[PHP] Using @file

[Jeff Lewis]

I am using this line in part of my code but am getting an error that looks like below:

Code:
$serverDetails = @file("http://www.myserver,com/versions.php?l=$scripturl&v=$version";);

Error:
2: php_network_getaddresses: gethostbyname failed 
(c:\inetpub\wwwroot\yabbse\Sources\Admin.php ln 43)

What would be causing this error?  It works on some machines but not others?
