Prior to R2, I had OCS 2007 CWA working for both external/internal users, by using a single dedicated server located out in the DMZ. This seemed to work fine. Now, I've upgraded all OCS components to R2, with the exception of CWA. I've read over the docs, and have a couple questions. What's the best method to deploy R2 CWA? Do I really need to have 2 dedicated CWA servers, one for external users, another for internal? Can I consolidate external/internal access to one server, using ISA as part of the solution?
And unfortunately you can't cheat and virtualize the servers and be supported, not on the official supported list due to the desktop sharing component.
