程序写在本机上，数据库在公司里的另外一台电脑上（sqlserver2008），本机上不装任何数据库软件的话，程序能不能连接上数据库

假如我conn.php中输入这样一行代码并运行
存放数据库的电脑ip:192.168.1.221
$conn = sqlsrv_connect("192.168.1.221",array("Database"=>"databasename","UID"=>'sa',"PWD"=>'pass123'))or die(print_r(sqlsrv_errors()));
然后在地址栏输入localhost/cnn.php请问能连接得上吗

SQLSTATE 08001
这是 SQLServer 没有开启远程连接

SQLSTATE 08001
这是 SQLServer 没有开启远程连接

就是说连接远程（192.168.1.221）的数据库是通过我这边的服务器上的数据库连接上的，如果我的服务器上没有安装sqlserver就不能连接到远程的数据库对吗

不是！
SQLServer 默认只提供本地服务（所有的数据库都是这样），如果要他提供远程服务，就必须开启远程连接服务
