SNMP Mibs i PHP

Jeg roder lidt med SNMP i PHP.

Når jeg køre

<?php
phpinfo();
?>

får jeg følgende fejl:
Cannot find module (IP-MIB): At line 0 in (none) Cannot find module (IF-MIB): At line 0 in (none) Cannot find module (TCP-MIB): At line 0 in (none) Cannot find module (UDP-MIB): At line 0 in (none) Cannot find module (SNMPv2-MIB): At line 0 in (none) Cannot find module (SNMPv2-SMI): At line 0 in (none) Cannot find module (UCD-SNMP-MIB): At line 0 in (none) Cannot find module (UCD-DEMO-MIB): At line 0 in (none) Cannot find module (SNMP-TARGET-MIB): At line 0 in (none) Cannot find module (SNMP-VIEW-BASED-ACM-MIB): At line 0 in (none) Cannot find module (SNMP-COMMUNITY-MIB): At line 0 in (none) Cannot find module (UCD-DLMOD-MIB): At line 0 in (none) Cannot find module (SNMP-FRAMEWORK-MIB): At line 0 in (none) Cannot find module (SNMP-MPD-MIB): At line 0 in (none) Cannot find module (SNMP-USER-BASED-SM-MIB): At line 0 in (none) Cannot find module (SNMP-NOTIFICATION-MIB): At line 0 in (none) Cannot find module (SNMPv2-TM): At line 0 in (none)

Mit mibs bibliotek ligger her: C:\php\extras\mibs
Jeg tror det ligger forkert placeret!!
Er der nogen der kan hjælpe??
Jeg køre PHP på IIS.
