title: Error: Login failed. The login is from an untrusted domain and cannot be usedwith Windows authentication
body: <p>I am working over LAN using sql server inside visual studio 2013. My server has an ip address of 192.168.0.19 and my client is 192.168.0.18 my port is 49170 which i configured at windows firewall. I connect the client into the ip address of the server but i always end up on getting the Error: Login failed. The login is from an untrusted domain and cannot be usedwith Windows authentication. I use windows authentication because i haven't set a username and a password through my installation. I think im getting the error because i must use the Sql Server Authentication. But how? I dont know what to enter on username and password. Please help. Thanks!</p>
