Do these customers have some sort of dialup cpe, e.g. a router that dials on behalf of the LAN they are connected to?

	Let me add that this is only affecting about a couple dozen customers.
	
	If they bring their system in to our office we can dial up and surf fine.
	
	If we go out to the customers premises with our laptop sometimes it works
	and sometimes we get the same error.
	
	Customers can surf for about 10-15 minutes.  Then "page cannot be found".
	Also I can have customer ping a IP and get all replies back...I can have
	them ping www.yahoo.com and get all replies back.....but the cannot browse
	check or send email or use AOL IM or MSN IM.
	
	Also,  Everything seemed to be fine earlier this evening and now has stated
	going down hill over the last hour or so....
	
	Like I said....
	
	THIS IS DRIVING ME CRAZY!!!!!!
