Got some rare issue here, running CRM deployment manager in server, as screen capture below:
MMC could not create the snap-in.
CLSID: FX:{1ac9de3e-24ae-480d-9e15-65386b76e433}

First thing comes into my mind is to check for the following things:

• Run as administrator
• Run with user that used to install crm
• Run with domain admin account
• ping domain controller, IP address

unfortunately, still cannot resolve the issue, event log is throwing me:
Unable to obtain DNS hostname of Active Directory domain controller with ntdsa object name "CN=NTDS Settings,CN=WIN-6H9L2IUM336,CN=Servers,CN=Tier3DC,CN=Sites,CN=Configuration,DC=mydomain,DC=com".

If you guys faced similar issues, try following solution;

1. open regedit, navigate to :HKLM\Software\Microsoft\MSCRM
2. Right Click and click on NewString value as "PreferredDc"
3. Add the value to PreferredDc is YourDomainControllerName
4. We can find this in AD by typing the command in command prompt echo %logonserver%
