c# - 部署期间定位服务器 26 的 IIS 8.5 SQL 错误

Question

当尝试在本地计算机上使用 IIS 将项目部署到网站时，我收到 SQL 网络接口(interface)错误 26(详细错误如下)。

尝试部署 sensenet按照其 guide 中的说明从 zip 文件中获取.

我一直在使用 MSDN、Stack 和 Code Project 上找到的在线建议来解决问题，但到目前为止还没有任何效果。

我也禁用了 Windows 防火墙和第三方防火墙。我使用的端口是 8081(8080 由我的 IIS 上的工作网站占用)，我还检查了 SQL 服务是否正在运行。 TCP/IP 也按照 this 启用方法。

我正在尝试使用SenseNet提供的安装zip中的脚本创建一个新的数据库。

我正在使用 IIS 8.5、Web 部署 5 和 SQL Management Studio 2012。

对于可能导致此错误的原因，有人有任何其他建议吗？

谢谢

检查 web.config 文件:查找 SQL 连接字符串并查看在安装过程中添加的用户名和密码(不应该是“sa”用户，而是像“sensenet6”这样的自定义帐户)。该用户应该有权访问也添加到连接字符串中的数据库。以下是可能有用的论坛主题:http://forum.sensenet.com/viewtopic.php?f=3&t=7279&p=10803&hilit=404&sid=c79596c733ccd9b721
