Updated: December 3, 2008

Applies To: Windows Server 2008 R2

yellow

Message Queuing operation provides message authentication, message encryption, dead-letter queues, security settings, and other basic features. If Message Queuing has problems with any of these features, proper Message Queuing operation may suffer.

Event Details

Product: Windows Operating System
ID: 2195
Source: MSMQ
Version: 6.1
Symbolic Name: EVENT_WARN_UNAUTHENTICATED_MESSAGE_REJECTED
Message: Message Queuing could not authenticate a message sent to queue %1. The message was rejected because the queue only accepts authenticated messages. A negative arrival acknowledgement will be sent if requested by the sender. This event is logged at most once per %2 seconds. To change this setting, set \HKLM\Software\Microsoft\MSMQ\Parameters\Event2195 registry value to desired time in seconds.

Resolve

Confirm that messages are authenticated and that the sending computer has a valid certificate

Because the queue accepts only authenticated messages, messages that are sent to the queue must be authenticated and signed with a certificate, which is registered in Active Directory Domain Services (AD DS).

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To confirm the presence of user certificates:

  1. On any computer in the domain, click Start. In the search box, type compmgmt.msc, and then press ENTER.
  2. Enter administrator credentials, if you are prompted, and then continue through the User Access Control messages.
  3. Navigate to the Message Queuing console tree. Click Services and Applications, and then click Message Queuing.
  4. Right-click Message Queuing, and then click Properties.
  5. Click the User Certificate tab.
  6. Click View.
  7. Determine whether the computer sending the unauthenticated messages is in the Personal Certificates list.
  8. If the computer is not in the list, a certificate was not registered.
  9. You can fix this by performing steps 1 through 7 on the computers on which the certificate was not registered. For step 6, click Register instead of View.

For more information about signing messages, see Message Authentication (http://go.microsoft.com/fwlink/?LinkID=104732).

Verify

Verify that the MSMQ Service is installed and running.

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the MSMQ Service is installed and running:

  1. Open the Services snap-in. To open Services, click Start. In the search box, type services.msc, and then press ENTER.
  2. Locate the Message Queuing service, and confirm that the value in the Status column is Started.
