Re: Server Network Interface Randomly "Locks Up" What model NIC(s) are in the server? Likewise what is your network configuration? Are you on a real network with managed switches and routers, or is this a consumer-level broadband setup? The former would give you detailed information about packet activity and interface status.
Since you're saying the whole machine is locking up, requiring a hard power cycle, then I don't think it's the network interface that is locking up - sounds like the whole machine is. Unfortunately none of those Event Log screens you posted show anything relevant since you're not highlighting any of importance.
