I want to be able to hit my exchange thru the internet but to do it it says that the RPC port 135 has to be opened. Well I don't want to do that for obvious reasons. Is there a way to change which port the RPC uses for exchange? _________________________________ Michael Boggan Network Engineer/Citrix Admin Virtual Desktop Inc.
