Using the provided .HTR files, my users have been able to change their network passwords. Today, when you try to log into the website, all is fine unless your password needs to be changed. Then the page will not display at all. Calling any of the HTR files directly gets the same error. IE says 'Web site found. Waiting for reply...' and nothing changes.
The web server shows no error in the logs. It does show the expected 301 return code for the user redirect, but nothing else.
No configuration changes in any site on the server have been made. Changing the folder execute permissions to NONE does cause a 403 error, change back and the problems returns.
Server is IIS 5 on Windows 2000. This did work until Tuesday. The only thing I can find out that may have affected this is the "scr8_webregfix.exe" program from Crystal Decisions was run on the server to try and fix a Crystal Reports issue.
This is my main web server, so I can not restart it often.
