Çözüm

SQL Servisinin kontrolü,

Services.msc ‘de SQL Server (InstanceName) servisini kontrol edin. Stop durumunda olan servisi Start ederek çalıştırın.

Veya SQL Server’a göre ilgili komutları komut satırında çalıştırın.

net start MSSQL$SQLEXPRESS2012
net start MSSQL$SQLEXPRESS2008

MaestroPanel Agent SQL Connection String kontrolü,

%MaestroPanelPath%\MaestroPanel\Agent\Config

adresinden sql2012.config dosyası içerisinde connection stringleri kontrol edin.

Bilgileri hatırlamıyor ve yanlış bilgiler yer alıyorsa SQL Management Studio ‘a Windows Authentication olarak oturum açmanız ve Security > Users SA kullanıcısının şifresini değiştirmeniz yeterlidir.
