http://www.msexchange.org -------------------------------------------------------First - I apologize for not beeing more spesific ... The Exchange is sitting in our DMZ-domain, Outlook clients in our corporate network wich is behind a firewall (this network is being NAT'ed). Further there is no VPN connection and unfortunately we're still running Outlook XP here so I guess RPC over HTTP is not available to us. Outlook is configured to always prompt for user, password and domain and I've been dooing some regedits setting Rpc_Binding_Order and such - all to no avail. And - there I am - been searching for a working solution for days - and now - stuck! Any pointers is highly appreciated regards, Sture > http://www.msexchange.org > ------------------------------------------------------- > Where are these machines that are not joined to the domain located? > (a) Inside or (b) Outside the firewall? > > If you said (b), do they have VPN connection to your interanet? > (a) Yes (b) No > > If you said (b) they need a VPN connection, or if they are using Outlook > 2003 on Windows XP, you need to configure RPC over HTTP. > > If you said (a) to either question, what procedure have users been given > for > connecting to the domain?
