We have already exchange 2003 server under cluster environment. We don't have front end exchanger server seperately now requirement is to segregate back and fron end server from the existing environment. main purpose to configure front end exchange server to configure RPC over HTTP proxy i.e. outlook anywhere Now, my questions are 1. What's precaution need to be taken while installing/configuring front end server? 2. Do i need to change any setting in existing Exchang 2003 cluster mode server? 3. Do i need to make changes in our Active Directory services? if anythig else need to be considered then please include those points also. Thanks
