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. RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the
