Client Automation - All versions.


SCCM job tries to connect using WMI to \\sccm_server\root\SMS

But WMI connection fails with error 800706BA
Error 800706BA means "RPC Server Is Unavailable"

This could have multiple cause.
A possible cause is that a port is blocked by a firewall.



RPC is using following ports :

- TCP 135 (to target machine - SCCM server)
- A dynamic TCP port. Default Range on Windows 49152-65535

Make sure these ports are allowed by firewall


Additional Information

To limit the dynamic TCP port ranged used by RPC, this could be done on SCCM/SMS Microsoft Server :

- Execute regedit and In registry 
Add the Internet key under: HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc
- Under the Internet key, add the values "Ports" (MULTI_SZ), "PortsInternetAvailable" (REG_SZ), and "UseInternetPorts" (REG_SZ).

For example, the new registry key appears as follows:
Ports: REG_MULTI_SZ: 5000-5100
PortsInternetAvailable: REG_SZ: Y
UseInternetPorts: REG_SZ: Y
- Reboot the server
- Then allow in firewall the TCP IP range set (ex: 5000-5100)
