[Web4lib] Hotmail and 'Page cannot be displayed' message

[Chadwick, John, DCA]

Here is a good article about Hotmail and Messenger. Hotmail users
authenticate with Messenger on port 1863. With port 1863 blocked,
Hotmail users have problems authenticating.

I don't know about saying that "Hotmail won't work without Microsoft
Messenger."  It should - Hotmail is just a website, and it would be
running over port 80.
I would also suspect a firewall issue, but one that blocks access to
"http://www.hotmail.com" instead of a certain port.  It sounds like you
are using different routes to the Internet for different PC's, so have a
look "upstream" from the PC's that are having the problems.  My guess is
that you may find an overzealous admin who blocked Hotmail and Yahoo.

A good way to test if it's the encryption is to find someone with a
gmail account.  I know you can access gmail, both encrypted and
non-encrypted, simply by changing the "http://" to "https://".

Cheers,
Andrew

It is most likely a firewall issue. We block Microsoft Messenger, both
at the firewall level (port 1863) and application level in active
directory. Hotmail will not work without Microsoft Messenger. Messenger
is very prone to virus attacks and sucks down bandwidth.

Sounds like a firewall issue.  Are the PCs that can't get mail at the
same location?  If so, I'd check the firewall settings and see if the
incoming mail ports are being blocked (port 110?).
