BUG: DCOMCNFG Allows Port Range Selection for Default System Protocols (201794)


The information in this article applies to:

  • Microsoft Windows NT Server 4.0
  • Microsoft Windows NT Workstation 4.0
This article was previously published under Q201794

SYMPTOMS

The Distributed Component Object Model Configuration utility (DCOMCNFG.exe) allows port range selection for application IDs (AppIDs), even if you do not select a protocol. If you do not configure a protocol at the Application level, DCOMCNFG lists Default system protocols on the Endpoint tab for the specific application. When you click Default system protocols, a Property dialog box appears, in which you can configure endpoint information for the default system protocols. DCOMCNFG should only display the Property dialog box for specific protocols configured at the Application level.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Run DCOMCNFG.
  2. Double-click an application.
  3. Click the Endpoint tab. Note that the Properties button is unavailable.
  4. On the Endpoint tab, click Default system protocols. Notice that the Property dialog box appears, even though it should not.
Even though DCOMCNFG allows you to change the port ranges for the default system protocols in the Property dialog box, DCOMCNFG does not update the information in the registry.
