As part of our Open Value Agreement we get access to most product’s media that we are licensed to whether via download or physical media mailed to us.
We have been so busy that we have not been into our licensing portal for a while:
Under Software Assurance benefits we have the ability to request the physical media which we do for archival purposes.
With the advent of OS loading via USB flash drive though, it is becoming less and less a necessity to order the media . . . other than having it in the software archive for the day we may need it and the ISO would be no longer available for download or on any of our storage systems.
SBS 2003 RTM comes to mind as a product that we no longer have access to via TechNet download or elsewhere, but we run into the need to load up every once in a while for client migration testing or recovery testing.
