Retrieving the COM class factory for remote component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344} from machine failed due to the following error: 800706ba

Solution

  • Windows Firewall is blocking DCOM access. Adjust your firewall to allow DCOM port mapper (RpcSs service) on TCP port 135 & allow DCOM to access IIS configuration COM objects (windows\system32\dllhost.exe).

Firewall rule for DCOM port mapper (command line)

netsh advfirewall firewall add rule name="AllowDCOMPortMapperForIISConfiguration" dir=in action=allow profile=domain protocol=tcp localport=135 service=RpcSs

Things to consider:
Add remoteip restrictions based on your network. For example, to lock down to a static ip, you would add remoteip=198.168.10.25

remoteip can be based on a subnet as well.

Firewall rule for DCOM access to IIS configuration COM objects (command line)

netsh advfirewall firewall add rule name="AHADMINAccessForIISConfiguration" dir=in action=allow profile=domain protocol=tcp program=%windir%\system32\dllhost.exe

Things to consider:
Adding remoteip restrictions to the firewall rule and restricting the AHADMIN to a specific port

  • Last option - Disable windows firewall
