Ivan,  The system automatically creates the pnadmin account, and ensures that it is in the local Administrators group.  Our "database manager" service periodically checks on this account.  If you were to move it to Power Users, the service would automatically add it back as a member of Administrators.
Hi All,  vWorkspace creates "pnadmin" local admin accounts on Terminal Servers. Do those accounts have to be in Local admins group or I can change its membership to say, "Power Users"?  Thanks
PnAdmin account - Local Admin
