Hi Matt,
Any joy yet? You mentioned a load balanced url, but only a single wfe, could you clarify what you mean there?
I don't quite understand why you are using port 25000 and then trying to access on normal port 80. If you want to access it on http://moss.company.co.uk then I would be looking to create the web application on port 80 unless I was using ISA or other proxy in there.
Hope that helps.
Iain
