So, I have a 2008 R2 terminal server. It is also a domain controller. There are about 40 users connecting to it. 36 of them are lower level users and 4 of them are senior management. I have a user that will be assisting with supporting the 4 senior management users via terminal service manager or RD session manager as it is called in 2008. Here's the catch, when they open terminal services manager, that user can see ALL of the users connected to the server and can send them messages or shadow them etc... I do not want this user to SEE any of the users in the lower level OU, just the users in the senior management OU. There are various reasons for this that I won't get into and I know that I can set permissions on whether you need to require permissions to shadow another user, but what I need is a way to hide the lower level users from this support person and only allow him to see the sessions of the users in that specific OU. Any ideas???
