Chances are this is NOT a DNS issue.  Try to PING www.cisco.com by name and
see if you get name resolution.  If you resolve the name to an address then
DNS is not at fault here.

I believe that your issue is more likely caused by an MTU problem.  PPPOE
requires 8 bytes of overhead and so your MTU now must be set to 1492 or
less.  The reason you can PING anything you want to is that your IP stack
will typically use a small transmission size for ICMP (PING) by default.
You can test this by typing "ping /?" on a Windows host to get the correct
syntax and then change the transmission size to 1500 and see if the PING
still works like it did.

Subject: ADSL - unable to reach URL's [7:50068]


I have been setting up a DSL connection for a home user, but he is currently
unable to reach ANY website. I am able to ping IP addresses of servers on
the internet and get a reply. But, neither IE nor Netscape is able to reach
a single page (via IP or Name).

The DHCP servers gives his adapter an IP address and gateway of the same
address. The subnet is a /24. He is using the PPPoE adapter and no router or
firewall exists at his site. I hardcoded the DNS server addresses to ensure
DNS name resolution, but this did not fix anything.

If you have any recommendations please reply. This should be a simple task
to complete, but obviously I am missing something.

Thanks
