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. For additional information on using
IISADMPWD for password notification, click the article number below to view the
