I've got this weird problem with the Ethernet controller on my Windows Home Server system. I cannibilized an old Gigabyte mobo with a Pentium-D for WHS, and it has an on-board NVIDIA nForce Ethernet controller on it.
When I'm reading data FROM the server, like copying a file from the server to one of my machines, the connection is beautiful. The number of retransmitted segments is almost nil.
However, when I'm sending data TO the server, like copying a file to a shared folder on it, the segments retransmitted is absolutely awful - like a 60% to 75% retransmit rate.
It doesn't matter which computer on the network is sending or receiving - the result is the same. I've got 2 XP machines and 2 Win 7 machines, and all have identical results.
It's all going through a 3Com Office Connect Gigabit 8 unmanaged switch.
I've tried changing cables and switch ports. All of the cables in the house are Cat 6.
I've fiddled with the settings for the WHS' ethernet controller and nothing seems to make a difference (however, when I turn flow control off nothing works at all).
I can't seem to locate a manual for this controller, so I'm kind of in the dark here.
Here are my settings for the NVIDIA nForce Networking Controller in my WHS. Can anyone see a problem?
ASF Event0 - Boot Failure: Enable
ASF Event1 - Fan Problem: Enable
ASF Event10 - Case intrusion: Enable
ASF Event4 - Heartbeat: Enable
ASF Event6 - Power button pressed: Enable
ASF Event7 - System Hot: Enable
ASF Event8 - CPU Overheated
ASF Heartbeat interval (seconds): 600
ASF Managing Station IP address: Not Present
ASF PET Packet Send Count: 1
ASF Support: Disable
Checksum Offload: Enable
Flow Control: Enable
IEEE802.1P Support: Disable
Jumbo Frame Payload Size: 4500 (was 1500, changed to 4500, no effect)
Low Power State Link Speed: Enable
Network Address: Not Present
Optimize for: Throughput (was CPU, changed to Througput, no effect)
Segmentation Offload: Enable
Speed/duplex settings: Full autonegotiation
VLAD Id: 1
VLAN Support: Disable
WakeOnLAN From PowerOff: Disable
What are those ASF settings, anyway?
Many thanks to anyone who can help me solve this problem.
