DSOFile.dll to read properties from network drive

[Nautilus]

I am writing an application in ASP.Net which generates a
list of files from a shared network folder using
DirectoryInfo class and then I use the wonderful control,
<a href="http://support.microsoft.com/?
kbid=224351">DSOFile.dll</a>, provided by Microsoft to
gather the document properties like Author, Title etc and
show along with file list. I can generate the file list
from shared network folder but I am not able to read the
document properties from network folder. I provide the
filename to DSOFile control as
docProps = propReader.GetDocumentProperties(\\<machine>\<fold er>\<file>)
.. When I provide the local
machine drive(like E:\Folder\file), it works fine but with
network folder, I get the error: Exception from HRESULT:
0x80030002 (STG_E_FILENOTFOUND).
Can someone please tell me how to resolve this issue?
Thanks,
