Problem connecting from PHP

[thiago777]

Strangely enough, I can connect from a another computer in the network but not from the MSSQL server itself.

Like this it works:

PC1 apache/php (eg.192.168.100.3) to:

PC2 MSSQLSERVER(eg.192.168.100.240)

with this configuration:

$server = "192.168.100.240,3730";
$user = "sa";
$passwd = "mypass";
$conn = mssql_connect($server, $user, $passwd);

But like this not:

PC2 apache/php (192.168.100.240)
PC2 MSSQLServer(192.168.100.240 -> the same pc)

with this configuration:

$server = "127.0.0.1,3730";
$user = "sa";
$passwd = "mypass";
$conn = mssql_connect($server, $user, $passwd);

Any clues?
