I was trying to figure out why I couldn't configure RPC over HTTP for Outlook 2003, I had XPSP2 installed, I was running Office SP1, It's all supposed to be functional.
Apparently, because of my wacky installation point, I had a registry key set which prevented the UI from showing up. Frustrated about this, I got to thinking. Some people out there like to disable things they don't want their users to play with, so I thought I'd post it here.
In the registry key HKCU\Software\Microsoft\Office\11.0\Outlook\RPC there is a DWORD EnableRPCTunnelingUI. If this DWORD is set to "1", the UI shows up regardless of how the server is configured. If the DWORD is set to "2", the UI will not show up.
Seems simple now. I guess that's why they say hindsight vision is 20/20.
