With thanks to the experts here, my network upgrade went smoothly and our SBS 2011 domain is up and running. Now, I'm working on setting up the Premium Add-on server. I want to achieve three things, and need advice. I have already installed the 2008 R2 server and joined it to the domain.
1. secondary DC: Basically, I want users to be able to log on, print, and access the internet if the SBS server is offline (reboot, service, etc) I take it this is possible, but I'm unsure what I need to do to get it working properly (promote DC? Trust for delegation? what about DHCP?) What roles do I need to install and configure?
2. Run network share to target Windows 7 image backups (I think I got this covered...not running DFS, but a simple UNC path should do. But if you think otherwise, please advise.)
3. Run SEP 12 manager. (I think I got this covered too...just unsure if I need to wait to set this up to get the DC roles working)
4. Is there any SQL that I can offload from the SBS server as well? What about WSUS? Can that aspect be moved to the 2008 R2 server without breaking the SBS console?
