I have a Windows 2003 Server running terminal Server. I only have 1 thin client currently running which has been running fine for the past 4 months. Now the 1 thin client is not checking in, Server says unable to start internal server / internal error. I am thinking this is a License issue, However I hate to pay $400 - $600 for a 5 user pack for this 1 thin client. Is there any way around this, or am I stuck paying Microsoft more money?
