The Terminal server client has been disconnected because its license could not be renewed

Hi,

I am getting "The Terminal server client TSSERVER has been disconnected because its license could not be renewed. The license server TSLICENSE was contacted to get windows server 2003 - Terminal Server Per Device Cal Token license for this client" error in Terminal server. But still some users are able to connect and some are not. We wil delete the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing  from the client machine and then it works fine. Attached the warning msg.

What might be the issue?

Hi,

We have opened support case with microsoft and told us this is due to mixed environment (both 2003 and 2008 license servers)

asked us to install the hotfix

Hi,

What value does the reg key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\Licensing Core\PolicyAcOn say?

If it is 2 ( Per Device licensing mode ) or 4 ( Per user licensing mode ) than it is ok, but if it says 0 ( invalid ) than you should contact MS and require a hotfix as described in this  Knowledge Base article 834651

the value of PolicyAcOn is set to 2. That article I gone through. as the value is correct, I think  no need to apply the patch

Is the licensing server the same as the TS? Perhaps the TS wants per user license where the license server is configured for per device ?

license server is different.

we have 3 license servers tl01, tl02 and tl03. and 20 Terminal servers equally pointing to all 3 license server. and these errors is randomly occurring in some server which are pointing to  tl01 or tl02 or tl03 license server
So I am confused, where to check. There won't be problem with all 3 license servers at same time. also if there is a problem in terminal server, it should not accept connection from any user, but all are accepting connections from users.

When a TS cannot find the right server/license it will revert back to its default license which explains why some can and some cant connect.

Could it be (but i am guessing here) there is a switch which is bugging, are you able to pin point the problems to certain pc's (so you can imagine if there is a particulair switch in the way?)

Hi,

means the issue might be from client side which are connecting to TS server?

Patrick BogersDatacenter platform engineer LindowsCommented:
Not likely, please compare type of license on the licensing server.

Are the client devices finding the TS License Server by means of a GPO?  If so, please verify the GPO config in order to ascertain that all of the license servers are designated correctly.  

The GPO is a better mechanism than discovery, so if the GPO isn't configured, it would likely be beneficial.
