I have a problem with an small business server 2008... First off we are using mcafee saas email protection... the issue was that mails inbound were spooled to the McAfee server as the server kept going offline. The owner of the business started adding updates to the server and rebooted it several times.
I got the call last night to look into.
Internal mail is fine so the exchange services are ok, but the external comms are affected. The first thing I noticed was that the available space on all drives has reached critical levels... Of an 80gb os partition, I have 1.5gb available and on 200mb on the data volume. I have freed up an extra 6gb on the data volume, but finding space on the os partition is a little more difficult.
I think the issue is with the os available space... Does smtp services externally stop if the available storage drops below 2gb or something?
