Multi-site Exchange2003 internal/external name resolution

I have a customer with 2 sites, both are in the same domain domain.local with a DC+Exchange 2003 on each site. There are mailboxes on both Exchange servers. The sites are connected by vpn using a 3rd party thing I know little about. They each obviously have their own internet connection and reasonably autonomous. Both sites are set up so that mymail.washingtonoffice.com forwards to the washington office's external IP/exchange and mymail.sheffieldsite.com goes to the  sheffield site's ip/exchange.

Either site will let me open OWA, but when it tries to authenticate and the mailbox whose credential I use is stored on the OTHER server I get forwarded. Which would be fine but it forwards my browser to the INTERNAL fqdn of the other server. Internally they are using a .local domain so obviously I cant set up DNS for them!

Is this meant to happen? Is there a way round it? I found the following technet article and the submitter is having precisely the same problem as me but nobody has replied yet. I thought I would ask the real experts :o)

Yeah I was afraid you were going to say that. I'm going to have to make them spend more money I guess!
When a client introduces a second Exchange server I tell them that they need to budget for a third server to act as a frontend. Trying to run a multi server environment without one is challenging.

If your question has been answered, pleased remember to accept the answer and close the question.
Suppose I do the following:

Create a web page, plain old html that has 2 links, one that says "click here for sheffield users" and another for washington users. Those links then forward to the OWA page for the relevant Exchange server/site.

Obviously that relies on the mailboxes being held on the right servers/sites and the users clicking on the right thing. What do you reckon?
That is one way.
Or the users need to know which server their mailbox is on.
