RDS users are getting denied connections
Posted on 2013-01-24
I have a set of users that either remote in (via RDP) from outside locations or user thin clients inside of the office. They have a Windows Server 2008 R2 server acting as the DC and RDS server (I know I know, don't get me started on that). There are only a total of 15 users inside and out for this location, and only 12 remote in. When more users try to login, they get the following error:
"another user is connected to the server forcing a disconnect of current users."
There are 12 Windows Server 2012 USER licenses installed. RDS is running in a per user mode, and the licensing role does not report any thing wrong in diagnostics. The license server is published in AD. The license server NSA is a member of the TSLS group in AD.
The one red flag (or yellow exclamation in windows) is that it is not registered as a service connection point in AD. Hitting Register as SCP results in "the Remote Desktop license server could not be registered as a service connection point (SCP) in Active Directory Domain Services (AD DS). Ensure that there is network connectivity between the license server and AD DS." I followed a guide on technet about doing it manually, but everything was already done, so I'm not sure what this error is about and if it's the cause of the problem.
User report shows 10 of the 12 user licenses are used, so the 2 other users we're looking to connect should work fine.
Any ideas where to start with this?
