Today I changed 'sa' password to my SQL Server.
It works fine, but I cannot acces the DB from any of the applications. When I try to login from the application window, it says: ,,Login failed for user sa,,.
I don't know how to solve this problem. I think I'll have to replace the old password with a new one also in some kind of connection code-lines, but I don't know how or from where. I don't know the older password.
I'm sorry for my bad English. For any questions, please aks.
I hope you can help me,
