I will apologize in advance as this is a somewhat confusing situation with a bunch of back story. I will try to relay only relevant information.
We have 3 DCs in our parent domain, all 3 are physical servers and are (now) in the same physical location. We also have 1 VM in the cloud (Rackspace) which is the solo DC in our child domain.
For illustrative purposes, the DC's are as follows:
Physical DC's
- NRLHOURDC01
- NRLHOUDC03
- NRLHOUDC04
Virtual DC hosted in cloud
- NINAHOUDC02 (We previously had NINAHOUDC01 as our Virtual DC but ran into issues and ended up having to prop up another DC to demote that one....long story)
All 3 of the physical DC's have FSMO roles set to DC04.
NINAHOUDC02 FSMO roles are set as follows:
- Schema Master: NRLHOUDC03
- Domain Naming Master: NRLHOUDC03
- PDC: NINAHOUDC01
- RID Pool Manager: NINAHOUDC01
- Infrastructure Manager: NINAHOUDC01
When I try to set the FSMO roles for NINAHOUDC02 to NRLHOUDC04, I run into errors:
- Binding to NRLHOUDC04 ...
DsBindWithSpnExW error 0x80090350(The system cannot contact a domain controller to service the authentication request. Please try again later.)
ldap_search for attribute supportedCapabilities failed with 0x59(89 (Parameter Error).
AD Sites and Services is different on every single DC and I don't see all servers on any of the sites and services consoles. There are 4 sites: 1900STJAMES, 2506WMAIN, 4400, RACKSPACE. Our 2 old locations were 1900STJAMES (which housed NRLHOUDC03
and NRLHOUDC04) and 2506WMAIN (which housed NRLHOURDC01). I created 4400 when we moved to our new office, which we are currently in, and moved all of the DC's into that site thinking that as long as I added the correct subnet, everything would
fall into place. It didn't.
I've also run repadmin /replsum on each DC
NRLHOUDC04:

I've been troubleshooting this on and off for the past month or so and plan to do some heavy configuration changes this weekend but I don't know if I need to just start demoting DC's, clearing metadata and then re promoting or if there is an easier way to
force the DC's to see each other.
