推荐答案

p>我通常忘记的是，即使您在SQLServerNetwork-> MSSQLServer的协议中将tcp标记为启用，您仍然需要去为服务器启用可能不同的IP地址。即使具有单个NIC的服务器也将具有多管道IP地址。

The thing I usually forget is that even if you mark tcp as enabled in SQLServerNetwork->Protocols for MSSQLServer, you still need to go and enable the potentially different IP addresses for your server. Even a server with a single NIC will have multipe IP addresses.

1. 单击上面列出的MSSQLServer协议。


2. TCP / IP。


3. 现在双击TCP / IP以获取对话窗口。


4. 如果要监听所有IP地址服务器在第一个协议选项卡上的
   全部侦听框中选择是;否则


5. 选择IP地址选项卡并通过将启用
   设置为是启用所需的IP地址。

1. Click on the Protocols for MSSQLServer as listed above.
2. Then in the right hand pane enable TCP/IP.
3. Now double click TCP/IP to get a dialog window.
4. If you want to listen on all the IP addresses for the server Select Yes in the Listen All box on the first Protocol tab; otherwise
5. Select the IP Addresses tab and enable the desired IP addresses by setting Enabled to Yes.
