which snmp mib to monitor windows page fault

I have to monitor a bunch of linux machines and also a few windows box.   I am running opmanager under linux.  Because of this, I cannot use wmi.  

Which snmp mib should I use to monitor page faults under Windows server 2008?  Note that memory utilization is not useful because with virtual memory, windows server 2008 is always showing full memory utilization.
