Connecting VIA IP Address

When I try to connect via IP to a newly created Active Active cluster I
have to add the port to the IP for it to work. An example is if my IP
is 10.0.0.1 and I try to connect it times out. if I try 10.0.0.1,1433
then it works fine. Am I missing a setting somewhere to make this work
just by using the IP? Oh... and just to note this work the same accross
the network or if I am logged on local to the box.
thanks
Chris
I should have stated this but I am using SQL Server 2000 and the server
is Windows 2003
