No access, Firewall problem?

[Jonathan]

This is probably a very common problem and one that has a very straight
forward solution, but I'm afraid that my geek-qualities are in other,
non-windows fields, why I am totally unable to solve it myself.

Running windows XP and connected with a BT Voyager router.

Until recently no problems, but now:

- Router has power, ethernet and dsl
- Network connections says connected and has packages coming both in
and out
- Yet I still can't access the internet (Explorer) and get errors when
trying to send/receive in Outlook

When I restart computer and router I get a connection for a short while
before it goes out the window(s) again...
Same happens if I try to make a new connection.

I am of course thinking Firewall, since I appear to have a connection
(according to network connections). So I tried to disable the windows
firewall, but I couldn't since it said that these settings were under a
"group setting". Anyway; I am not to keen about disabling a firewall
since it is supposed to be some sort of protection.

Anyone who can shed any light on the matter????


Cheers,
Jonathan

Since I'm not at the computer at the moment, apparently I got two bits
mixed up:

- It's of course due to "Group Policies" in the Firewall menu that I'm
unable to change the setting for the firewall and not "Group Settings".

- The firewall is actually off!!!!! So now I have no idea....
