    Hello Nandan,

    May we know the current status if you tried these steps mentioned in the answers above?


    Please follow below steps to fix this issue.
    1. Ensure dp is pingable.
    2. Windows firewall should be disabled state.
    3. Copy this file smsdpprov.mof from primary server. such command
    mofcomp.exe smsdpprov.mof.
    5 wait few times.


    I think this error is only after upgrade, then you might need to restart the server and that might fix issue.

    If not, there could be some issue with Firewall ports and communication between SCCM server and MP

      Thanks Anoop for sharing the details. There were no changes in firewall port earlier this DP was working, but now it is giving a problem may be after the upgrade. So still we need to check the firewall ports?
