Event InformationHere is some general guide from newsgroup post:
1 - dont install RRAS in NAT router mode with ISA. That, and installing ICS with ISA is what gets you the ipnathlp

2 - dont use the "Configure your server" route to install RRAS on an ISA server. ISA has to manage RRAS installation
and basic setup through its own wizards.
3 - spoof attacks are usually a result of an ISA misconfiguration (external IP in the LAT, more than one external NIC,
etc.).
