The Open Systems Interconnection (OSI) stack encountered an unexpected condition during normal message flow. The affected connection will be restarted. This event can occur when there are networking issues in the environment. You could also see related message transfer agent (MTA) events indicating network connectivity problems.
If message flow is not affected, ignore the condition. If message flow stops, restart the MTA service. Check the network interface card (NIC) on the server to ensure that it is functioning properly. Ensure that the latest NIC drivers are installed. If the condition persists, contact Microsoft Product Support Services.
