RPC over HTTP on Front End Exchange Server

Hi.  I've been reading instructions on setting up RPC over HTTP for my outlook 2003 users but I'm a little confused.  I have an existing Front End OWA server, which of course isn't good enough for my remote users...  Can I configure the RPC service here as well and use the existing certificate that I'm using for OWA?   All of the instructions I'm seeing are treating this as a new Front end server rather than working with an existing OWA install...

If you already have a frontend server then the configuration is very simple.

1. Install the RPC Proxy component from Windows Components.
2. On the backend server/s set the GUI in ESM to backend on the RPC-HTTP tab.
3. On the frontend server/s set the GUI in ESM to frontend on the RPC-HTTP tab.

Wait about 20 minutes. Test.

You can test it on Microsoft's test site using a test account here:

There is no need to do anything else.

thanks guys.  I made the change on the backend server to use RPC over HTTP last night before I left thinking it would be no big deal.  I noticed this morning I had no internal email coming to my Blackberry.  Our phones are directed to my OWA server for push mail.  I also could not send a message from the OWA interface.  The body of the message was grayed out with a red X.  I already have the Vista patch for OWA, so this wasn't an issue before I made the backend change last night.  Anyway, I came in and changed the backend back to use RPC over TCP/IP and email flow resumed and Owa is fixed as well.  Any ideas what the issue was there.  Is it simply because I didn't set up RPC_HTTP on the FE server or is there a deeper issue?  thanks in advance...

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The RPC setting should have nothing at all to do with either the operation of OWA or email flow. Nothing whatsoever.

Are you accessing OWA through the frontend or the backend server?

The only thing that could cause the problem would be a misconfiguration of the virtual directories in some way. Resetting the virtual directories on all Exchange servers would rule that out.
