My XenServer lab has been updated / upgraded, XenDesktop is now 5.6, XenServer 6.0.2 and Provisioning Services is 6.1 now. I had one issue with this last one, I wasn't able to create a new golden image for my brand new XenDesktop 5.6 setup... I was able to create the new VHD through the PVS Wizard but once the VM rebooted the connection to the VHD wasn't initialized... I knew it was a network issue but I had to remember a very old issue I had with PVS 4 or early 5... First you need to uninstall XenTools and the PVS Target Device agent. Reboot and install XenTools. After you have installed the XenTools and rebooted your Windows VM you need to do the following: Type in a command prompt Then type Start DEVMGMT.MSC,  click in the View menu, and then chose Show Hidden Devices. Expand the Network Adapters tree and right-click the dimmed network adapter, to uninstall it
