推荐答案

Hello，

您可以检查以下几点:

-检查在应用程序web.config中配置的SQL Server名称/IP.您可以通过执行"ping< sql name ="或=""ip =">"来执行此操作在Web服务器上的cmd框中(！).
-尝试从Web服务器通过SQL Management Studio访问SQL Server(！)

最好的问候，

Hello,

There are some points you could check:

- Check the SQL Server Name / IP configured in the applications web.config. You can do this by execute "ping <sql name="" or="" ip="">" in a cmd box on the Web Server (!).
- Try to access the SQL Server via SQL Management Studio from the Web Server (!)
