Unauthorized Error during Processing Outbound Message in XI

Question

I have configured a scenario that whenever there is a file of certain filename it will trigger one of the out bound message.
But the following error occured during processing of the out bound message:
Error Msg: Failed to transmit message due to  Unauthorized
May I know how/where to set the acess right?
StackTrace is as follow:
find . -type f -exec grep "61abff41-dd01-11dc-c53d-001a4b053868" /dev/null {} \;
./defaultTrace.3.trc:#1.5#001A4B053868006E0000001600004E4900044651CF729F25#1203217093532#com.sap.aii.af.ra.ms.impl.core.queue.SendConsumer##com.sap.aii.af.ra.ms.impl.core.queue.SendConsumer.onMessage(QueueMessage, boolean)#J2EE_GUEST#0####2d915860dd0411dccdbb001a4b053868#SAPEngine_Application_Thread[impl:3]_116##0#0#Error##Java###Failed to transmit message due to .#2#61abff41-dd01-11dc-c53d-001a4b053868(OUTBOUND)#com.sap.aii.af.ra.ms.api.RecoverableException: Received HTTP response code 401 : Unauthorized#

Hi,
>>I have configured a scenario that whenever there is a file of certain filename it will trigger one of the out bound message.
What does it mean
Procedure to trigger any of the interface.
1) Develop IR Objects according to the scenario
2) Develop ID objects according to the scenario.
3) In the Sender Communication channel Specify the name of the file and the Source directory that the outbound interface shld pick to process it in XI
4)In the Rec Channel  Similarly specify the name of the file and the Target directory to place the file.
If u specify the file name in the sender channel means according to that file name corresponding interface will be run.
