Can't connect to web

Running IE on WinME machine (P4, 512M). After failed install of NSW 2005,
IE 6 & Outlook Express can't connect to web. I can ping my ISP gateway and
DNS servers & my time UDP packets pass through ok, other machines on my
network connect to web no problem. I am also able to connect to my router
via IE6, just can't get beyond the router except that after a long wait I
can bring up Google and once I get to Google I can navigate within Google,
but if I try to open another site I get a time out.
I tried removing and reinstalling TCP-IP, IE6, Norton and even reinstalled
ME. Nothing I've done has made any difference with my browser problems. I
don't believe the problem is with IE as MSMoney will not connect to my bank
either. I use a DSL connection but tried to connect through my modem with
the same result, the modem connects and completes the login but after the
connection is up, IE will still time out looking for a site.
I would sure appreciate any and all suggestions that may address my problem.

Thanks
Barry
