Request.ServerVariables(‘LOGON_USER’) always returns empty string in Framework 1.1 . Why? It worked fine in ASP

If Request.ServerVariables(‘LOGON_USER’) is returning an empty string, the problem is probably that your app allows anonymous users.

To change this:

• Open IIS manager
• right-click on your app name and choose properties
• Click on directory security tab
• Edit Authentication and Access Control
• Uncheck ’Enable anonymous’.
