DCOM does not always work as expected, as there may still be some errors. One of them is error 1084, which interrupts the execution of programs on a computer remote from the network. The DCOM 1084 error in Windows 10 usually occurs when your PC freezes completely and has to shut down by force. For many users, the PC continues to load and hangs at first with the point circle. However, only a small number of them complain about having an error in the graphics of the screen.

Check the Status of the DCOM Server Process Launcher

The DCOMLAUNCH service starts the COM and DCOM servers in response to object activation requests. If this service is stopped or disabled, programs with COM or DCOM will not work properly. It is strongly recommended to use the DCOMLAUNCH service.

  • Search for services in the Cortana search box, click on the Services icon, then open the Service Manager in a new window. Or simply press the WINKEY + R key combination to start the Run window.
  • Type services.msc and press Enter to open the same utility.
    For the following services:
    DCOM service process launcher.
    Basic tasks of infrastructure services.
    Local session manager.
    Remote procedure call (RPC).
  • Click on it one after the other with the right mouse button.
  • Click on Properties. Select Automatic from the Start-up Type drop-down list. And make sure they all run.
  • Click OK for each of them.

Troubleshoot Error in a Clean Boot State


There are cases where some contradictory programs installed on your computer are the ones that cause the DCOM 1084 error. To determine which program is causing the problem, you must put your computer in a clean boot state.

  1. Log in to your PC as an administrator.
  2. Type msconfig in the Startup Search field to open the System Configuration utility.
  3. From there, go to the General tab and click on “Selective Start”.
  4. Uncheck the “Load boot items” box and make sure that the “Load System Services” and “Use Original boot configuration” options are enabled.
  5. Then click on the Services tab and select the Hide all Microsoft services check box.
  6. Click on Disable All.
  7. Click Apply/OK and restart your PC. (This will move your PC to a Clean Boot state. And to configure Windows to use the usual startup, simply cancel the changes.)
  8. From there, you can isolate the problem by checking which of the programs you have recently installed is causing the problem.
