SQL Server does not exist or access the problem of rejected

When debugging the program, it is found that the SQL client will not connect to the server.

Finally, I returned the database and recovered.

Check the information, the reason may be as follows:

1, SQL Server name or IP address spelling incorrectly; 2. The server-side network configuration is incorrect; 3. Client network configuration is incorrect.

See if IP, DNS has problems, see if Server and Client are consistent
