I have learned many invaluable things in the past few days about P2Ving live production systems... but none so important as the following little gem. It seems that with most systems, when you P2V them you end up with Ghost network cards for each of your original physical NICs... that is, they do not show up in the device manager, yet they still use the static IP addresses you had assigned, do funny things to network communication and name resolution, etc. Here is how to get rid of them:
1) Open a command prompt and type in "SET DEVMGR_SHOW_NONPRESENT_DEVICES=1". You will not get a confirmation back, it will just drop back to the prompt. Now, in the SAME CMD window, without closing it...
2) Type in "DEVMGMT.MSC" to open the device manager from the command prompt. This is critical, if you dont open it from the same CMD window you typed the first step in, it wont work.
3) In device manager, go to View > Show hidden devices
4) Expand nic cards and right click on each fadded network card to remove it.
I tried following similar instructions over and over, and it was not until I launched the DEVMGMT.MSC from the command prompt that I set that first variable in that it worked.
Once I removed the ghost nic cards, set my static IP back to what it was supposed to be (as VMware converter gives the new vNIC a DHCP address) then rebooted, all was well.
