You lost me a little on the direct connection. Do you mean to disconnect my PC and the NAS from the router and connect them together with a network cable? If so does that have to be a cross over cable? Currently my network is setup as 192.168.10.xxx
I also just got some clues from Microsoft so I start with some of their ideas. I do have jumbo frames enabled on this 64-bit PC sp I guess I could start by turning that off, it currently is set to "9KB MTU". Some other settings on the NIC that might mean something to you are:
802.1Q/1p VLAN Tagging: Enabled
Flow Control: Enabled
Large Send Offload: Enabled
Speed & Duplex: Auto Negotiation
The NIC is an onboard Realtek 8111D
Here's the MS post:
I know of no reason why it shouldn't work, George. Therefore, I strongly
suspect something amiss in the AV, or in the NAS itself. I do know that XP
x64 is fussier about RPC packets than 32-bit XP. You might try enabling File
and Printer Sharing in Windows Firewall. And verify that Client for
Microsoft Networks is enabled in the TCP stack. Finally, I'd look at the
network card itself. If it has TCP Offload enabled or large packets, or any
other advanced features, I'd kill them.
