SCCM Failed to install Distribution Point (0x800706BA).
Check the distmgr.log file. If you see the line DPConnection::ConnectWMI() – Failed to connect to servername this means that SCCM server is unable to connect to the WMI namespace on the target machine which is why the installation of distribution point is failing. You would also see an error which reads Failed to install DP files on the remote DP Error code=1722.
You need to parse a MOF file on the target server on which you are installing the Distribution Point role. You need to look for smsdpprov.mof file which is found in <drive:>\Program Files\Microsoft\Configuration Manager\bin\X64 in your primary site server. Copy it to any drive or in a folder on the target DP server.
Run the command prompt (CMD) as administrator and execute the following command.
This will create the WMI name space and after this step you should be able to install the DP without any issues.
