MS SQL conn string

My MS SQL Server was working perfectly fine locally when I used the following connection string:

server=(local)\\DB;Integrated Security=True;uid=;pwd=;database=AspNetDb

When I moved my SQL server to another machine within my LAN, it stopped functioning.
server=(192.168.1.3)\\DB;IntegratedSecurity=True;uid=;pwd=;database=AspNetDb

Could someone kindly give me some advice? I appreciate your assistance.look at:
