Unable to copy some but not all files to Resara shares from W7 - Not a Resara problem after all

[Robinson Mitchell]

I am using Windows 7 clients joined to a Resara AD Domain and using
Resara shares. After using the Resara server as a file server for
some time, I was surprised to find that it was impossible to copy some
files to shares on the Resara server. At first I thought this was a
Resara issue. It turned out that this is a Windows problem, not a
Resara problem, but I'm posting the issue here for the information of
the group.

Steps to reproduce symptom: Attempt to copy a file downloaded from
the Internet to a Resara file share.

Symptom: File begins to copy, but does not complete, yielding a Copy
File error window results with the following error text:

"An unexpected error is keeping you from copying the file. If you
continue to receive this error, you can use the error code to search
for help with this problem."
"Error 0x80070032: The request is not supported"
The error box has "Try again" and "Cancel" buttons.

Cause: Windows 7 NTFS volumes store zone information in Alternate
Data Streams on files. Files downloaded from the Internet are blocked
by Windows 7. The file must be unblocked to allow copying it to a
Resara share (or presumably any other share).

Procedure to unblock:
(GUI) Right-click the blocked file in Explorer, choose Properties.
Click the Unblock button at the lower right. File will now copy
normally.
(Command Line) Use the SysInternals Streams tool to delete the ADS
information:

<code>
streams -s -d [path to directory where you want all files unblocked]
</code>

I hope this is helpful.
