic settings vs manually configuring the nic after the patch and ghost nics are removed. So far no luck vmupgradehelper doesn't error using the save switch or restore but doesn't seem to work. I'm trying to avoid doing them manually any one else deal with this on existing vms. right now I'm using netsh to backup what I can but it has a bug in 2008 and doesn't pull dns or I other settings. Only ip and mask are backed up.
