Recently, a W2012R2 RDS I am managing has started balking at incoming RDP connections with the following message to the users:
The number of connections to this computer is limited and all connections are in use right now. Try connecting later or contact your system administrator.
Articles regarding this message are few, far between and rarely related to RDS, so I turn to you fine people in hope that someone has a good solution to this issue. In an attempt to circumvent the problem, additional RDP ports have been opened, and it seems to have helped some, but it is not a reliable solution.
Thank you for your response! The server is already fully licensed as an RDS/Terminal Server with 100 per-user licenses installed with several still to spare. It has been running for years without issue until just 3ish months ago. Currently, only 13 users are connected (one 'Disconnected'), so I feel the issue must be elsewhere. – Bjørn H.
