Hello,
Thanks for your post as well as to Robert for the information sharing.
According to your description, my understanding is that: When you copy
large files at a high speed from other computers to Vista machines (within
the same network), the copy process might stop responding and ping from
Vista machines to other computers might return timeout. You have already
tried several methods to fix this issue but with no luck.
If there is any misunderstanding, please let me know.
Analysis:
=============
After some research, I find there are two main reason which might cause the
similar issue. What Robert said was right on the target.
1. There is a known issue on a Windows Vista-based computer, when you try
to copy files from a server on a network, the copy process may stop
responding (hang). There is a hotfix available for this kind of issue.
2. Another reason which might cause similar issue is Vista Auto-Tuning
feature. Auto-Tuning feature is a new introduced feature in Windows Vista.
What it does is to adjust the receive windows size continually based upon
the changing network conditions. However, sometimes auto-tuning feature
might cause network time-out problems with some applications and routers.
Suggestions:
=============
1. Install the hotfix provided in KB 931770
The copy process may stop responding when you try to copy files from a
server on a network to a Windows Vista-based computer

2. Turn off Auto-Tuning feature on Vista and have another test.
To turn off Auto-Tuning feature, please do as follows:
2.1 Click on Start button.
2.2 In the Search box, type in Command Prompt. Command Prompt will show up
in the search results.
2.3 Right click on Command Prompt icon and select Run as administrator.
2.4 Enter the admin credential and you are ready to go.
2.5 Enter the following command to disable auto-tuning
netsh interface tcp set global autotuninglevel=disabled
Please note, as this issue is a performance issue, it usually needs
advanced troubleshooting steps to isolate the problem, including enabling
trace log, checked build, remote debug, dump file analysis, even with these
steps, the in-a-basket solution may not be figured out in a timely manner.
Saying that, newsgroup is not the right media to work on such performance
issue. If the above methods do NOT help, I recommend that you contact
Microsoft Customer Service and Support (CSS) directly for further
investigation. For more information on available CSS services, please click
