Citrix Terminal Server License Server problem
One of our customers is using a Citrix NetScaler appliance for SSL VPN capabilities for remote users. I tried to start an application (RDP Client) through this SSL VPN solution, but I couldn’t succeed. I was able to login and I would see all the published applications, but when executing one, I received the following error message:
The remote session was disconnected because there are no Terminal Server License Servers available to provide a license. Please contact the server administrator.
So I did contact customers system engineers, because I thought the problem was related to the customers Terminal Server License Server environment. I thought this, because I was still able to use SSL VPN solutions from other customers. They couldn’t find any solution for my problem and that’s correct.
The solution for the problem is found on my own laptop. I stumbled upon this TechNet article. I opened my registry and deleted the following folder and subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing\Store\LICENSE000
This did the trick. I was able to execute the published applications again without any problem after rebooting my laptop.
