Vista: The copy process may stop responding (hang)

[chicagotech]

Problem:
When you try to copy files located in Vista from a computer, the copy process may stop responding (hang), and you may receive a message that resembles the following:
Calculating Time Remaining

0 minutes remaining

Microsoft has a hotfix for this issue. The copy process may stop responding when you try to copy files from a server on a network to a Windows Vista-based computer - http://support.microsoft.com:80/kb/931770/en-us

Two NEW things happen in Vista. It check permissions and I suspect
sniffs for DRM (Digital Rights Management) violations at the behest of
the Hollywood crowd. Add in that it can open an absurd number of
handles to process the task, no wonder it often bogs down. That
something is seriously wrong can be confirmed by moving a few files
totaling 1 GB or so, then trying to copy/move a few hundred files
totally the same amount. Generally it will take MUCH longer in the
second example. This confirms the routine is poorly written and is
wading through needless layers of bloated code.

Two things can help:

1. Apply the hotfix I wrote about months ago. KB 931770
http://support.microsoft.com/default.aspx/kb/931770

There are several web sites you can download it from
without begging Microsoft.

2. Be sure all your non root drives have the right permissions,
which in general means you the user (as you logged in) have
full rights.

My experience and I move 50-80 GB worth of files around daily is this
helps get past the bottleneck. While not always for reasons unknown, I
average between 20-35 MB a second transfers which is on a par with XP.
Without the above two steps the speed was often an absurd 1.5 MB or
less. You can see how fast the files transfer by clicking on the
little arrow in the copy/move window that pops up once you start the
process.

To turn 'Calculating Time Remaining' off, open Control Panel > Programs and features > Turn on or turn off Windows features and uncheck "Remote Differential Compression".

Also you may try to disable Vista TCP/IP "Receive Window Auto-Tuning " that may slow the speed.

To disable it, open a command prompt and type:

netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled

[chicagotech]

I have tried to disable auto tuning level and the rss as described.
Also downloaded the KB931770 file that's refered to in the article from
difrent sites, but it just says that i does not apply to my system.
This is maybe made prior to SP1?

So still got the same problem

>> Disabled autotuninglevel
>> Unchecked IPV6 on networkcards
>> Installed newest networkdrivers from Dell.
>> Clean install of Vista Enterprise with SP1
