Installation Guide and Release Notes

For COM objects to interoperate properly between unauthenticated COM for OpenVMS systems and Windows, perform the steps described in the following sections. This will configure the COM objects to run without security enabled on the Windows system.

A.1.1 Setting on Windows Systemwide Authentication Level

On Windows systems, set the systemwide authentication level using this procedure:

1. Run DCOMCNFG on the Windows system.
2. Select the Default Properties tab.
3. Set the Default Authentication Level to None.

After a COM application has been registered, check the security properties for that application to ensure that an unauthenticated user can activate the image.

To do this, perform the following steps:

1. Run DCOMCNFG on the Windows system.
2. Select the application by name.
3. Click the Properties button.
4. Click the Security tab.

Set the access permissions (registry value AccessPermission) so that user Everyone is allowed access (Allow access).

Set the launch permissions (registry value LaunchPermission) so that user Everyone is allowed access (Allow access).

Set the configuration permissions so that user Everyone is allowed at least Read access to the Registry values.

A.1.3 Setting on Windows Application Security Identity

After you set security permissions, you must set the identity of the account to run the application. To do this, click the Identity tab, and select Theinteractive user.
