I have been trying to switch my concurrent licenses to node locked for several months now, it isn't a standard pricing plan they offer and is very difficult to get so I suggest you only consider that as a last resort
Wow, I didn't know that it was a different price for different type of license. The more I think about this, the more it sounds like a bug. I know in QARun there were commands that would allow you to change the system dates and times. Since QARun uses the same license manager it would seem that this should be fixed. That being said I believe that the current license manager is being replaced with a Compuware built version. Let me check with some of my connections and see if this will resolve the problem.
Compuware does not sell a node locked license, all of them are concurrent. The way you can "lock a license" to a particular machine is to have a separate license config install that only houses one of the concurrent licenses, accessible by only one machine.
There is not price difference, its just a configuration.
