Problem with Virtual Channel

[yoda.ch...@gmail.com]

Good morning,
I have a problem with a Virtual Channel application developed in C++. I

use the windows API and the RDP protocol.
I developed two different virtual channel (two dll). I registered them
as described in:

http://windowssdk.msdn.microsoft.com/en-us/library/ms728010.aspx

Registri key:

HKEY_CURRENT_USER\Software\Microsoft\Terminal Server
Client\Default\Addins\Channel1
and
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server
Client\Default\Addins\Channel2

I set the "Name" string for both.

The problem is that only one of the two dll is loaded (the first
one).
Where I'm wrong?
The client is a windows XP system and the server is Windows 2003
server.
Thank you for any hint.
Fabiana
