When our users try to get Windowsupdate from Windows XP, they get "error
0x80244021". It is one of the two errors described in this article:
http://support.microsoft.com/default...b;en-us;885819
The problem happens because they are going through an authenticating proxy
that lies on a different domain than they reside on.
Version 4 windowsupdate did not have this problem, because at the right
moment it would prompt them for their authentication credentials and they
could enter their username and password for the other domain. Either that, or
it would use their cached credentials for that session and it would all work.
Version 5 windowsupdate has the problem because, when the proxy server
prompts the windowsupdate software for credentials, the windowsupdate
software doesn't prompt the user for their password, and does not use their
cached credentials. Thus, windowsupdate fails.
The corporate overlords that control the proxy server will not allow
anonymous connections. So, at the moment:
MY USERS CANNOT GET WINDOWSUPDATE, HAVE BEEN UNABLE TO DO SO FOR MONTHS, AND
CANNOT PROTECT THEIR COMPUTERS AGAINST MICROSOFT SECURITY BUGS NOW.
Microsoft: Please please please please fix windowsupdate to start working
through proxy servers again. Please.
