Answer : differences between windows server 2003 and windows server 2003 r2

To be properly licensed, OEM requires the following:
 - OEM COA attached to the box (you indicated this).
 - OEM CD/DVD original media that came with the box.
 - OEM Manual that came with the box.

Without those three components that SBS box is not legit.

No, in the case of 2003 products, OEM means OEM media must be used.
