G'day mate

Is it exactly every 5 minutes? If its quite frequently rahter than every 5 mins exactly I'd try patching it into an alternate network port to see if the port is failing. Also swap the Cat5 (long shot)

Is this box exposed to the internet?  Are you running services available from external?  Could someone be runnihg a DOS on your box?  IS it patched with current AV installed?

Are you plugged into a Cisco switch?  I've seen a simular issue for client on Cisco switches where portfast wasn't enabled on the access ports.

Might also turn off the power saving Auto configuration on the Power Mgmt tab of the NIC...  (Device Manager)

Test by issuing a constant PING against an inside resource...

ping -t IPAddress
Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

Thanks Fatal_Exception

Can you explain me how would turning off the power saving auto config relate to my issue. I think this is the setting that fixed my problem.

Power Mgmt is one of the nicer additions to the newer systems, but as usual, does not work 100% of the time...  You could reload the OS, and thusly a new ACPI, but...  glad that it corrected the issue though...
