Fix ConfigMgr DP Issue RPC server is Unavailable Error Code 0x800706ba | SCCM

Learn how to fix ConfigMgr DP Issue RPC server is Unavailable Error Code 0x800706ba. I have seen issues like SCCM package distribution is not working for a particular remote DP. When you see the issue is for all the packages, then this is something with network connectivity and Distribution point configuration.

The meaning of error code 0x800706ba is RPC server is unavailable. RPC is one of the core components of Windows. SCCM uses that component in many scenarios.

In the context of ConfigMgr, an RPC server unavailable error might occur when the site server tries to connect to remote DP’s Windows Management Instrumentation (WMI). There could be several reasons for the error code 0x800706ba. More details available in the following sections.

Event Logs

You need to check event logs (Applications/Systems) on the remote DP server to understand whether there is something wrong with the WMI repository or not. There could be health issues with WMI and that could also cause similar issues with SCCM package distribution.

Security Hardening

I have seen the scenarios like security hardening policies impact the connectivity to remote DP. This could also cause issues with package distribution. Event logs might give you some hints about the new security policies implemented on remote distribution points.

Firewall Issues

The other important point that you have to check for RPC-related issues is firewall ports. Well, this is not necessarily mean that the firewall application installed on your remote DP or primary server. Rather it’s more to do with firewall appliance from the network team. There might be many firewall devices in between two data centers where remote DP and primary server are located.

You need to make sure all the required Firewall ports are opened between remote DP and primary server. Do you know RPC Dynamic Ports? TCP 49152-65535.

Test the following port communication to confirm that there is no connectivity issues. Run the following commands from primary/secondary site server.

  • You can use port query(portqry.exe) to test the connectivity between the site server and remote distribution point.
    • portqry -n REMOTE_DP’s_IP -p TCP –o 445,135 -l TCP445portqry.log
    • portqry -n REMOTE_DP’s_IP -p UDP –e 135 -l UDP135portqry.log

Let’s check whether you are able to connect to remote DP’s WMI or not. You can try connecting to remote DP’s WMI using the WBEMTest tool available in Windows. There are a couple of considerations here. You can use either an admin user account or system account to connect to remote WMI or

I have seen in many blogs/forums that recompiling of MOF file (smsdpprov.mof) could help to fix the 0x800706ba error. But personally, I have not used this method to resolve the issues. I recommend raising a ticket with Microsoft support before you do this step.

  • Browse to Drive Letter:\Program Files\Microsoft Configuration Manager\bin\x64
  • Search for smsdpprov.mof file
  • Copy the above file to remote DP
  • Run the following command (as administrator) from remote DP
    • mofcomp.exe smsdpprov.mof

SCCM DP Logs

Check the SCCM log files related to DPs. The PkgXferMgr.log file is your best friend for remote DP distribution/package replication issues.
