SQL Server Installation

Hi, I am installing SQL server for the first time and I have done all the prodcedures as given in the product CD to install SQL Server for Navision. At the time of installing SQL, I gave the option to install in local computer. (should it be Remote computer) Now the server is up and running fine in my system but in the other systems I am able to see my server name but when i try to open it in ‘Microsoft SQL Server Option for MBS-Navision’, it says server was not found. I am not able to guess the reason behind it. Is it network error or SQL installion error. I read the manual for SQL installation it never mentions any such error. Thanks in Advance
