LAN clients connection broken, ethernet device wonky

[darkultra]

I'm not sure how to explain this but here we go. Every now and then (maybe twice a week) all LAN clients lose connectivity and the usual "limited connectivity" exclamation mark is displayed over the network icon in the notification area. The server can still connect to internet, and everything seems peachy with ipconfig.

If I reboot the Wingate server, everything is fine again. The wonky thing is if I try to disable and re-enable the local network adapter, it won't turn grey. If I try again a few times, it does turn grey, but then won't turn on again. If I now try to reboot the Wingate server it will be stuck at "Restarting ..." and I need to hit the reset button.

Hi

normally the message about "limited connectivity" in this case will occur if the client couldn't renew their DHCP lease. So I would look for issues logged in the DHCP service logs - you are using WinGate for the DHCP server for the LAN?

Disabling / re-enabling the network adapter can have issues on Vista and later if the engine is still running.

Success!

I swapped the server motherboard to a Asus Maximus VII Gene and it has been fine since.
