Hello, Recently, I've tried to publish my Exchange server through RPC. I think I did my homework well, reading documentation attached with ISA Feature Pack and available on isaserver.org. I've implemented a "split dns" for my external domain. My private internal domain cannot be resolved from internet. Unfortunately publishing does not work. When I've setup new mail account in Outlook on client computer connected to internet everything seems to be ok (server name and mailbox was checked and verified) but when I tried to connect to my published Exchange server I've got an information: 'Exchange server not found'. On internal network, as You can guess, everything works well. Could You give me directions what I can check ? Regards, Tomasz Skorupa
