Error: When opening AX client

“The Microsoft Dynamics AX client cannot be started because more users are connected to the system than are allowed by the license.” 

Error: While opening the AX client system showing below error message.
“The Microsoft Dynamics AX client cannot be started because more users are connected to the system than are allowed by the license.”
However there is clearly mention in error that its an license issue, 
But the actual issue is we are not able to open the AX and without opening we can not change the license. Upppsss:).



This error should not come While there is only one user login the server and RDP.

SO to resolve this issue Try this:

1. Open SQL management studio
Run below query on AX data base

select * from sysclientsessions where STATUS = 1
there must be some records in this table

2. Stop AOS services
3. Now delete are records from this table
4. Now restart the AOS service and open the AX client.
5. You may need to change the license as well (If expired).
