In the most customer environments, there is a KMS installed. If you are running the script for the first time on the Base-Image the following
message box appears:
If you have a running KMS Server and would like to rearm your operating system, please check the license settings of your vDisk on the PVS-Server, see http://support.citrix.com/article/CTX128276 for further information.
IF you select “NO” the script will execute “slmgr.vbs /ream” once.
