Nah... it's 32 bit Vista and SEPM is on a 32bit 2003 server.
I cleared the cache, updated the policy and sent an update content command from SEPM. I waited 8 minutes and then rebooted the client. Voila, the defs. updated.
So, do Vista clients just take longer to update? Was it something I did that allowed the defs to move over? I am clueless at this point.
