FrontEnd Active Directory Auth. Question

[KARR]

All,

am using OWA on my FrontEnd Exchange Server to access my email from a BackEnd Exchange Server across an Intranet Firewall.

Is the Front End authenticating to ADS through the BackEnd Server on the internal network? Or should I set up the Intranet Firewall to allow across to my Active Directory Servers via specific ports?

Thanks

Rob

The FE server will communicate to both. The FE server must be authenticated to the domain so a bunch of ports must be open. It will also have to be able to connect to the BE to display the mailbox contents. Check out this KB art:

Thanks for the reply. I printed out the MS articles and will look it over tonite.

What I am trying to find out is on my intranet firewall there are 3 interfaces (External, Trusted, and Optional)

The way I thought is that:

External - Connected to FE Server
Trusted - Connected to BE Server

or should it be

External - Connected to FE Server
Trusted - Connected to Internal Network (GCS, AD Server)
Optional - BE Server

Thanks
