Stop DCOM Error 10021 in 7 Simple Steps

If you use DCOM to enable the remote execution of COM objects, you might have encountered DCOM error 10021. Here's how to correct that error:

  1. Log on to the computer using an Administrator account.
  2. Select Run on the Start menu and type dcomcnfg.
  3. In the Microsoft Management Console (MMC) Component Services snap-in that appears, navigate to Console Root, Component Services, Computers, My Computer, DCOM Config, Framework service in the left pane.
  4. Highlight Framework service, right-click it, and select Properties.
  5. Select the Security tab.
  6. Under Launch and Activation Permissions, select the Use Default radio button and click OK. (Launch and Activation Permissions is set to Customize by default.)
  7. Close the Component Services snap-in and log off.

Before implementing these steps, I was getting four DCOM errors per logon. Now I don't get any.
