If there are no firewalls on your network, try temporarily disabling the firewall apps (including Windows Defender Firewall with Advanced Security ) on the client and server-side and check the RPC connection. Or you can run the Service management console (services.msc) and make sure that the Remote Procedure Call (RPC) and DCOM Server Process Launcher services are in the running state and configured to start automatically.Īccess to the remote computer over RPC ports may be blocked by firewalls (this is a very common reason).If the services are stopped, run them with the command: net start rpcss & net start Winmgmt If these services are started, the commands should return STATE: 4 RUNNING. You can check the status of services using the following commands: sc query Winmgmt and sc query rpcss. Verify that Remote Procedure Call (RPC) and Windows Management Instrumentation services are running on the remote computer.Check if you have entered the correct IP address or computer name check if the remote computer is not in the shutdown/startup state now.Now you need to check the next things in order to fix the error The RPC server is unavailable 0x800706BA: Use the following command: netstat -ano | find "135" The Dynamic RPC range is blocked by firewalls installed between your computer and the remote computer.įirst of all, make sure RPC Endpoint Mapper port 135 in listening on a remote computer.The RPC Endpoint Mapper port TCP/135 is not accessible on the remote computer.The RPC service is stopped/failed on the remote computer.Several common problems can cause the RPC server unavailable error: If the RPC communication between your hosts is working fine, you should get the remote computer info in the command output: In this example, you can see that the remote computer is not accessible by RPC. + FullyQualifiedErrorId : GetWMICOMException, + CategoryInfo : InvalidOperation: (:), COMException + Get-WmiObject Win32_ComputerSystem –ComputerName 192.168.0.14 Get-WmiObject : The RPC server is unavailable. Is anyone else seeing this behavior with the pending DCOM update?įirst time posting here and really just trying to see if this is on MS's radar at all.PS C:\Windows\system32> Get-WmiObject Win32_ComputerSystem –ComputerName 192.168.0.14 They have mixed OS's for DCs and are only seeing the issue on 2019 ( ). I found one reference to someone else encountering the same.

Our only solution has been to roll back the patch on our DC.

Having read up on Microsoft's transition to a minimum of Packet Integrity for DCOM authentication (see June's KB5004442 and the DCOM issue described in CVE-2021-26414), it would appear that, at least in Server 2019, this feature has been enabled prematurely (Supposed to be Q1 2022 based on the timeline in the KB5004442) and the described reg entry to temporarily bypass the DCOM update does not work (it is supposed to be valid all of 2022 after the feature is enabled). After applying, we started receiving many DCOM error events 10036 (Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application) for a user id function on our Palo Alto FW (It uses a service account to resolve user identification from AD). We recent applied KB5005568 (Sept 21 update) to one of our Server 2019 DCs.
