MS Exchange 2013 Unified Messaging issue, or really an AD issue?

▲

▼

Where to begin... I'd like to first admit that I am not an seasoned Exchange tech. Second here is the environment: (2) 2008 R2 DCs and (1) 2012 R2 MS Exchange 2013 server - other Exchange servers were removed [I've seen remnants of these old servers, but UM has been working fine until yesterday]

Our Exchange 2013 server stopped picking up calls on the voice access number assigned to it, for Unified Messaging. When trying to restart the, it fails to start with the following message Windows could not start the Microsoft Exchange Unified Messaging service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion.

The service will hang on "Starting", but never actually start.

I proceed to the Event Viewer and see ALL sorts of Exchange related messages, however all pertaining to AD. For example:

Error 1007: MSExchange Mailbox Replication

So at this point I run a DCDIAG on the PDC (let's call is DC1, where the only other DC will be called DC2):

To top this all off, DC2 was acting up so I restarted it. It no longer boots into Windows, instead I get this BSOD:

STOP: c00002cb Security Manager Accounts Manager initialization failed because of the following error: The system cannot find the file specified.

What a cluster, right?

Forgot to add an important query, netdom query fsmo:

"The specified domain either does not exist or could not be contacted. The command failed to complete successfully."

Inlcuding the list of domain roles via NTDSUtil:

You'll need to reconfigure the time service on DC1. You can use the commands below:

net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm.exe /config /manualpeerlist:”time.windows.com” /syncfromflags:manual /reliable:YES /update
w32tm.exe /config /update
net stop w32time
net start w32time

Then run the following command to view the configuration:

w32tm /query /configuration

C:\Users\Administrator>w32tm /query /configuration
[Configuration]

EventLogFlags: 2 (Local)

Make sure that the Type is listed as NTP and that NtpServer is listed as time.windows.com (or whatever time source you choose to use).
