HI

Thanks to all my friends that help me for solving my problem. I finally solved my problem .After adding the Users in sql(my DB) and using firwall.cpl for its exceptions (as my friend Karthik told mein this Page

)
,I used this Connection and it works.
I will copy my connection here maybe another person use it .
"Data Source=MyserverName;Initial Catalog=MyDataBase;Persist Security
Info=True;User ID=sa;password=password of Sa";
Thanks :-O
