SMTP is the core engine for Exchange 2000. SMTP has to be running in the Exchange 2000 server.

It works OK for a couple of days then stops. Is it not a best practice to disable that service and just open up port 25 for exchange? I guess I will need to buy a SBS server book. I have another SBS environment where my isa publishes to an internal SBS exch server and on that isa firewall I do not run the SMTP service. Any suggestions for the stand-alone config with SBS, do I need to keep the smtp service disabled and do something else? Thanks, Peter ------------------------------------------------------ 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 ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: raj.periyasamy@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
