Exchange server 2010 unavailable until network connection is repaired
Posted on 2012-09-11
we have recently installed an Exchange 2010 server on a 2008 R2 server at a customers site. Since installation, some users (mostly XP and Office 2K3 & 2k7) have issues first thing in the morning where Outlook reports that the server is unavailable. If you repair the network connection Outlook then re-connects and works perfectly for the rest of the day. The same server is also being used for DNS and DHCP although there is nothing in the event log to suggest that these services are having issues. There's also nothing in the event log around 9:00am that would suggest why Exchange all of a sudden starts to work and allow Outlook connections without the need for a network repair around this time. I've checked the scheduled tasks and again there is nothing for around this time.
