Failing Domain controller, what to do
Posted on 2012-03-29
At my site I have the following setup:
2 Domain controllers
-DC1 has all 5 FSMO roles, is a DNS server, and a global catalog
-DC2 is DNS server and Global Catalog
I noticed yesterday that DC1, which has a software RAID 1 config, lost one of its disks. I'm trying to be proactive and figure out what I need to do.
What I was thinking is that I do the following:
1. Transfer all FSMO roles over to DC2. Once that has occurred I will then reboot it.
2. On my client computers and servers, I will then change the primary DNS to DC2, and secondary to DC1 and then reboot them
3. I'd also make sure to do this in the DHCP scope.
Will my solution work, or am I on the wrong path?
The reason I'm not looking to replace the disk is because it is a very old Dell 2650 and I have replacment DC's coming from Dell; however they are going to be 2008R2, which I already have a migration path for.
