    DCOMcnfg error

    When invoking dcomcnfg from the elevated command prompt on a Win10 Pro Desktop PC, the COMPUTERS folder appears but when clicked the center panel is blank. The Windows 10 HOME Laptop brings up the My Computer icon in the central area, just as the Desktop has in the past on many occasions.

    The tree at the left does list MY COMPUTER but when it is right-clicked|Refresh All Components or when clicking on COM+ Applications folder under My Computer, it throws an error. Thus, the five folders that are seen on the Laptop under COM+ Applications are not accessible on the Desktop PC: COM Explorer, COM+QC, COM+Utilities, COM+Utilities(32-bit), System Application. Items in the DCom config folder are available.

    "8004E00F com+ was unable to talk to the MS Distributed Transaction Coordinator" (which IS running in Services). There are no Event Viewer errors.

    On the Desktop PC with the error, there are three folders under My Computer: COM+ Applications, DCom Config and Distributed Transaction Coordinator. On the Laptop, where there is no error, there is an additional Running Processes folder.

    On the My Computer PROPERTIES page the Options and Default Protocols tabs are missing.

    Several system images were restored - without allowing updates, to be sure that they aren't the cause - all the way back to one made just after 1903 was installed. Even tried an 1809 image. Same behavior. Nothing has changed in BIOS, but could it be a setting there? Z390 Asus motherboard.

    Many forum-posted remedies for the error have been tried, though they seem to address a failure to bring up dcomcnfg at all, which is not the case here. None succeeds. SFC and DISM are clean.

    So the issue is with Com+ Applications. Any hints at what's going on??

    This may help to shed some light on your situation even if it isn't a 10016 error: Why Certain DCOM 10016 Events Don't Matter

    How can I assert that certain DCOM 10016 events don't matter? Because the note makes it clear that any such events that mention "application-specific settings do not grant Local Activation permission" are normal for the afore-cited Windows versions. Here's the meaty part of the Support Note that explains things completely:
