Trying to set up a new ADSL network connection using a subnet mask of 255.255.255.240 returns an error that the submask "Is not valid". This is was via the settings Network and Dial Up Connections. On a Workstation Windows 2000 it was possible to set up a connection using the non standard subnet mask. What is need on the Windows 2000 server ?
