跨域运行来自C＃应用程序的SQL脚本

Question

To run sql script files from my C# application, I referred this. http://social.msdn.microsoft.com/Forums/en/adodotnetdataproviders/thread/43e8bc3a-1132-453b-b950-09427e970f31

it works perfectly when my machine and DB server are in the same domain. my problem now is, i'm executing this console application from a machine (name: X, user id: abc, domain D1). the SQL server is in another machine (name: Y, domain: D2). I use VPN to connect to machine Y with user id 'abc' and work on SQL in remote desktop. how can i run sql scripts across domains? I use this in a custom activity in my TFS build template as the last step to run the scripts in the target database which is in domain D2.

i'm getting this error: "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)"

is it possible to connect to the DB using the admin user ID of machine Y in domain D2?

问题不在于您位于不同的域，这可能是另一端SQL服务器上的配置问题 - 可能未配置为允许远程SQL连接和/或SQL服务器身份验证 - 或者您只是可以由于某种网络问题而连接到服务器 - 例如，防火墙位于中间 - 一旦确定哪个是问题，您应该能够按照链接的帖子所述运行SQL脚本。

This is not a user credential issue. You'd be getting a different error. It seems as though your client machine can't actually access the server\\instance.

Try pinging the server. If you get a response, then I'd look at a few other things. First off, if this is a named instance, then you need to ensure the SQL Server Browser service is started. Also make sure the protocols for the SQL Server service has TCP/IP enabled. When you are on the local machine connecting to the instance, you utilize Shared Memory. But remotely it utilizes (or tries to use) TCP/IP.

Let me know where you're at after those things are checked.

如果目标SQL Server可以设置为混合身份验证模式，则可以连接到特定的SQL Server UID和PWD帐户而不是网络帐户，而不是作为管理员帐户连接，您的问题将得到解决。
