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,

Sabine
