When I get the oem media for SBS, the cd packaging itself comes with 5 cals, the certificate is not shiny/holographic and there is not a sticker on it. If you have 2 pieces of paper with codes on them and the wavy hologram microsoft paper, you may have more cals than you realize.
example: i order a sbs server
in the media pack theres a piece of paper that says I get 5 cals, same shrink wrap as the cds. SBS knows about these 5 cals from the get-go.
If i need more cals, i order the 5 or 20 pack and that usually comes in a separate plastic wrapped package. These certificates have the ms logo and look fancy and have the code to type in to the license manager.
I have known the cal certificates to stick together and several times I have recieved more than I ordered, check your bill and packing labels.
