My network cable disconnects at 4pm

[Pyroman]

This is so bizarre, every day for the last couple of weeks at around 4pm my machine pops up the little yellow bubble in the corner to say network cable unplugged, it's only a flash for a second or 2 then it goes back on. Think my machine's trying to tell me to go home =D

I'd take the hint and go

 

If your on a managed switch the logs might help, should show connections and disconnections etc

Check your event logs on your PC, it could be something running as a service potentially.
