When I try to RDP to a computer with 2 screens, from a computer with 2 screens, I can only see one of the screens and not the other.

Does anyone know how to resolve this?

I'm using multimon as a switch on mstsc but this doesn't work, as I can't see both screens.

I can't use span as I need to see both desktops of the remote desktop.

AFAIK the multimon switch is only functional on RDP 7.0 on Win 7 or better

In XP you have the option of "Span"

Otherwise you'll need a third party tool

Yes it's strange that on all other products (VNC, Teamviewer etc etc) you can see both monitors, just not on remote Desktop which is the product I need to use.

I've installed this update and it reports that the Remote Desktop Connection versions are as follows -

 - Shell Version 6.1.7600
 - Control Version 6.1.7600

Is this right for having version 7 installed?

Use the mstsc /span command and it will allow you to view the multiple monitors:

Using the /span switch only allows you to view one monitor.

I need to use the /multimon switch so that I can view both monitors of the remote PC.

6.1.7600 RDC client will work but you also need a Win7 (or Server 2k8 R2) machine to connect from.  If you have a win7 machine available you can see yourself.  The RDP client needs the OS to match - otherwise spanning or third party solutions are your only options.  Microsoft were pretty late to the party with multimonitor support for remote desktops.
