To use the full exchange server client, you must open up the RPC endpoint mapper port (135). You can set which port exchange actually ends up using, but 135 is used to initiate the process whereby the client learns that port number. -----Original Message----- From: Michael Boggan [mailto:MBoggan@xxxxxxxxxxx] Sent: Wednesday, August 27, 2003 10:41 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] OT: Exchange thru internet 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.
