DOCUMENT:Q246391 08-MAY-2002 [iis] TITLE :PaswordChangeFlags Set to 4 or Higher Causes Access Violation PRODUCT :Internet Information Server PROD/VER:winnt:4.0 OPER/SYS: KEYWORDS:kbWinNT400PreSP7Fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== If you set the PasswordChangeFlags value to 4 or higher, and the number of days that a user's password will expire is less than the PasswordExpirePrenotifyDays value, an Access Violation error message occurs. CAUSE ===== If the PasswordChangeFlags value is set to 4 or higher, when IIS checks to see if it needs to redirect the client to the password expire page, the function IIS calls returns NULL instead of a pointer to a string containing the URL. IIS incorrectly attempts to use the pointer to check the string to see if it is empty without first checking to see if it has a valid pointer.
