Look in your ISA FWEXT..logs. If your publishing rule is working, you'll see entries using TCP-135, with "Accept" and an sc-result code of 0, 20000 and 20001. Any other code spells trouble. Also, check your IPEXT..logs; if TCP-135 shows "blocked", then your rule is incorrect.

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 ?
