<div dir="ltr">my ISP is giving internet Access with DHCP based IP. so , to get internet i have to wait till i get their Assigned IP. and then i have to open log in page, and type in user name and password to use internet. if i don't get their assigned IP or If i can't sign in successfully coz of their bad connection, i can't totally use internet. so , for the time being, I m providing internet access with Proxy server (Microsoft ISA server) to all my XP clients. even with ISA server, i have to manually log in every time in the morning or every time i lost my DHCP ip and get again, sign in to enter credentials ISP gave. So , for the time being, I m very enthusiastic to use Ubuntu. and I would like to switch to Hardy Heron, and replace my ISA. Can Ubuntu reduce my daily doggone manual steps?? I would also like to set download limit of users by means of IP address. all my clients are XP and they have manaully configured IP addresses. thanks -- Nay Myo </div>
