How do I read the event log from ASP?
One option would be to use Windows Management Instrumentation (WMI). I added a little extra to this script: a link to eventid.net with parameters for the event ID and the source of the event (in order to provide more information about the error), as well as a search of Microsoft's Knowledge Base for articles that mention the error.
Note that you need to run this in a folder where IUSR or an authenticated user (using windows auth) has sufficient rights to read the event log. For more details about this object, see the Win32_NTLogEvent topic from the WMI SDK.
Another option would be to use a 3rd party component, such as ASPEventViewer.
If you know of other tools or methods for extracting Event Log information into an ASP page, don't be shy.
