I have to ask, just because I had this problem initially as well. Do you have unique names for each connection. I know I had to give each connection a different network connection name on each side. Say I had three offices in different states that need to be connected (GA, NC, and SC). I would make 2 connections and users on the local machine for each site to site VPN and name them as source_destination. GA_SC, GA_NC, SC_GA, SC_NC, NC_GA, and NC_SC. The First part of the name would be the connection, with a user on the second side being created with the same name. So the GA Server would connect to NC with the GA_NC username that was created on the ISA Server in NC. Likewise, the NC server would also be able to connect to the GA Server with the username NC_GA that was created on the GA Server. Same would go for each server pair. I set them up both ways so that either server can initiate the connection when needed. Also, you mentioned that the VPN was connected through RAS. In the RRAS Snapin, does the connection show up as a Dial-In Client, or a Network connection? If it is a Dial-In client, then there is something wrong with the configuration. -- Taps@xxxxxxxxxxxx http://Taps.Iniquity.Org - "What spirit is so empty and blind, that it cannot recognize the fact that the foot is more noble than the shoe, and skin more beautiful than the garment with which it is clothed?" -- Michaelangelo Build a man a fire, and he'll be warm for a day.
