Windows 2008 R2企业版问题（消息：System.Web.Services.Protocols.SoapException：服务器无法处理请求）

Question

嗨，我在Windows 2008 R2企业版上面临以下问题，但是在Windows 2008 R2标准版上很好。

问题： .Net Windows服务称为Web服务。 Web服务抛出以下错误。

错误信息：

System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Data.SqlClient.SqlException: 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

在代码中的某处，您正在连接到sql服务器，并且无法建立连接。

您是否指向错误的sql服务器（也许是开发机器？），或者两者之间没有物理连接，即应用程序服务器和sql服务器。
