It says it's unable to bind a socket for the published Exchange server due to error 0x80070034 and it reports it's being attacked from everywhere (including internal servers), which is most likely not true. It is accepting e-mails from certaind domains but not from most others. Anyone know hot to start from scratch? I've restored an older configuration, dating back when the server was working OK but I still get the publishing error. Should I just uninstall ISA and install it back? It's a complete mess. One thing I should probably mention: I'm trying to use the same internal and external DNS name for the mail server, so that my mobile users can use the same name when looking for the mail server from within or from outrside. Because I've noticed that the ISA was trying to find the server on his external interface (published at NetSol) I've added a hosts entry hard-coding the name to the actual internal IP of that mail server. Any ideas, anyone. Thanks a bunch, Steven
