I have a customer who purchased a new dell server with SBS on it. Additionally they bought a 25 user CAL to bring the total number of users to 30. For whatever reason the 25 user license number has disappeard off the server when I looked at the license screen. We have so far been unable to locate the paper certificate. does Microsoft keep a log of the license number that I can retrieve to put it back in there? If so where do I go to get it?
