I get an "unable to connect message" with SQL Enterprise Manager, and I know my username and password are correct. Why is this?

If you have followed Article 137 and you are getting an error similar to the one above, then you need to go configure the default protocol. Since the Internet uses TCP/IP to communicate, we need to tell SQL Enterprise Manager to use TCP/IP first before trying any others. Go to the SQL Server 2000 program group on the start bar and choose "Client Network Utility". When the program loads you will see the default protocol option on the first page.
