I came in the next morning, reran all my tests and then that evening I promotoed a R2 machine. I again ran tests You will see some failures, these are normal since everything isn't completely replicating yet and looked for errors outside of replication, ISTG and KCC. Came back the next morning and reran tests again and everything was healthy and happy. Office Office Exchange Server.

I still use my SBS for email, which means it needs to be master of all, kinda reminds me of my control freak ex wife in that regard. So mine still runs DHCP.
It depends. Are you intending on taking the SBS completely offline? If not, leave it alone. Yes, exactly as you said, we have Exchange running on the SBS server and it unfortunately isn't going anywhere for awhile. Good to know about that, thank you. Need to research that more It has been this way forever and has nothing to do with SBS.
I know it has nothing to do with FSMO roles. I only mentioned it because Crimson kid did. And you can do superscopes on a standard windows network and have two active DHCP servers. I've just never managed to get it working with SBS, nor seen anyone else do it. I presume it's something to do whit licensing but I've never looked into it. Might test that one weekend and report back. I am just in the process of decommissioning all my additional DCs as since I added them I have had a whole heap of random workstation trust failures.
I know this doesn't make sense and I have spent the last year or so trying to work it out but the sites where I only have 1 DC, it never happens. As soon as I added a second DC to a smallish site, they started having the same issue. In the last year I have had a plethora of suggestions on how to fix the problem but none have every worked.
I removed the additional DCs from one particularly troublesome site and have not had an issue since. If your current DC is overloaded the you have no choice but if it is just for redundancy then I would suggest you look at a single DC with a replica on another machine.
Best practice is to have at least two DCs. A domain controller is the centerpiece of the Windows Active Directory service. It authenticates users, stores user account information and enforces security policy for a Windows domain. Customers are upgrading to the latest release of Windows Server and applying the latest innovation to modernize their IT environment.
The only impact of raising the domain and forest functional levels is that you will no longer be able to deploy domain controllers from older versions of Windows Server. To raise the functional level of a domain, you can run the mmc snap-in Active Directory Domains and Trusts. Right click on the domain name, and select Raise Domain Functional Level. In the window that opens, select the functional level Windows Server , and click the Raise button.
As an end-user reporting program, dcdiag is a command-line tool that encapsulates detailed knowledge of how to identify abnormal behavior in the system. Dcdiag displays command output at the command prompt. To open an elevated command prompt, click Start, right-click Command Prompt, and then click Run as administrator.
To register the console, click Start, Run and type regsvr32 schmmgmt. The built-in logs are the most important instrument for troubleshooting issues with domain controller promotion and demotion. All of these logs are enabled and configured for maximum verbosity by default. A domain controller must still be started in DSRM to restore system state data from a backup. You can use Repadmin. Those updates are then replicated to the other domain controllers in the domain. This is the reason why you see the same domain controllers listed as both source and destination DSAs.
Forces the Knowledge Consistency Checker KCC on each targeted domain controller to immediately recalculate the inbound replication topology. By default, each domain controller performs this recalculation every 15 minutes.
There are three domains of life, the Archaea, the Bacteria, and the Eucarya.
