Hi All,

===================================

Cannot connect to Machine Name.

Unknown error. (pfutil90) or Initializarion string was not correct.

Program Location:

I am able to connect through the application that i am developing and through SQL Server Management Studio. I also tried reinstalling SQL Server 2005, No use.
