I have SQL Server 2005 and Windows Server 2003. Recently I formatted and reinstalled all programs of an user computer of the WorkGroup that could access the sql server but now when I try to access to the SQL Server from the formatted computer with the same user and password I get:Login failed for user ''. Not associated with a trusted SQL Server connection.
I have the Windows Authentication in the SQL Server enabled.
Can anybody help me ?
Thanks in advance.
