Messages Sent with Direct=TCP May Be Rejected After IP Change on Target Computer (271646)


The information in this article applies to:

  • Microsoft Message Queue Server (MSMQ) 1.0
  • Microsoft Message Queuing 2.0
This article was previously published under Q271646

SYMPTOMS

A computer that is running Microsoft Message Queuing does not accept messages that are sent by using a Direct=TCP format name if the TCP/IP address has changed. This problem occurs most frequently when a computer connects to a network through Remote Access Service (RAS).

CAUSE

MSMQ binds to the available IP addresses on a computer when the service is started. The Message Queuing queue manager does not recognize IP addresses that change after the service is started. When a message is passed to the Message Queuing queue manager, the queue manager checks the target IP address in the message to determine if the queue manager recognizes that IP address. If the IP address is not known, the message is not accepted.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Message Queuing no longer checks the known IP address table when a message that was sent by using a Direct=TCP format name arrives. Message Queuing assumes that the message belongs to the computer.
