I see this on a 2008 R2 server. It has 2003 per-device CALS and 2008 per-device CALS. None of the 2003 calls are used; several of the 2008 cals have been used. But there are 900 temporary per device CALS issued, for only 10 machines that need licenses. (This is for line machinery.) When I look at what devices has the licenses, they are all listed as "unknown". These are scan-guns using Windows CE.
Suggestions? I am thinking this is an issue with the Windows CE/scan guns, but how to verify?
