无法连接到SQL Server 2008的本地实例

Question

I'm attempting to connect to an instance of SQL Server 2008 (Developer Edition) in SQL Server Management Studio but am receiving the following error:

In SQL Server Configuraton Manager, all services are running and logged in as LocalSystem.

I have set the SQL Native client 10.0 configutarion to enable Shared Memory, TCP/IP, and Named Pipes. I have also set SQL Serer Network Configuration to enable Shared Memory.

Answer 1

The default (unnamed) instance uses MSSQLSERVER as its service name - so it seems your instance is actually called MSSQLSERVER08 .

Therefore, you need to use

.\MSSQLSERVER08

or

(local)\MSSQLSERVER08

as your server name for connecting...

Note:

all these things refer to the local machine in the context of connecting to a SQL Server installed on that machine:

• .
• (local)
• localhost
• or your actual machine name (whatever it might be)

Answer 2

For SQL Express use .\\MSSQLSERVER08 as your server name. Try to enable TCP/IP, Shared Memory and Named Pipes from all programs

Also check if the service is started:

Answer 3

Restart the SQL Server services. Then try to connect.

OR

If you have Installed SQL server with named instance, browse for for the server name.
