It is possible to have more than one certificate issued for a given DN,
but usually we try to avoid such things.   Some variation of this is probably
the right answer.  You'll have to talk to an enterprise CA provider to
understand if they do anything.  I suspect that if you can make contact
with the microsoft certificate authority people (I don't know them), they
will know if they have solved this problem.

I'm not sure if you read this part:
