PRB: Run-time error -2147023071 (80070721) using WithEvents

ID: Q171456

The information in this article applies to:

Microsoft Visual Basic Control Creation, Learning, Professional, and Enterprise Editions for Windows, versions 5.0, 6.0

SYMPTOMS

When using an ActiveX component that defines events, you may receive the following error when this component is accessed via DCOM.

Run-time error -2147023071 (80070721)
Automation Error

This error does not occur if the ActiveX component is used locally or if the client does not instantiate the remote object using the WithEvents statement.

CAUSE

The cause of this behavior is the configuration of the DCOM Server's security options.

RESOLUTION

To fix this problem, the security options for the Microsoft Windows NT DCOM server must be set appropriately. To make these changes, follow the steps below:

NOTE: This procedure requires administrative access to the Microsoft Windows NT system that is active as the DCOM server.

Install the Server and the Client components as per the installation instructions. This will register the components on the appropriate systems.

On the system that is to act as the DCOM server, click Run from the Start menu. In the Open field, type "DCOMCNFG.EXE" (without quotes). Click OK.

Select the ProgID or GUID that represents the component you wish to configure. Click Properties.

In the Identity section, select 'The Interactive User' option.

Change the other security options to their desired settings.
