    DISTRIBUTEDCOM Event error 10016


    Recently for some reason the Laptop has been slow in booting to Desktop ready for use although very limited items are in Task Manager, StartUp

    Looked in event viewer and shows a repetitive error over 3 times.

    DistributedCOM event error 10016

    When searching the registry for the clsid. Comes up as ShellServiceHost.

    When following instructions to add parameters and allow etc in Component Services, ShellServicesHost, Security, Launch and Activation Permissions, Edit.

    Add is greyed out not allowing any change despite running as Administrator.

    Prior to this I ran
    DISM /Online /Cleanup-Image /RestoreHealth and sfc /scannow saying some errors had been found and sorted. But still the slow boot.

    Any Ideas if this the cause of slow startup etc.

    1. Please type Regedit into Start Menu.
    2. Go to HKEY_Classes_Root\CLSID\*CLSID*.

    Note: *CLSID* stand for the ID that appears in your event viewer error.

    3. Right click on it then select Permission.
    4. Click Advance and change the owner to Administrators. Also click the box that will appear below the owner line.
    5. Click Apply and grant full control to Administrators.
    6. Close the tab then go to HKEY_Local_Machine\Software\Classes\AppID\*APPID*.

    Note: *AppID* is the ID that appears in your event viewer.

    7. Right click on it then select Permission.
    8. Click Advance and change the owner to Administrators.
    9. Click the box that will appear below the owner line.
    10. Click Apply and grant full control to Administrators.
    11. Close all tabs and go to Control Panel --> Administrative Tools.
    12. Open Component Services.
    13. Click Computer, click My computer, then click DCOM Config.
    14. Look for the corresponding service that appears on the error viewer.

    Note: For this step, look for the one that appeared at the right panel of the RegEdit. For example, the AppID {4839DDB7-58C2-48F5-8283-E1D1807D0D7D} registry key contains the "ShellServiceHost" data with a (Default) as a value name. Now look for "ShellServiceHost".

    15. Right click on it then click Properties.
    16. Click Security tab then click Customize in the Launch and Activation permissions section. Click Edit. Click Add. Add a Local Service. Then Apply.
    17. Tick the Local Activation box.

    Thanks,

    Done as listed, but in Launch and Activated permissions. 'Add' is still greyed and cannot add anything.

    In the Permissions for Administrators box below the Local Launch, Remote Launch, Local Activation and Remote Activation are all marked as 'Allowed'. ??

    Please go over the instructions again the Add button grayed out because of wrong permission setting at registry.

    OK will do,

    But looking back to find a system restore point, found a restore point as 'Windows Module Installer' approx 5 entries, same day all within 10 mins of each. This approx is where the startup has been noted to be slow.

    Would this be associated with the event error. ??

    All of your steps are good, except that you forgot to note at step #11 that after closing all tabs, a reboot is required before any of the steps will take or have an effect. After the reboot, the boxes are no longer greyed out and one can continue to add the Local Service and then tick the Local Activation Box. Or possibly if the Component Services were already open, close the Component Services and reopen them to see if the boxes are still greyed out - if they are, a reboot is absolutely necessary.

    I tried it first without a reboot and when I clicked "Edit" in the Component Services of the affected App ID, a strange box appeared that stated callback parameters for inheritances on said key needed to be removed in order to continue.

    I backed out of it all by canceling and rebooted instead. After the reboot, everything went fine although I did still have to click "remove" for the callback parameters for inheritances on said key in order to add the Local Service.

    Something new I haven't seen before after editing permissions and just wanted to share my experience with it.

    You're Welcome!

    I can't recall before if the reboot was necessary - I think it use to work without a reboot before; but now with this callback parameter thing that pops up about inheritances of the key in question before adding a Local Service, I think reboots are a better idea to be safe.

    OK Guys,

    I've been over and over the instructions and cannot get to as below.

    "15. Right click on it then click Properties.
    16. Click Security tab then click Customize in the Launch and Activation permissions section. Click Edit. Click Add. Add a Local Service. Then Apply.
    17. Tick the Local Activation box."

    Add is constantly greyed out.

    You did see my above post about rebooting after step 10 right?
    Then you proceed with the rest of the steps.
