Yes, you're right that was it, later it ran, yesterday in the morning also after 2 hours it came back. Then it ran also today in the morning and since 30 minutes the problem is another time back. And I get the message from the EventLog "Login failed for user 'sa'. [CLIENT: <local machine>]".

I am unsing SQL Server 2005 Express Edition and splendidCRM uses it own instance (default installation).

You have any idea because I get this problem every day? In the following the System Log of Splendid CRM.

Thanks for helping
