I've got a really knotty problem with Vista, I'm hoping someone has a clue
how to fix it.
First of all, the environment is all standard Microsoft, there is a URL
blocker but I have determined this has nothing to do with it by turning it
off completely, plus it's not a firewall problem, all ports are open. Most
importantly, all of the XP and 2003 machines on the network have IE7 and DO
NOT exhibit this problem and appear to work perfectly normally.
When I start up Live Messenger, I get extended error code 80048418. This
means nothing to me, the only references I can find are to SSL problems.
When I log the connection string, the log reports problems communicating on
port 443, but it appears to be able to connect on port 443. The diagnostic
tool says it can find the server no problem. All the 2003 and XP boxes on
the domain don't have a problem.
When I go into IE, all https sites come up with a certificate error, "The
security certificate presented by this website was not issued by a trusted
certificate authority". I've tried installing the certificates in the
trusted certificate authority store, it has no effect. Once again, doesn't
happen in IE7 on any of the non-Vista machines.
Bear in mind we have several Vista Business machines, they all have the same
problem. I tried installing Vista as a standalone installation, that machine
does not exhibit the problem.
This made me think it must be something in the GPO, but all the SSL settings
are default, and all the 2003 and XP machines are subject to the same GPO
anyway.
The only thing I can think of is that there is some weird difference in the
registry, but I'm stumped at this point.
