Recently, two of our clients reported problems while importing files in ADAM that came from a file share. The NtfsStreamException came with a particularly worrying and puzzling mesage: "The request is not supported.". I have included the stack trace below for reference.

Errr... little help?

When we had a look at our code, we found that this exception was linked to the Windows error with the ID 0x00000032 (ERROR_NOT_SUPPORTED), which could mean about anything.

After some searching, we found a knowledge base article issued by Microsoft that talked about the exact same error occurring when a computer running Windows Vista or Windows Server 2008 tries to read a file on a computer not running either of these operating systems.

The knowledge base article further provides a download containing a hotfix that fixed this problem for our customers. Also note that this hotfix is or will be included in existing or upcoming service packs for these operating systems, so only install it when you're actually having the problem as described in this article.

Oh, and before I forget, all of this sweet hotfix goodness is located at http://support.microsoft.com/kb/973278/en-US.
