Thank you Enrico. The name is a reference to an Asterix character (I'm a big fan).
OK, that's the simple things out of the way and unfortunately they haven't helped. Some other thoughts:
- What are you using to initiate the (outbound) file copy on the Vista machine? Does it make a difference whether you do it from Windows Explorer (copy, paste) or the CMD prompt (map a drive to the remote machine, then x/copy to the remote box via the new drive letter)?
- What about outbound HTTP and FTP PUTs from the Vista box? Are they also much slower than expected? For example, if you were to set up a HTTP or FTP server anywhere else in the house, is uploading from the Vista machine also slow? (You could use an internet server for this test, but the limiting factor might be your link speed.) I'm trying to gauge whether the outbound speed problem is limited to one protocol (SMB), or whether it affects everything.
- Do you know how to generate a packet sniffer trace? It's not hard. Go to
www.wireshark.org, download, install, start a capture on Vista's LAN interface, repro the problem by copying a file, stop the wireshark capture. If the points above don't lead anywhere, I'd be curious to see a packet trace.
