MSMQ: Messages That Are Sent By Using the Direct=TCP Syntax Are Rejected (306416)

SYMPTOMS

When you use the Direct=TCP syntax to send messages to client computers that are running Microsoft Windows 95 or Microsoft Windows 98 and that are remotely connected to a network, the messages are rejected.

For example:

qinfos1.FormatName = "Direct=TCP:10.10.10.10\testq"

CAUSE

The queue manager binds to IP addresses that are assigned when the queue manager starts, which occurs during the boot process for Windows 95 and Windows 98. If the computer uses a remote access connection, a new IP address is assigned and that IP address may be used by applications that use the Direct=TCP FormatName syntax to send message to the client computer. This IP address is unknown by the queue manager at the time that the message arrives and the queue manager rejects messages that are sent to it that do not belong it.
