Its running standard edition and its been setup as a web proxy, email publishing using exchange 5.5 behind the ISA. Everything is working fine on the server, but if I do a port scan on the system it shows SMTP and IMAP4 as open. I have taken a look at the settings on my own offices ISA server and it is setup exactly the same and these two ports are closed. Can anyone point me in the right direction of where to look as I have checked everything out Thanks in advance Paul Crisp Snr Network Support Analyst ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: gabriel@xxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
