Hi Paul, Got the reason on why the message exit was working on the sender side of NT but was not working on the receiver side which was on AIX. The code which was setting the MQRFH2 header part of the message was setting the values in the UNIX way for the MQLONGs which was Big Endian and the NT side was not able to understand the MQRFH format's values in. That is why the "get" through the MQExplorer was giving an unexpected error. But i was able to get using the amqsgetc sample program by MQSeries.
I tried setting the values in the MQRFH2 header in the Little Endian format and then I was able to see the message in MQExplorer. Both ways I am able to get the message using amqsget sample programs but i can view it in NT only when I have the values in Little Endian for the MQRFH2 header... Thanks for the help Paul.
