Has anyone else experienced a problem transferring large, single files to
Vista RTM over a LAN/WAN using Explorer?

I've discovered I simply cannot transfer a large (3.41GB) DVD ISO image to
my Vista Business workstation from a LAN-connected XP Pro SP2 workstation.
Vista explorer spends all its time trying to calculate the transfer time and
after 12 hours never transfers a single byte of the file. Looking at the XP
machine, no session is even open. Attempting to select the mapped drive in
another explorer session results in an Explorer hang. The original explorer
session cannot be successfully canceled, requiring a Vista reboot to clear.

I'm guessing the workaround is to transfer the file via the command line.

Yes I've seen this with transfers to Windows 2003 servers in the domain
also.

line.

On the machines we depend upon to actually get real work done we found the
best workaround was to re-install XP.

Pulling the file To XP seems to work with lots better speed (Still
not as good as XP to XP) than Pushing the file From Vista. (the
reverse direction is also true)

My problem may be related to a known problem with Vista communicating through
some network devices that don't support TCP/IP window scaling (enabled by
default in Vista). It think it can be disabled via "netsh interface tcp set
global rss=disabled� or even by using the "Diagnose and Repair" option on
your Vista network connection.

Oops... I provided the netsh command to disable receive-side scaling.

Here's the correct command to disable TCP auto-tuning and explanation:

netsh interface tcp set global autotuninglevel=disabled

If the issue no longer occurs, this reveals that you have a network device
in your environment that doesn’t support RFC 1323 “TCP Extensions for High
Performance�.
