Outlook no longer responsive since XP Pro repair

[RSG]

Greetings list,

Recently, I had to do a repair with XP Pro on my machine.
The first problem I had was the loss of my connection
PPPoe information and when I tried to redo the
connection, buttons were greyed out. After spending some
time on the phone, this problem was fixed and I can
connect to the internet through my DSL line now.

However, now when I try to run Outlook, I either get that
the server could not be found, your login information is
incorrect, or you are not connected to the internet (yet
I can ping the exchange server that has all my email).

So, anyone have ANY ideas what to do. Using Outlook web
access just does not work (nor can I archive or access
contact lists as well).

Thanks!
