The user is not associated with a trusted SQL Server connection. (.Net SqlClient Data Provider)
June 20, 2008
I was also facing this issue every time I install the sql server. It occurs initially and once we fix this then onwards it disappears. I have followed the instructions explained in the below blog post. It was very useful to me. I hope you will also like it.
