Certain files gets corrupted after being copied with RDC

[Kristian]

Hi!

I have a problem with Windows XP SP3 (x86, swedish version) clients when you
try to copy certain file types from a Windows Server 2008 x64 running TS
role. If you create a new XPS file (with the XPS printer for example) and
copy back it to the client over RDP it's file size will increase with a
couple of kilobytes. Larger file = more data will be added. If you try to
open it on the client it won't work. The same thing happens with .ai files
(Adobe Illustrator) and I guess other less common file types also are
affected Word, Excel, PDF, JPEG for example, are all fine. You can copy the
same file from the client to the server and then open it without problem.

Can this be related to TS Easy Print. I know it uses XPS format but I can't
understand why it should affect .ai files.

If you use Windows Vista on the client it works fine. The tested client have
all updates public updates to .NET Framework and Windows. It doesn't matter
if the client connects to the server from the same LAN or Internet.

I've found one that appears to have the same problem:

Thanks in advance!

Hi,

We have a customer that is experiencing the same problem with PDF files. The
file size increase doesn't appear to be random, the file is growing such that
it results in a file size that is exactly aligned with the sectors on the
disk. For instance a particular file grew to be exactly 96KB. Looking at the
general properties for the file shows that the file size is identical to the
size on disk. Also, the few kilobytes that are appended are a copy of a
portion of the same file. This is a critical issue because files are being
corrupted.

Thanks,

Peter

Thanks Peter. The actual size of that .pdf on the server is 87.4 KB taking
up 88 KB on disk.

We RDC'd from XP SP3 client to Server 2008 SP1 (sharing hard drives) and
found the following:

- while browsing remote desktop / machine, edit->copy or right-click->copy
a file then, minimizing RDC window, edit->paste or right-click->paste on
local desktop / machine -- resultant file size was bigger than the original's
(& so resultant file was corrupt)

- while browsing remote desktop / machine, edit->copy or right-click->copy
a file then, from that RDC window, edit->paste or right-click->paste to the
local machine's hard drive (as shown via the remote computer's Windows
Explorer) -- file copied fine and client copy was usable, as expected

It seems almost that the first is akin to a file pull and the latter is like
a file push -- pull fails & push works.

I haven't investigated further -- we simply use push, rather than pull,
though this is an uncomfortable solution.

Thank you for this tip, now we have a work around until a better solution is
available.

Nice find but this doesn't work in our scenerio. We actually use RemoteAPP
which also has this bug. The user is unable to see any local drives to
"push" to.

it looks like Microsoft has a hotfix for this now.
