I have a large number of worldwide sites that need to access a service via a URL.
The site URL cannot be altered as it is set centrally.
The service is hosted locally at each site, as connectivity can be flaky, and therefore the URL has to route to this local server when accessed from a machine within the site.
Unfortunately all the sites and the central infrastructure are within one single Domain Forest and DNS Domain.
Any suggestions Im unable to use a proxy and concerned about the manageability of lots of site specific DNS zones?
