Where can I find out more information on RPC over HTTPS?


Thank you,

Hi Brett, 

I am not sure if this plays a role or not. But most ISP's block port 135
on all traffic because of the known virus attacks going around. You may
want to see if your ISP or the ISP of the person trying to connect
remote is blocking port 135. I do suggest that you look into doing RPC
over HTTPS or OWA SSL and stay away from using port 135 if at all
possible.

Regards,
Andrew

Outlook can not synchronize for remote users, it seems as though the
connection is timing out but can not find anything of that nature.  I
have
looked at the firewall to ensure that ports 110, 25, 135, and those
above
5000 are open and or listening.  We have been experiencing a lag in
connectivity here in the office as well, that is also unexplainable.  If
anyone has any ideas because I am running out of where to look....
