I am having a problem with I think impersonation, but I could be mistaken.
I have an IBM XMS consumer, consuming data from a queue. Works fine. In order to be granted access to the queue the service needs to be running as specific user, for this I have implemented .Net impersonation. On all systems I am able to get the queue running, the problem occurs when there is a need to restart.
To test restart I have placed a simple if(messages == 500) throw... which triggers cancellation, disconnection and reconnection.
I installed the application as a Windows service to my local machine, it connects (using impersonation), reaches 500, throws, disconnects, reconnects and continues to process messages. However when I run the same code on our server it fails while trying to create a queue connection. Here is the error:
