check if you can ping an IP ( aka for instance).
If not, you're problem is elsewhere.
Check all relevant settings with redhat-config-network (it's on the RH9 cd's if you didn't install it).


[PS, edit]: Do you run your own DNS server? If not, call your ISP to ask for the IP's of the
nameservers if you don't already know them.

Try switching off your firewall goto terminal and typr service iptables stop, this will only deactivate service temporaraly. see if it works then we will give you work arounds.

I tryed all the above suggestion, no luck. When i ping i am getting "Destination host unreachable"

Also i tried "service iptables stop".

I can ping our local network machines and our proxy server. WHen i try out the network I am getting the followings:
HTTP 407 Proxy authentication required -The ISA server requires authorization to fulfil the request. Web proxy service denied.

TO log on to windows (XP), it's ask for the network username /passwd FOR AUTHENTICATION. Where as for Linux i am not getting the logging windows for authenticaton. MAy be its to do with that.
I can't thing of anything else I have tried all.
