Logon Login failed for user . Reason: Attempting to use an NT account name with SQL Server Authentication.
I have a Windows domain account like gooled\solarexpert that is set as sysadmin on mssql database, connect to Solarwind application. The application connection is not successful. I check the database log, it is "....Reason: Attempting to use an NT account name with SQL Server Authentication."
I use this account gooled\solarexpert on other database with same setting, it's no issue to connect. Most are nnncet5ed successfully, only few of them is with this error message.
I have tried almost all suggestions posted from web about this error, it still doesn't work.
My server is mssql 2012
