I am having a problem with my server not releasing Licenses  I have 20 licenses and when the students exit the program it will hold about 6 licenses for the entire time out period of 2 hours.  We have upgraded the license  software, designated ports in and out.  removed the fire wall and virus software.  Switched the server to a different computer.  Tried setting the time out period to 60 seconds.  None of this seems to work.  does anyone have this problem? Pleas help
