Hi, Clem In the Apache link that I provided, it stated that below Apache v2.0.58 supports RPC over HTTP. Any version of Apache above that version does not support RPC. Two reasons: 1. it is not a standard. 2. patents by Microsoft if Apache uses it.

What do you mean when you say that the latest Apache does not support MS RPC OVER HTTP, whereas your version supports it ?? That's not make sense ? If I can do Client -> Apache reverse proxy -> IIS RPC -> exchange 2007, I'll install it as soon as possible !
