Pre-defined vars not working

The thing is that I reinstalled win2k, so I did with apache, mysql, php 4.1.1 the same. I installed php (U know, editing php.ini-recommended, copying files everywere, etc), and tested it with some old scripts I have. Well, the problem is when I tried to exec my home page. It has a basic IP recognition check, for me (loopback and 192.168.1.1) and some friends, that always worked. this time not, it showed me the message for unknown users that I have predefined if the user IP is not on the database. Then I wrote a small script, this one: <? echo "<br>Nombre del servidor: <b> $SERVER_NAME </b>"; echo "<br>Versión de CGI: <b> $GATEWAY_INTERFACE </b>"; echo "<br>Software del server: <b> $SERVER_SOFTWARE </b>"; echo "<br>URL referida: <b> $HTTP_REFERER </b>"; echo "<br>IP del cliente: <b> $REMOTE_ADDR </b>"; ?> with lots of predefined vars. none of them showed. Some other basic scripts I wrote worked like a charm. So I began the uninstallation. First I deleted php.ini from c:\winnt and c:\php and... well, the not working scripts became alive and began to work. So it´s a misconfiguration of php.ini, and without it it is using default settings. What should I look for? PHP 4.1.1, Apache 2.0.28 (correctly configured), win2ksp2, blah, blah, blah Thanx in advance...
