Q. I installed the software, but it doesn't protect anything at all!
Probably the AuthentiX ISAPI filter is not loading. Make sure you have followed the installation instructions properly.
The main dialog of the Windows AuthentiX GUI should have a message at the top saying "The filter is loaded and running correctly".
Even so, go the MMC for IIS and right click properties and click on the Filters tab. The ISAPI filter should be loaded, and should have a green "go" arrow beside it. If you are using a time-expiry version, make sure that the software has not expired - look in the About Box, If you are using the request-limited (990) version, then perhaps the request limit has been reached - look in the About Box to check and if so, restart IISAdmin.
If none of the above apply, then far and away the most common issue is the following: You are not protecting the same directory you are accessing via the browser!
Other times you may be attempting to protect a backup or "staging" set of directories.
It is all worth checking.
IE will sometimes log you in with your current login without telling you. Try using Netscape or turn off NTCR (Integrated Windows Authentication in Windows 2000).
