    For PIC does the access edge server need to be able to talk to a DNS server or will a host entry for the following be enough

     

    sip.oscar.aol.com

    lcsap.msg.yahoo.com

    federation.messenger.msn.com

     

    The reason for asking is that the access edge server is in a DMZ and the firewall rules block DNS.

     

    Thanks for any help

    Adding the hosts you listed to a hosts file with the correct IPs should allow PIC to work, but you will not be able to federate with any other OCS servers without adding their IP addresses to the host file as well.

    We are in the same situation.  Are the 3 addresses listed at the beginning of this post the only addresses that are required?

    Fairly confident the answer is yes. Look at your access edge under the IM provider tab.
