Thanks Chris - I'll give this a try when I get a chance.
One other thing - we've purchased the SBS version of System Recovery which comes with the GRO. However, to get this to work, it says you have to install Outlook, which isn't advisable on an SBS server. Are you aware of the licensing situation that would cover this, i.e. would I have to install the GRO on a desktop machine, but also purchase a Desktop licence for the System Recovery software?
