The Events.asp URL machine setting should be configured correctly. This is the URL that will be passed to the Description area in the Event Properties dialog box. Change this value if you want to use a different Web server to handle event information requests. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Event Viewer\Events.asp URL (2) KEY: HKLM\Software\Policies\Microsoft\EventViewer\MicrosoftRedirectionURL
