Hello Chris,

generally you can restrict pages/sites to be called only from specific IP
addresses. Go to IIS Manager, page, properties, directory security, IP Restrictions.

Keep in Mind - IP addresses can be spoofed and this is no bullet proof mechanism.
But surely a start.

what happens when u would like to add a new asp.net server???
U can ;
1. use client certificates which is my advice..
2. Set authentacation to windows use IIS to configure users which u want to
access. In this case, u should allow only remote machine's IIS user
account...
3. You can host your web services on a different port (like 22849) and then
allow accesses to this port from a specific IP. this is what u say..

Is there an easy way to restrict a web service so it can only called from
asp.net pages on another machine on the network? Ideally I'd like to base it
on IP address.
