It just refuses saying:

Try Connecting Again. If the problem continues, contact the owner of the remote computer or your network administrator

So eventually we had to do the following after everything else we could think of failed:

Log into a domain controller

Find that user in AD

Open Properties and go to Remote Desktop Services Profile

Tick

Deny this user permissions to log on to Remote Desktop Session Host server

Click Apply

Untick

Click Apply

And it was resolved.

It still took a few minutes to get the user logged in afterwards as the profile loaded very slowly the first time.

This can also be a maximum connections reached issue - check licensing for RD CALs and RD Gateway CALs

Yes the licensing can also produce this problem - if you exceed the number of licenses by double then the RDS server will no longer permit connections from clients and you will receive the

Message.

There is a limit on Server 2012 of 250 users and I think if you have built your domain from a SBS 2011 server there is a limit of 25

I am not sure where this live in ADSIEdit though.

Is there a Group Policy that dictates how many concurrent users can log in?
