Not able to logon to Windows Server 2008 R2 Enterprise Domain Controller


I'm currently in the middle of a Disaster Recovery non-functional test. We have an isolated VLAN setup that will not affect production. We have failed over a large number of production servers and two domain controllers using site recovery manager. Each domain controller is part of an different Forest namespace. Before SRM each domain controller had it's DNS information updated in the Advanced TCP/IP Settings for the network adapter.

DNS server addresses, in order of use
IP Address (Current Production IP Address
IP Address (DR IP Address that will be used once the Domain controller  has been replicated using SRM)
IP Address (Of another production Domain controller
IP Address (Local Host IP Address

We can logon one domain controller but can't logon to the another. The logon is using hanging at Welcome then times out. I've attached a print screen. The following registry fix was also applied to production before replication.

As a domain controller running DNS I configure each server with as the first (and sometimes only) DNS address as this will work reliability regardless of what active IP address the adapter gets.

I think you're on the right track.  You may also have some services set to run with domain credentials.

I'm curious to know what the error looks like when it "times out".  

If the server has a valid IP address can you manage it across a LAN connection. Is there anything in the log files to provide direction?

In a DR scenario you should NOT be recovering domain controllers using VMware, unless you have DC cloning enabled (server 2012). In a DR scenario you should have LIVE DC's that are in the DR site. when you use SRM you only recover member/applicaiton servers. Doing it this way will mitigate any computer/policies/replicaiton issues which will stop you from logging in.
