Based on the timing of one minute before you see the failure, it sounds to me like you're running into the
SendReceiveTimeoutInSec threshold for the WebDAV redirector on your client computer, which is set to one minute by default. If you take a look at the "WebDAV Redirector Registry Settings" section of the following walkthrough, that contains
the details for that timer:
To make it easier to modify those settings, I wrote a simple user interface for the WebDAV redirector settings that I describe in the following blog post:

Did you restart the WebClient service on your Vista Computer after you made the registry changes? Those changes are only reflected after the service has been restarted.

Ah, then you're probably running into the Request Filtering limits. Here's how you locate and modify those settings:
This is what the dialog looks like:
You need to change the value of the Maximum allowed content length (Bytes) field.

What is the Microsoft Support link or Service Bulletin Article for this 2593591 ?

Sorry for the delayed response, I was out of town for the past week. ;-]
That hotfix comes into use when large numbers of properties are set on files on the server; this usually occurs when files are uploaded, and generally occurs with a custom WebDAV client. So it probably won't help your problem with large file uploads.
I'm not 100% certain, but the delayed right-click when using the Windows WebDAV redirector might be caused by the file being downloaded in order to retrieve properties; I'll check on that.

You might roll back from Hot Fixes and changes you have made up to this point.
The registery key "NoRemoteRecursiveEvents registry setting" may not apply for Web Dav.

I hope this is the correct ballpark :D.
The reason for the links is the common information for the Registery changes.
Do not request the "Hotfixes" or install them unless they are for the indicated Windows Systems.
The only risk to your system(s) is incorrect Editing of the registery. Before using the Registery Editor use System Restore.
Then also use export in the Registery Editor for the Key or Branach being changed.
Save the current Branch and Key Edit to the Registery Editor Favorites,

Looks like the wrong ball park. I was looking at the UI and Visual parts.
Best to wait until the report for the failure tests is done.:D.

Good morning John,
Thanks for your feedback, very good your research. I will return of my vacation on Jan, so that I can take your information and mix with I already have. I have a ticket open with Microsoft as well, but it's recent.. they are still getting more information
about the problem.
If I discover something about this case, I let you know.

maybe I have some information for you.
System: Windows SBS 2011 Standard + IIS 7.5 hosted by an ISP Client: Windows 7 Prof
I'd the same problems like you. the data copying hangs up in the end of the copy process or it freez ... I could not copy a folder with 30mb or 40mb because the copy job broke down ...
to copy files larger then 50mb I had set the param "Maximum allowed content length (Bytes)" up to 4gb inside the iis request filtering. after this configuration everething works well. I can copy small files, big files and folders with many many subfolders
and a lot of files.

I have the revision history for Webdav.dll on my blog site and this includes a link to the requestable Microsoft Hotfix 2503820 - FIX: Memory leak in the W3wp.exe process for a WebDAV website when many WebDAV clients upload files, download files, or access
file directories in WebDAV 7.5
Perhaps this may to help address some of the performance issues you are facing with WebDAV
Hope it helps

Any updates to this thread? You've become a ghost howardjnl, and your threads and input have been highly useful in helping me understand some of the things that WebDAV is doing behind the shadows. Please don't be one of those people that said they solved
their issue yet didn't come back to tell us what did the trick :)
Jan 17, 2013 02:56 PM|JPalm|LINK
^Agreed. Experiencing the same issue. Tried the tweaks suggested here to no avail.

Well, I finally determined two ways to address the problem:
1. Make the registry size limit change recommended and use Bitkinex instead of Windows based WebDAV, OR
2. Upgrade to Windows 8. I took advantage of the $39.99 deal at MS to upgrade to Win 8 Pro and seems to have resolved my problems. Go figure :-)
