I have two SQL Server installations. One on a Window NT 4.0 server and the other on a Windows 98 machine (which is networked to the NT server.) In SEM on the Windows 98 machine machine I am able to register and see the SQL Server on the NT box, but not vice versa (cannot register the Window 98 SQL Server on the NT SEM. I get the following error when attempting to do so:"A connection could not be established to - Access denied. ConnectionOpen(CreateFile(). Please verify SQL Server is running and check your SQL Server registration properties and try again.) Would you be able to point out my error and steps I should take to solve this problem on my own in the future. Thank You.
