You should be able to connect with the ip address of the server\pc where the sql server is installed. Just use it in the connection string. A couple of possible issues. You might need to enclose it in square brackets []. also, is it the default instance, or is it a named instance of sql server. if it is a named instance, you will need to include that, like servername\instancename. also, if the default port number is not used, you may need to include that. do a google search for connection strings, and you will find plenty of examples.
