We have a remote office which only has 1 Exchange mailbox server.  In all of our other offices, we have at least 2 - a back-end server (mailbox) and front-end server (for OWA/bridgehead).

In this particular office, if I was to install the EV OWA Extensions, which installation should I be using - f/e or b/e or both?
In ESM, it is NOT enabled ('This is a front-end server' is NOT ticked)

Thanks in advance.

Forgot to add, incase it matters, we are running Exchange 2003 SP2 & EV 2007 SP3 on Windows 2003 Enterprise SP2
