I have a SUP internally and then a DMZ SUP that is configured to use the internal SUP as its sync source. I'm coming across PC's that are on the internal network where both the WUServer regkey and the WUAHandler log are pointing to the DMZ SUP (and failing) instead of the internal SUP. What could be causing that? In CM07, I had a GPO that configured the server but when I migrated to 2012, I was under the impression that a GPO wasn't required any longer. I thought about putting the GPO back in place but by forcing all clients to look to the internal SUP, the external clients wouldn't be able to access it for software updates. So I'm trying to figure out where the mix-up is happening that is causing some clients on internal subnets to look to the DMZ SUP for its SU's. Is it based on boundaries? Do I have a boundary configuration issue?
