I'm running into an error whenever I convert my Win7 template back to a VM. The VM will start just fine, but the Network Adapter on the VM will have "Connect at power on" checked, and "Connected" unchecked. If I try to enable the Network Adapter I get the error message "Invalid configuration for device '0'". I can fix this problem by simply removing the adapter, and adding a new one. This is fine until I convert it back to a template. If I deploy any VMs using this template, they will fail to join our AD domain using the customization template.
The frustrating part is everything was working just fine until after I performed a storage vMotion of some VMs. I'm unsure if it is related, but that's when I started seeing all the problems.
I've read quite a few posts on here and other places with people that are having the generic error message "Invalid configuration for device '0'", and this blog entry (Set-NetworkAdapter The operation for the entity VirtualMachine-vm- failed with the following message: &#8220;Invalid…) sounded like it would have fixed my issue, but the check always comes back clean.
