I recently took over IT duties for a small Doctors office with a T1 and 50 IP's (no kidding). I have installed a 2003 Server and I want to change them to a private IP scheme and free most of those others they are paying for. I do not have the password to the Cisco 1721 that is setup for the T1. They are also setting up offsite locations so I will need to also set up a VPN.
I have read the fix for reseting the password but i am curious if that changes the settings? They currently do all of thier billing and scheduling off site so they can't be down. What do i need to know to set up a T1 connection if I reset the router? I appreciate any help.
