[Orestis Apostolopoulos]

Hi... I'm Orestis from Greece...

I working on a helpdesk for my univercity using mysql 4, php 4 and IIS for locally design and testing...
The I send with ftp the file in a linux server....

Locally everything works perfect... (connect, queries)

When I try to run it from the site the execution of php file stop at sql queries...

I try to check the privilege of root in sql server but he has it all...
I can't thing anything else....

PLEASE HELP....

Here is a part of the code:

$link = mysql_connect("localhost","root","") or die("Could not connect");
mysql_select_db("helpdesk2") or die("Could not select database");
$Result = mysql_query("SELECT * FROM Administrator") or die('Could not execute query');<---- STOPS HERE!!!! prints 'Could not execute query'

If i remove the die from query then print:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in

Thanks....
