SCCM 2012 r2 Management point not responding to HTTP requests

Question

_{Monday, January 16, 2017 4:48 PM}

Good day

We are experincing an issue where the management point has an error under site status. When checking the error message for the MP control manager process I get the following error message

MP Control Manager detected management point is not responding to HTTP requests.  The HTTP status code and text is 404, Not Found.

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

Solution: Verify that the SQL Server is properly configured to allow Management Point access. Verify that management point computer account or the Management Point Database Connection Account is a member of Management Point Role (msdbrole_MP) in the SQL Server database.

Possible cause:  The SQL Server Service Principal Names (SPNs) are not registered correctly in Active Directory

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 the site is configured to communicate.

Solution: Verify that the designated Web Site is configured to use the same ports which the site 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 MP ISAPI Application Identity does not have the requisite logon privileges.

Solution: Verify that the account that the MP ISAPI is configured to run under has not been denied batch logon rights through group policy.

For more information, refer to Microsoft Knowledge Base article 838891.

We would like to correct this issue as it might also be the reason why our SCEP clients are not getting new updates.

If your MP is not working, then nothing is working; without a functioning MP, clients cannot do much of anything.

Have you checked any log files? The MP logs are listed at https://technet.microsoft.com/en-us/library/hh427342.aspx#BKMK_MPLog

Often, simply removing an MP an re-adding it will correct any issues.

Also, have you validated that all pre-reqs are met? This is a common cause of MP failures.

Hello Jason

This is an old deployment it has been running for a few years. Only recently upgraded to r2. I have deleted the MP then reinstalled. It runs ok for a while then the same error crops up then ENdpoint protection starts reporting clients as at risk.

R2? Is there a reason you didn't go to R2 SP1 or better yet, Current Branch?

Also, what about the logs?

Hi,

    Did you install Mcaffee? 

    Have you tried to reinstall IIS like this thread? https://prajwaldesai.com/community/threads/management-point-encountered-an-error-when-connecting-to-sql-server.509/

Best Regards,

Ray
