I have 3 computer attached to an ADSL router, two of the computers work fine but on the third I cannot connect to the net or even the router.
I can ping internet address
It resolves DNS names
I have loaded firefox and it has the same problem
I have flushed the dns
I have tried to go to websites using IP address
I have disabled all firewalls and virus protection
The computer can send and receive email
I have changed DNS server address in TCP/IP address properties as well as setting them to auto.
Windows XP SP3 with IE7 and now firefox.
Any ideas would be apprciated
