Hi,
I recently had a Windows 2012 server standalone on a workgroup. I took a server backup, stripped the server down installed the hyper-v role and restored the backup into a virtual machine to be used as terminal server and the base sever as the domain controller.
To change the SID of the restored server now as the guest I run sysprep but this failed at the last stage with a fatal error, but did change the SID and I was able then to join the terminal server to the domain and all appeared to be working ok.
But.. After creating a group of users that was added to the remote desktop users security group on the terminal server, on a reboot of the terminal server guest that group dissappears! and noone can login to the terminal server. So I go back to add the group
in again and it says the group is already added but its not in the list, so I rename the group on the domain controller to say rdpusers2 and I can then add it in again.. but then when I reboot again its gone again and I now cannot add the group rdpusers or
rdpusers2 it says its there, so i need to rename again to rdpusers3 and so on.
Any help appreciated its got me stumped.
Cheers
