Over the summer, I'm going to rebuild both of our DCs. Briefly, I'm going to
1 - Transfer the FSMO roles from existing main DC to other
2 - Transfer the GC
3 - I think the DNS should be OK, as other DC should have a copy
4 - DHCP - any suggestions on this?
5 - DC Promo down
6 - Rebuild
7 - reverse process above
8 - Reinstall misc software
Then rebuild the other DC
Have I forgotten anything?
