For some reason the additional CALs have disappeared. I saw them the other day in the Licensing area of the Server Management Console but now they have just gone. The office has been changing hands a lot recently and no-one seems to know who has all the licenses. I have found out from the people who sold us the server that the CALs were in an OEM format on "media kit" but no-one knows where to look for it. I would like to restore the CALs from the backup. I presume that the important files will be in the WINDOWS folder. Does anyone know which files need to be restored in order to sort out this problem?
