Question 1: Is it possible to change the Netmask of the primary Windows
domain controller without hosing up AD, Terminal Server, or SQL Server?

Question 2: On Windows 2k3 Server PDC is it possible to change the
domain name without hosing up the entire system? (The way they set up
the system it uses BusinessName.local and they want it to reflect the
organizations domain I know you can change the domain
name on a windows 2003 server, but I'm not sure how big a disaster it is.)
