i build application for my work, and the only problem that im having is that i cant connecto to the server on my desktop computer. i put this connection string in my app and from my pc to my pc i connect.

"Data Source=sony-02391;Initial Catalog=QADB.MDF;Integrated Security=SSPI;"

the issue is when i copy the app to another pc on the network it says that cannot connect. is there any problem if the other pc is outside the workgroup im in.?

thank you in advance for your help guys. im new in programming. thanks again.
