CAUSE
This problem may occur when one of the following conditions
is true:
- You use a network address translation (NAT) firewall.
Message Queuing cannot be used with a NAT firewall.
- Your computer changes its IP address when you start your
computer.
- You have multiple clients that use same Message Queuing
GUID because the operating system was cloned or ghosted without using the
System Preparation tool (Sysprep.exe).
Message Queuing transactional messages (exactly one time and
in-order delivery) are based on sequence IDs (SEQIDs). In this case, the SEQID
was never sent from the computer that is associated with the SEQID. Instead of
rejecting the acknowledgement as not valid, the sending system tries to process
the acknowledgment as valid. This corrupts internal Message Queuing lists and
eventually causes the access violation. The hotfix that is described in the
"Resolution" section of this article rejects the acknowledgement. Therefore, it
prevents the access violation. This hotfix only prevents the access violation.
