This is the first time we are working with named instances on sql 2k. Every time you create a new instance, do you need to manually go in & specify the port number as 1433 on the client side?
Our clients are not able to connect to this server. They get a server does not exist or access denied message. However if In the "Client Configuration" set up under "Connection Parameters", we CLEAR the "dynamically determine port" check box in order to set the port manually and type "1433" in the port number box, it seems to work & the clients can connect.
Is this an issue with instances or are we doing something wrong?

Thanks!
