DOCUMENT:Q265445 08-MAY-2002 [iis] TITLE :Password Notification Hangs Handling Multiple Password Expiratio PRODUCT :Internet Information Server PROD/VER::4.0,5.0 OPER/SYS: KEYWORDS:kbWin2000SP2Fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server version 4.0 - Microsoft Internet Information Services version 5.0 ------------------------------------------------------------------------------- SYMPTOMS ======== IIS may stop responding when it is handling multiple, simultaneous password expiration notifications from the same client using the IISADMPWD virtual server. CAUSE ===== IIS 4.0 and 5.0 use a password cache list to keep track of current users when processing password changes. The cache has a list traversing problem where it does not crawl the cache correctly after the first entry, and often crawls a series of invalid addresses when trying to find a user or password in the cache, which makes it appear to stop responding. WORKAROUND ========== Use ADSI for password notification.
