Peculiar networking issue

Question

Hi

Two dell servers; Windows Server 2016 Standard DC (PE T440) and Windows Server 2012 R2 Standard member server.

We have a peculiar networking issue. We started getting network connection issues. This happens for a few seconds and at no particular interval but let’s say once every one to two hours.

Here is what we noticed;

On member server the RWW connection will break for a few seconds and then restored.

However we also get MS Access database crashes which complains that network connection was lost and to restart db to continue. The MS Access database was running from a shared folder on the DC. We moved the db to a shared folder on the member server but MS Access database still crashed.

We moved both DC and member servers to a different switch. No luck. We reinstalled Windows Server 2016 standard on DC and moved back MS Access database to a shared folder on DC but still no luck and MS Access database still crashes.

Could all this be due to DC hardware networking issues such as faulty network card or network cabling connecting DC to switch? At this point I am considering changing both DC’s network card and cable.

Is there something someone can suggest to home in on this issue?

Thanks

Regards

Hi, that's really some peculiar issue I guess. The fact that the problem is happening from time to time and not in a certain pattern made me think that the problem was not caused by the server. Here I will suggest you to update NIC drivers and firmware. https://dell.to/3pQOyst If there is no error in the SEL log then I would think that it is more likely to be caused by DC networking. For example, I think it might even be the cables.

Please update here on how it goes!
