Windows Administrator cannot access Component Services: DCOM

In this article, we will discuss how to configure DCOM (Distributed COM) when an administrator (or other members of the administrators group) cannot edit configurations in Component Services.

Understanding DCOM

DCOM is a technology that allows COM objects to be used across network boundaries. It enables applications to communicate with each other even when they are running on different machines.

The Problem: Administrator Cannot Edit Configurations in Component Services

Sometimes, an administrator may encounter issues where they cannot edit configurations in Component Services. This can be a frustrating problem, as it prevents the administrator from configuring DCOM as needed.

The Solution: Configuring DCOM Manually

If an administrator cannot edit configurations in Component Services, they can configure DCOM manually. Here's a step-by-step guide:

1. Open Registry Editor. You can do this by typing regedit in the Run dialog box (Win + R).

2. Navigate to the following registry key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<Component Name>\DCOM Config\<Object ID>

   Replace <Component Name> with the name of the component you want to configure, and <Object ID> with the object ID of the COM object.

3. In the right pane, double-click on the Default Properties key.

4. In the Edit DWORD Value dialog box, set the Access Permissions value to the desired level. The possible values are:

   • Access denied: No one can access the object.
   • Local access only: Only local users can access the object.
   • Local and remote access: Both local and remote users can access the object.
   • Remote access: Only remote users can access the object.

5. Click OK to save the changes.

6. Repeat steps 2-5 for each user or group that needs access to the COM object.

Additional Tips

• To find the object ID of a COM object, you can use the regsvr32 command in the Command Prompt. For example:

  regsvr32 /n /i <DLL file>
  

• If you're not sure about the component name or the object ID, you can use the Component Services snap-in to find them. Here's how:

  1. Open the Component Services snap-in. You can do this by typing dcomcnfg in the Run dialog box (Win + R).

  2. In the Component Services window, expand Computers and then My Computer.

  3. Right-click on DCOM Config, and then click on Default Properties.

  4. In the Default Properties dialog box, click on the Security tab.

  5. Here, you can see the component name and the object ID.
