How to split desktop (PC/Server) when moving desktops in Windows Server 2012 GPO?

Question

Active Directory

I decided to make roaming desktops using GPO. I tested it on a test user and ran into a problem that roaming desktops work not only on PCs, but also on servers. On idea and it is conceived by melkosoft. But how do you share? So that working computers have one work table, and the server has another one and the same user, without creating an additional user.
That is, it is necessary somehow not to apply the policy for a specific server, how to exclude the server from the policy?

Answer 1

But isn't it possible to apply the policy to a group of devices?
