Ok, my connection string isn't that complicated, try something more simple like:

ODBC Driver:

Standard Security
 "Driver={SQL Native Client};Server=Aron1;Database=pubs;UID=sa;PWD=asdasd;" 

Trusted Connection
Driver={SQL Native Client};Server=Aron1;Database=pubs;Trusted_Connection=yes;"

OleDB Provider

Standard security:
"Provider=SQLNCLI;Server=Aron1;Database=pubs;UID=sa;PWD=asdasd;" 

Trusted connection:
"Provider=SQLNCLI;Server=Aron1;Database=pubs;Trusted_Connection=yes;" 

I took these samples from http://www.connectionstrings.com. I alway use the oledb provider to connect to SQL Server Express and it works with the sample provided here.

HTH,
