[英]Cannot connect to SQL Server 2008 R2 Express Instance on the Network
I installed an instance of SQL Server 2008 R2 Express on my 32 bit Windows 7 machine. 我在32位Windows 7计算机上安装了SQL Server 2008 R2 Express实例。 I can see it and connect to it with SQL Server Management Studio locally but not on the network. 我可以看到它并使用SQL Server Management Studio在本地(但不在网络上)连接它。

The Firewall is turned off for testing 防火墙已关闭以进行测试
When I try to see this instance with a command prompt (sqlcmd -L) from another computer I get a list of network servers. 当我尝试从另一台计算机通过命令提示符(sqlcmd -L)查看该实例时,我会获得网络服务器列表。 Sometimes it shows up and sometimes it doesn't. 有时会出现,有时却不会。 If it shows up I still can't seem to connect and the error message number is 26. If feels like there is some switch somewhere that needs to be turned on. 如果显示出来,我似乎仍然无法连接,错误消息号为26。如果感觉有一些开关需要打开。
I am leaving this up there for any other users who have mental blocks occasionally... I had not turned off all the firewalls. 我将其留给其他偶尔遇到精神障碍的用户使用...我没有关闭所有防火墙。 In windows7 you have three different firewalls and you have to turn off the right one 在Windows7中,您有三种不同的防火墙,您必须关闭正确的防火墙
