Hello Xavier Roche,
   Thank you for your info. When I tried to search 
connection under help of win2000. I have found something 
switch.inf winnt\system32\ras and edit the switch.inf with 
my username & password filled into the file.
   But I do not know hot to activate or execute the 
connection to dialup to my broadband ISP automatically.
   Could you enlighten me again !

Thanks !
Bruce
