安装了vs2005后,安装sql2000,sql的查询分析器可以使用,但是用企业管理器时,它这样显示:
A connection could not be established to DISCOVER\SQLEXPRESS.

reason:[SQL-DMO]you must use SQL Server 2005management tools to connect to this server..

please verify SQL Server is running and check your SQL Server registration properties (by right-clicking on the DISCOVER\SQLEXPRESS node) and try again.

其中 DISCOVER 是我的计算机名.

我该怎样解决...
