Windows 2003 comes with Windows Firewall by default doesn't it? If it's
SP1, there is an applet in the Control Panel. If you don't have SP1, then
you have right-click the network connection, click Properties for TCP/IP,
and then look under the Advanced tab. (If memory serves.)

A default instance of SQL Server listens to port 1433 by default. Non-
default instances typically uses other ports. When a client connects to
a non-default instance it first interrogates on UDP port 1434 to get the
actual port number. If that service is not available, for instance because
of a firewall, you can set up alias with the actual portnumber. I think you
also can specify the port number when you connect as SERVER,1234.
Finally, you did install service pack3 or 4 for SQL 2000, didn't you?
