Hi there, I have followed your guide on Setup RPC over HTTPS with Exchange 2003 (where Exchange is not installed on a Global Catalog server) and it just wont work at all and im now stumped but i need to confirm a few things in this document in the "Modify IIS virtual directories" you dont mention which server this is to be edited i.e. i can only edit my DC because RPC is in the IIS there but there is no RPC folder on the exchange IIS ? and second you also mention "Repeat these steps for the RPCWithCert directory" I dont have this folder in any IIS ? so is this going to stop me from working /conecting ?
My Setup is:
2k3 Exchange Serv on 2k3 OS
2k3 DC server on 2k3 os and is the GC
we have OWA working aswell using HTTPS and no problems ?

please help as i am now at the end of my patience with this

many thanks in advance
Mark
