There is no menu choice to create a new database diagram

[DangerDev]

Hi,
I want to create a DataBase Diagram using MS SQL Server Management Studio 2005.
But on context menu of DataBase Diagrams Folder, I am not able to see New Database Diagram menu item for any of the Database.
I am getting only two menu item "Working with Sql server 2000 Diagrams" and "Refresh".

Please post suggestions and answers.
Thanks in advance.

Problem is solved.
I was using MSSQL server 2000,
MS SQL Server Management Studio 2005 cant create diagram with it, you have to use MS SQL Enterprize manager 2000 for that.
