Licensing error

I am logging about twice a day in event viewer this error -
"The product windows server is out of licenses. Use
Licensing from the Administrative tools folder for more
information on which users are out of compliance and how
many licenses should be purchased."
When I look at our licenses we are per server and have
plenty left.
The error in event is a 202 error, but I cannot find
anything helpful when I look it up.
Any and all help would be appreciated.
