I've inherited a network w/ no documentation and a taxed server. The server ran out of memory causing all of the services to go down. With a restart, all services, including email would resume. Before the additional RAM could be delivered the restarts failed to resume the email services as it once did. After installing the Additional RAM and creating room on the C drive I began to troubleshoot the email issue. Internal mail is being routed, but receiving mail from outside of the domain is an issue. Currently running exchange server 5.5. Everything worked before the server started to crash. The event log records MSExchangeSA event id's 3101 and 3100 continuously. Can anyone guide me in the right direction?

Can you post the exact and complete errors? All the Exchange services running? Sounds like something with the IMS, but hard to say. 5.5 has been out of support for so many years.

I don't think many people remember event-ids, especially those from 12 year old software. :-) How about posting the rest of the information. Is it safe to assume that you've verified that it's SMTP that's the problem? A simple "telnet <server-ip-address> 25" should return the server's 220 SMTP banner. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
