Is this possible

... one isn't doing what the original poster _said_ he was doing.  As 
I've said twice now, this is a red herring.  Indeed, doubly so.  It's 
a red herring because it is irrelevant when one is using Active 
Directory database replication, and it is a red herring because it
is irrelevant to the situation that the original poster described.

Nothing untoward will happen if one uses Active Directory database 
replication, as I said.
