Webdav with IIS6

I set up a webdav server with W2003 and IIS6, all up-to-date.
I use a Windows 7 client to download/upload files. Works fine, but some files won't copy:
- thumbs.db
- folder.ico
- desktop.ini
Here I get a "open error, cannot find file".
Is this because the files are system files? What can I do to copy them without changing the attributes.

Also, some file with a large size can not be up-/downloaded: "open error, filesize limit exceeded".
What are these limits and how can I change them? Are there maximum values?

The copy process goes on for some times, but then freezes. Is WebDav not a very reliable protocol? What can I do to troubleshoot the connection (logs etc).

how did you setup your webdav folder ?
did you do it through "Add Network Location" ?

because i can open it up from the browser but not from the mapped network drive.

These three files are not required to download or backup.

@jjoz:In Windows 7 I used "Add Network Connection" in explorer (Computer) and by that it's mapped to a driveletter.
When I open the webdav folder in a browser, I only have a directory listing, no ebdav functionality.

@kadadi_v: I thought so about the files, thank you for the links. But about the realibility of WebDav, the author says WebDav is no good, and the person commented to it tells the opposite.

In the meantime, my biggest problem is the filesize. When this is to big, copy is not possible.

yes, you are right man, and you are not alone as well,
I have successfully mapped the WebDav folder under Windows XP but not under Windows 7.

@kadadi_v:Thank you for the links, but I'm not looking for an alternative yet. The other link descibes problems I don't have, not the problem with the filesize.

@jjoz:But I do, I have a active mapping in Windows 7, workfing, only have the filesize problem as described.

Hi LucF,

The first you offered is exactly the same post as I included in my reply 21/09/10 12:25 PM, ID: 33723758. This doesn't work.

However, your second solution, Microsoft article http://support.microsoft.com/kb/900900/en-us is the solution for my problem. So concluding, it is not a server issue, but a client issue. The client blocks down-/uploads. After chaning the registry, I can transfer max larger files.
However, because the registry value is a DWORD, the maximum of FileSizeLimitInBytes is limited to aboud 4,4 Gb. This is enough for me, but WebDav cannot be used for larger files.

Keep in mind, while copying these large files, the progress inicator goes nuts. It finished copying 1 Gb in 10 seconds over a 4Mbps line :-), and stayed on 100% for a few hours after that.
When the dialog disappeared, only about 75% of the file was copied. I just waited for an hour an looked again. Now the was was copied up to the last bit. Keep this in mind when copiing large file with WebDav.
