Connection problem

[Claude Jones]

Fons: Thank you for your help. I had found similar suggestions during my  
efforts to find a solution by searching the list archives. I will try this  
when I return home, tonight (machine is new home PC). The thing that was  
confusing to me was why I would have to configure DNS in KPPP when I  
didn't have to do so in the Network Device Control dialogue. In the  
latter, I simply told it to get all info from DHCP and it worked.
