DCOMCNFG is a Windows NT 4.0 utility that allows you to configure various DCOM-specific settings in the registry. The DCOMCNFG window has three pages: Default Security, Default Properties, and Applications.
You can use the Default Security page to specify default permissions for objects on the system. The Default Security page has three sections: Access, Launch, and Configuration. To change a section's defaults, click on the corresponding Edit Default button. These Default Security settings are stored in the registry under HKEY_LOCAL_MACHINE\Software\Microsoft\OLE
.
On the Default Properties page, you must select the Enable Distributed COM on this Computer check box if you want clients on other machines to access COM objects running on this machine. Selecting this option sets the HKEY_LOCAL_MACHINE\Software\Microsoft\OLE\EnableDCOM
value to Y
.
You change the settings for a particular object with the Applications page. Simply select the application from the list and click the Properties button. The Properties window has four pages:
RemoteServerName
value is added under the AppID for that application. Clearing the Run Application on this Computer check box renames the LocalService
