Event ID 10016 - DCOM Permissions Error

I'm having trouble trying to figure out how to correct a persistent Event ID 10016 error that keeps showing up in Event Viewer.

I've actually found a couple of guides on how to fix this...change the launch permissions for the app that's causing the problem (IPbusEnum) but when I try to change the launch permissions using dcomcnfg none of the options on the properties/securities tab are available (grayed out).

My user has administrator permissions, I've tried launching dcomcnfg.exe by right click/click on "run as administrator" but no go.

Here's the text of the error message:

The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID

{C97FCC79-E628-407D-AE68-A06AD6D8B4D1}

and APPID

{344ED43D-D086-4961-86A6-1106F4ACAD9B}

to the user NT AUTHORITYSYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

The CLSID and APPID resolve to a service run under svchost (IPBusEnum). Would appreciate any pointers/hints on how to resolve this error.
