It was late here and I'm having problem thinking of a solution for this. There's this Windows Server 2012 R2 in our environment, and it has 3 NIC on it.
I have observed that this NIC-1 is giving a trouble, it will lose connectivity to the gateway in every 30 minutes interval.
NIC-1 IP: 10.1.0.101 Default Gateway: 10.1.0.1 Mask: 255.255.255.0
At least, there is another 2-3 servers (same OS) behave like this now. They will periodically 'Request time out' on NIC-1 interface, but not on the other 2 interfaces.
Where should I begin to look for faults and fix it?
Thank you in advanced!
