Hey friends,
In my SQL server 2008 R2, I have found in error log contineously following error:
Login failed for user 'domain\tomt'. Reason: Attempting to use an NT account name with SQL Server Authentication. [CLIENT: 192.9.200.18]
When I have try to find out the details using trace (sys.trace_events) then I got application name only as ".Net SqlClient Data Provider".
I want to solve this issue. Please help me how to solve this Or wher can i get exact information that this request comes from?
