Wondering if anyone had any advice for me.
I have 2 Server 2003 SP2 machines right now, one holds all 5 roles and the other is a backup. They are on the same LAN. Functional level is 2003.
I'm adding 2 more DC's and demoting these two. The new ones are 2012r2.
I installed the ADDS role on the first new proposed domain controller. The first time I ran DCPROMO from the server manager it took a bit to run and finally failed out complaining about a system connected to the machine was not functioning during the initial forestprep. After reading the logs its apparently an access denied error that it can't contact whichever server I have as the schema master. Since running adprep /forestprep since then, both from server manager and the disk, it fails immediately with the same error each time on trying to create the same object in the schema, I can look up the GUID if need be.
I'm not sure which permissions I'm missing, I am every type of administrator out there and local admin on the machines.
I also get this running a DCDIAG.
The File Replication Service SYSVOL ready test
The registry lookup failed to determine the state of the SYSVOL. The
error returned was 0x5 "Access is denied.". Check the FRS event log
to see if the SYSVOL has successfully been shared.
However, SYSVOL and NETLOGON are there, shared and healthy (replicating).
Another problem is when I look up the schema version it is 69, meaning 2012r2, so it looks like it already upgraded the version number, but not all of the schema. However, I can't add a 2012r2 DC without doing a forestprep first. And I wasn't sure if I should try to run a 2008r2 forestprep since it thinks it's already 2012r2. Would that hurt anything?
Any help would be really great.
