Our domain consists of multiple Windows 2003 servers and two Windows 2000 servers as the domain controllers. The plan is to move from the two Windows 2000 servers to two Windows 2012 servers as domain controllers. Because there is no direct path to upgrade from Win Server 2000 to Win Server 2012, we need to upgrade the current two domain controllers to Windows 2003 (or Windows 2008) then upgrade to Windows Server 2012.
The short version of the problem….
Of the two current Windows 2000 server domain controllers (DC1 and DC2), DC1 has problems. We get the message, ”There are no endpoints available from the endpoint mapper.” This and other problems affects its ability to replicate and communicate with the DC2. And we cannot transfer FSMO roles between the two DCs because of these problems.
The basic solution to the problem…
From what’s been relayed to me, it appears my best course is: a) to shutdown DC1 and 2) use DC2 to seize the FSMO roles. And move forward from that point. What’s a little unclear to me is once I seize the remaining FSMO roles and move those roles to DC2:
“Should I simply run adprep on that single domain controller DC2?” (and move forward to Windows 2012 from there.)
“Or should I promote a new Windows 2000 server to domain controller and once again have two Windows 2000 servers for domain controllers?” (and move forward to Windows 2012 from there.)
And once adprep has run successfully, shouldn’t I simply be able to promote a new Windows Server 2003 (or Windows Server 2008) to domain controller and move some or all the FSMO roles to the Win 2K3 (or Win 2K8) server?
But the underlying point here is that I am past trying to fix DC1. I need to find the best way to: 1) gracefully remove DC1…2) run adprep on the remaining domain controller (whether its DC2 or another domain controller)….and 3) move forward to upgrading to Windows Server 2012 as the final steps. I need to make sure to do whatever is needed before I shutdown and remove DC1.
