Hi All,

On Win2003 I have created a virtual channel to send data from client
to server by writing an add-in. This add-in works fine for new session
as well as reconnected session, on win2003.
But when I use same add-in while connecting to longhorn
server then for new session virtual channel works perfectly but when I
disconnect this session and again reconnect it then
"WTSVirtualChannelWrite" on server application fails for reconnected
session with error 1. ie. Incorrect function.

So can any one tell me the reason for this problem. Is there
any specific setting to do on terminal server, so that existing
virtual channel works correctly as that of on win2003.

Please guide me.
Any help will be appreciated.


Thanks
Amit
 
Re: Virtual channel reconnect on longhorn (Win2k8)

Are you re-opening the channel when reconnected? Longhorn requires the
channel to be reopend when reconnected (includes auto-reconnect) which
differs from Win2k3

Thanks

Rong

Hi Rong,

Thanks for your valuable help.
Can you give me any MSDN or any other link where you mentioned point
is explained in more detail .
And do you have any idea why longhorn changed this behavior since
2k3.

Thanks
Amit
