 PC hanging - Kevin
>So that's something internal in the PC? Either software or hardware. Not the NAS. Is that what you're thinking?

No. A warm reboot should be exactly the same as a cold boot except it misses out the POST. All hardware and connections are reset and reinitialised just the same. For me, if the problem is still there after a reboot it points the finger at the NAS.

I don't know the SMB protocol and how it works from a logical viewpoint but is the server (NAS) stateless or does it keep a table of what it thinks is the current state of each client connection? I've seen problems where stateful servers have got out of sync with a client and will ignore any message from that particular client unless it is the exact one it is expecting, even a "OK, let's start again" message. It needs something to force it to clear down the connection status and wait for a reconnect from the client.

Can you unmap the client from the NAS at the NAS end? If you can, have you tried disabling and re-enabling the individual client on the NAS when the hang occurs?

If that works and I'd got time on my hands I'd be reading up on the SMB protocol and firing up wireshark to see if I could see any sequence of messages that seems odd. (Wireshark can be filtered on the port number and can decode SMB packets into readable message types)
