Possible cause: Management point encountered an error when connecting to SQL Server.

Solution:  Ensure SQL server SPNs are correctly registered.  Review Q829868.

Possible cause: Internet Information Services (IIS) isn't configured to listen on the ports over which SMS is configured to communicate. 
Solution: Verify that the designated Web Site is configured to use the same ports which SMS is configured to use.

Possible cause: The designated Web Site is disabled in IIS. 
Solution: Verify that the designated Web Site is enabled, and functioning properly.

Possible cause: The SMS ISAPI Application Identity does not have the requisite logon privileges.
