Hello, we have two Dell R720 machines that are developing a network patch cord trend issue. We are running several VM machine on the R720s under Hyper-V. What is starting to happen, is that we loose network connection to the R720 or to specific VM machines. The solution has been to figure out which NIC card the issue is related to and to simply reseat the Cat6 patch cable (unplug and plug back in).
We are unsure if the issue is related to the R720s or our switch stack, but we do not have any other issues with our switchs / other devices, so I would think the issue is with the R720s.
I am planning to use fiber optic cabling for network soon, but would like to know if anyone has heard of this issue before.
Thanks
