Thanks Jacko.
Normally use Spiceworks for the licensing, but it's a bit of a biatch. Thanks for openaudit, didn't know about it, will investigate further and see what it is like.
I've rebuilt 90% of our machines, and I am using a single VLK key for all the OEM machines, that makes life easier. Don't have 5 of each, most machines are XP, small number are Vista.
That spreadsheet they sent me looks inmense, will sort it out.
Just makes me think, if we didnt have VLK, and just purchased OEM and Retail, MS would never know about anything really.
Not bothered about the audit, as it's good practice and will learn from it.
