Hello, I am in the process of migrating from Exchange 2000 to Exchange 2003 with SP2 on Windows 2003 SP1 using a front-end and back-end architecture. A single BE server and single FE server. I am looking for a whilepaper that would details how to setup a front-end server with the following roles and features: OMA ActiveSync OWA - I want to be able to redirect so the users won't have to type /exchange SMTP Bridgehead RPC Over HTTP I am aware of the following whitepapers: http://www.microsoft.com/technet/prodtechnol/exchange/2003/library/febetop.mspx Exchange Server 2003 and Exchange 2000 Server Front-End and Back-End Topology http://www.microsoft.com/technet/prodtechnol/exchange/2003/library/ex2k3rpc.mspx Exchange Server 2003 RPC over HTTP Deployment Scenarios It seems every time I set one thing it breaks the other. Setting a security on one doesn't work for the other. Any ideas beside calling product support? Thanks, TS
