Maybe installation is not the default instance, connection

CodePudding user response:

You said local test or report the same error, then try SSMS can connect, otherwise is likely as # 1 said,

CodePudding user response:

I also met, before you try the server 360 is stopped, or try this function cannot ping the server IP

CodePudding user response:

Thank you for the great god, now good, reason: because the machine is to reinstall the system, because the company need to change IP address to a new IP, before the default database name and IP address, database password revision, then change the database connection string, it is good, thank you, thank you very much!!!!!!
