Hmm, that's strange. I setup RPC over HTTP just a week ago using domain.local internally and domain.com externally. And it works fine for me. But, I only have one server, so no front-end/back-end scenario here... I followed this document: http://support.microsoft.com/?id=833401 I think this document is very helpful, especially on how to setup SSL. In the beginning, I created my own SSL certificate, which makes it a bit more difficult. If you buy a certificate, it's easier since the certificate will be automatically At the validports registry entry, I added the following: <netbios servername>:6001;<servername.domain.local>:6001; <netbios servername>::6004; <servername.domain.local>:6004 Good luck, Dennis Appelboom XB _____ From: Ara [mailto:ara@xxxxxxxxxxxxx] Sent: maandag 4 april 2005 4:39 To: [ExchangeList] Subject: [exchangelist] RE: RPC over HTTP: - Problems accessing from outside our network. http://www.MSExchange.org/ There has been a discussion going on isa server list regarding this issue and looks like the only option is to either use a split dns or let them vpn.
