Network Interruptions

[kwasek]

Hi all,
I have a strange problem for last 3 days. My network is interrupting .
My network is stopping on both cards in few seconds intervals.
I don't have any idea what it can be.
I have attached network performance charts ( two NIC's )
Any help?

Check event viewer for errors or warning. Try also to restart your switch and change port.
