HTTP Error 401.3 when browsing CRM page

If this error happen to show when browsing CRM page:

HTTP Error 401.3 - Unauthorized
You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server.

First navigate to CRM application pool, check the Anonymous setting. Find out what is the identity.
By default is set to IUSR.

Then navigate to CRM folder, make sure you gave the permission to "IUSR" & "IIS_IUSRS" read and write permission. Remember to replace child permission for all items in subfolders.

This steps solved my issues ;)

CRM Deployment Manager: MMC has detected an error in a snap-in

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%
