How to troubleshoot Event ID 4 from Source q57nd60a. The network link is down. Check to make sure the network cable is properly connected.
HP Proliant Servers with Broadcom NetXtreme Network Card can continuously log Event ID 4 and 11 from Source q57nd60a and you can get disconnected from a remote desktop session with the message, “HP Ethernet 1Gb 2-port 330i Adapter: The network link is down. Check to make sure the network cable is properly connected.”
Problem Description :
In our case we continuously get disconnected from a remote desktop session on a target Windows Server 2012 R2. Once we analyzed the SYSTEM Event Logs we figured out that the Server is continuously logging Event ID 4 and 11 from Source q57nd60a every a few minutes.

Solution :
I was pretty sure that there are no problems with the Network Cables or Switches on this Server and in the past we had several problems with the Scalable Networking Pack on Windows Server 2003 R2 and the Network Card Drivers Advanced Features therefore I decided to disable some of the Advanced Features of the Network Card.
As a first step I disabled the following features and BINGO ! The problem was resolved.
1) Ethernet@WireSpeed
2) Large Send Offload V2 (IPv4)
3) Receive Side Scaling
4) Speed & Duplex
5) TCP/UDP Checksum Offload (IPv4)
