You have encountered a "feature" of NT and Windows 2000. When you make a connection via dial-up networking, the local routing table of the machine is changed to make the dial-up connection the default gateway. You can verify this using the Route Print command from a console session.
This is a long answer, so I will break it into two parts. Here is a listing before making a dial-up connection:C:>route print =========================================================================== Interface List 0x1 ...........................
