SBS2011 server w/ AD, Exchange 2010, DNS Server. All clients use Outlook Anywhere. HP Proliant ML350-G6/16MB.

About a week apart the system required restart twice with the same issue...The majority complaint is Exchange is not processing mail. Can still login to system, TCP working (ping router, remote desktop okay etc) IE gets 404 errors. Exchange Management Console cannot initialize and connect to Exchange.

Looking at error events, DNS server appears to be a common suspect. Around the same time as the problem, DNS Logs event ID 404 followed by ID 408 and these two events repeat about 8 times (in same second) before system resources stop.

DNS Event ID 404 described below: (I can't find a description of ID 408)
The DNS server could not bind a Transmission Control Protocol (TCP) socket to address The event data is the error code. An IP address of can indicate a valid "any address" configuration in which all configured IP addresses on the computer are available for use. Free memory or other system resources
Restart the DNS server or reboot the computer."

This system has been running fine for over 2 years. Required a restart 12/31/2013 and again on 1/7/2014. I haven't had a chance to look into this, but Windows Update was run on 12/23/2013, about a week before the first symptom appeared in which about 40 updates (important) completed successfully.

Thanks in advance for any help on this....
