With Windows 2012 / 2012 R2, the administration programs in the Administrative Tools menu for RDP / Term Server / Remote Desktop Session Host server are MISSING unless you install the Remote Desktop Session Host (RDSH) role.
How can you DISABLE the default setting of, "RESTRICT USERS TO A SINGLE SESSION" in RDP? I find that when we have multiple administrators using the same account, it is EXTREMELY useful to NOT interrupt another admin when they are doing important work, and therefore it is necessary to DISABLE this default setting. Since in ADMIN mode you are allowed (3) connections (2 RDP and 1 via console), it can be very easy to accidentally interrupt another admin.
Furthermore, NOT being able to disable this makes the operating system LESS STABLE since you could potentially interrupt another admin at a critical time and accidentally cause havoc. Yes, best practice is to NOT share accounts, but this is not reality. It happens, whether they include this tool or not. And if you ADD the session host role to be able to accomodate this, you now are obliged to enable and install a LICENSE server or you are UNABLE to RDP to this server any longer unless you REMOVE the session host role and reboot.
How can we disable this default setting? Setting a GPO is possible but extremely invconvenient...setting local policy is also the same. I tried adding the SNAP IN for Remote Desktop Session host, but it is not avaiable. I have seen other posts referencing RE-ADDING the old Windows 2008 R2 DLL for the Term Server admin program and adding entire registry keys to accomodate this, but this seems dangerous and likely to cause an issue.....
Are there any other ideas?
