Is it possible for a hub transport role to be in more than one site? Lets say I have two AD sites, but only want one hub transport, can I get that hub transport to be in both sites?

No, the site is determined by the OS and a computer can only be a member of a single site. This is not Exchange specific.You can find out what site your computer is in by typing nltest /dsgetsite a the command prompt.Mike Crowley: MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator

I should also mention that you don't need to put a HT in every site. Just the sites with mailbox servers. And if they are small sites and you're not clustering, you could combine the mailbox and HT role... Mike Crowley: MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator

Hi,Deploying more than one Hub Transport server per site provides redundancy if a server fails that is supported, but cannot install one Hub Transport in more than one AD sites .As Mike said, the server indeed doesn't do this.ThanksAllen
