Now I am back on my own computer the following error has occured, I have looked at general help for this error and tried the help given but it hasn''t worked, any idea on what could have gone wrong, thanks in advance.


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)

推荐答案

如果SQL Server的实例名称不正确，则会发生上述错误与connection string.
中给出的名称匹配 运行SQL Server Management Studio，在连接服务器"表单中检查Server name，然后用该名称替换connection string中的服务器名称.

The above error occurs if the instance name of the SQL Server does not match the name given in the connection string.
Run the SQL Server Management Studio, check the Server name in the connect to server form and replace the server name in the connection string with this name.
