SQL Error Log: Login Failed for User ''

[#1]

Hi B1 experts,

currently i have a little problem with our SAP System or better SQL Server. Everytime when a SAP client is started, the SQL Server get the following warning message:

Login failed for user ''. Fehler bei der Anmeldung mit der SQL Authentifizierung. Der Server ist nur für die Windows-Authentifizierung konfiguriert.

Fehler 18456, Schweregrad 14, Status 58.

The same message occurs when i log into sap. The funktionality of SAP is not impaired.

I have checked the server authentification mode and the sql server is SQL and Windows Authentification configured.

SQL Server: 2008 R2

SAP System: SAP B1 8.8 PL19

Client System: Windows 7

Someone any ideas?

Regards,

Hi.......

Please be sure that your SQL services are ON.

Go to Configuaration tools and configuration manager and ON all the piped network connections and also restart SQL services here.....

Put all the services on Automatic mode.....
