MORE INFORMATION ================ You can do this by setting the PasswordCacheTTL property to zero (0). By default, Internet Information Server will cache the anonymous user account for 10 minutes. To change the PasswordCacheTTL value to zero (0), type the following at the command line: adsutil set w3svc/1/PasswordCacheTTL "0" The following sample code can be called from Visual Basic, ASP, and Windows Script Host with minimal changes in each environment: Dim oServer Set oServer = GetObject("IIS://LocalHost/W3SVC") oServer.PasswordCacheTTL = 0 oServer.SetInfo Set oServer = Nothing Please note: This procedure affects all Web server instances and decreases server performance; it is intended for debugging purposes only.
