Anyway, I don't know what CLI is....? I see the error on the web. As for a DSN, I didn't think I need one connecting this way. That is why the uname, password, database is supplied, no? This should be a "dsn-less" connection.... Either way - I tried adding a DNS on the web server, that points to the SQL database, and that connection works...but the code I'm using from the web page still does not.... If I use the code you gave me, this is what I get: Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: INTRA_SQL,1433 in D:\Inetpub\wwwroot\cratos\test.php on line 2 Fatal error: Call to undefined function mssql_error() in D:\Inetpub\wwwroot\cratos\test.php on line 2 Please advise... Try something like this: $dbhost=\\\\SERVER\\INSTANCE_NAME,PORT; $dbuser="USERNAME"; $dbpass="PASSWORD"; $db_connect=mssql_connect($dbhost,$dbuser,$dbpass) or die ('Server connection failed'); $mssql_database = mssql_select_db("DATABASE", $db_connect) or die ('DB selection failed'); Same thing: Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: \\10.10.103.222\INTRA_SQL,1433 in D:\Inetpub\wwwroot\cratos\test.php on line 5 Server connection failed
