[ActiveDir] FMSO roles split, patch question.

[John Strongosky]

We have our FMSO roles split between 2 dc's. They are Schema Master/Domain Tree Operator on 1 and on 2,  the roles PDC Emulator/Rid Pool/Intrastate on the other. After I apply the patches from Microsoft what is the beat practices for the boot order...or does it matter?   1. Remote DC/GC's first 2. no. 1 3. then no 2.     thanks
