远程登录到SQL Server Express 2008

我正在远程访问SQL Server Express 2008。

• 我已打开服务“SQL Server浏览器”
• 我已打开服务“SQL Server(sqlExpress)”。
• 我已启用TCP/IP,并在属性中将动态端口设置为空白,将TCP端口设置为1433。
• 我可以在本地连接(使用IP),这样我的凭证就正确了。
• 我的Windows防火墙中有一个例外记录,将1433端口设置为打开。
• 我已执行系统重新启动,使所有服务仍处于打开状态。

在我尝试通过远程计算机连接之后,我会得到这个错误。

Cannot connect to XXX.XXX.XXX.XX

===================================

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)

------------------------------
Error Number: 3
Severity: 20
State: 0

我们将非常感谢您的想法和解决方案。

编辑 你好,谢谢你的快速回复。目前没有连接字符串。我尝试使用以下方式连接: SQL Server Management Studio 2008

编辑2 嘿,尼克。 我正在使用servername\sqlexpress连接,我关闭了Windows防火墙,但仍然没有任何乐趣。

我尝试按照您的建议添加端口:
