In Vista programs fail to connect to network but IE7 works every t

[Steve]

When launching various different programs, Windows Live Mail, Quicken, Some
MS installs etc fail to connect to network stating some wording similar to
"you must connect to the Internet first or an Internet connection does not
exist." If I click retry three or four times the program will usually
connect. If IE7 is opened IE7 will work each time without error, and
browsing is normal. Opening IE7 then trying to connect on one of these
programs doesn't help. The computer also has XP on it and if I am in XP,
these same programs work flawlessly. Quicken for example is the 2008 version.
I installed Windows Live Mail last night and it is doing the same failure to
connect two or three times then it connects. I have reset IE7 as the default
browser, the firewall is turned off, I have turned off AVG, TCP V6 has been
disabled, I've hard coded the IP and DNS etc, run as admin, made my self
admin, turned off the user account control, nothing has solved this problem.
Has anyone seen this and come up with a solution. FYI - I work as a network
admin for about 1500 computers and this one has me stumped. Especially as it
is my own computer running Vista Ultimate.

What about latest Vista Drivers for the Network Adaptor in the Vista OS?

Thanks Nick - good suggestion. Unfortunately the only drivers available are
the Vista ones due to it being a Nvidia set that the only drivers available
are Microsoft. I've seen this issue on many posts with other NICS. Something
is sometimes blocking the applications like Windows Live Mail, Windows
Updater, Quicken etc from seeing the Internet yet IE7 connects everytime as
does Ping etc. The issue can occur right after boot or one time it will work
fine and 30 seconds later it will fail and say no network is available. It
can work 10 times in a row or fail ten times in a row, or work every other
time.

I might add, other computers on the Server 2003 domain / wired network / DSL
have no errors, and this same computer works 100% fine rock solid in XP. It
has something to do with how Vista works.

Hi Joel - I will check to see if JAVA is installed. However it does work 25%
of the time and fails 75% of the time. The firewall is turned off, security
features are turned off. Even when it is staying the there is no internet, I
can be on the Internet browsing. I tried to install MS Live Mail the other
night. It downloaded fine and then when launched said it couldn't install
because there was no Internet connection. The weird things is that I can be
running a Ping -t which is connecting the whole time an application is saying
there is no connection.

Apparently this is not resolveable as MS has been working on the issue since
2006. There are hundreds of posts that I found in 5 minutes with the same
type issues. They can ping, dns, work from the Internet Browser but
applications fail to connect in Vista. Every post involving MS deadended with
no solution. The answer is clear to me. Give up on Microsoft and recomend to
my clients to prepare to migrate when they can. Just google "vista
applications internet connection problems"
