I have such a problem in SQL? Why?

redice

User 'admin' failed to log in. Reason: Not associated with a trusted SQL Server connection.

You first try to ping pass
Look at what login mode.
Probably mixed mode problem.

redice

It is not a hybrid login, it is windows authentication.

Change to SQL mode login, WINDOWS verification, but there must be some internal matching problems, but we never use it ~

Try with administrator sa and sa

人畜无害

The user name and password for windows login authentication are the user name and password of your local user, and the user's operation authority to sqlserver should be maintained

No connection to the corresponding SQL server.
