Error message when you try to start a transaction in MS DTC: "New transaction cannot enlist in the specified transaction coordinator" (922430)

Important This article contains information about how to modify the registry. Make sure to back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs.

SYMPTOMS

Consider the following scenario. You have a client computer that communicates with a server computer. Microsoft Distributed Transaction Coordinator (MS DTC) is installed on both computers. One or more of the following conditions are true:

You restart either of the computers.
You restart MS DTC on either of the computers.
The computers are in different domains.

In this scenario, you receive the following error message when you try to start a transaction in MS DTC:

New transaction cannot enlist in the specified transaction coordinator (0x8004d00a)

Additionally, the first transaction fails. The subsequent transactions succeed for a while. However, the subsequent transactions may fail again. If the subsequent transactions fail, you receive the following error message:

New transaction cannot enlist in the specified transaction coordinator (0x8004d00e)

Note This problem is more likely to occur when you use Microsoft Windows Server 2003 Service Pack 1 (SP1) together with Kerberos authentication.

CAUSE

This problem may occur when the MS DTC connection between the client computer and the server computer is closed. For example, an idle time-out, a remote procedure call (RPC) time-out, or the firewall may close the MS DTC connection between the client computer and the server computer. When a new transaction request occurs, the client computer must reestablish the MS DTC connection with the server computer.

When the client computer tries to reestablish the MS DTC connection with the server computer, the client computer sends a packet. Then, the client computer waits for a bind packet response from the server computer. By default, the client computer stops the transaction if the client computer does not receive a response from the server computer in 4 seconds. The response from the server computer may be delayed because of network latency issues or authentication delays. When the response from the server computer does finally reach the client computer, the subsequent transactions succeed.

RESOLUTION

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To make sure that you are experiencing the problem that is described in this article, confirm that the MS DTC transaction trace log file contains the following data:

;eventid=TRANSACTION_PROPOGATION_FAILED_CONNECTION_DOWN_FROM_REMOTE_TM ;tx_guid=f11cd9c9-7b8a-41e3-a904-4840123bacf7 ;"failed to propogate transaction to child node 'ComputerName' because the connection with the remote transaction manager went down"

Notes

In this data, the word "propogation" is a misspelling for the word "propagation." The word "propogate" is a misspelling for the word "propagate."
For more information about how to enable and view MS DTC transaction trace data, see the "More Information" section.

If the MS DTC transaction trace log file contains this data, follow these steps:

Click Start, click Run, type regedit, and then click OK.
Locate the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC
Right-click MSDTC, point to New, and then click DWORD Value.
Type CmMaxNumberBindRetries, and then press ENTER.
Right-click CmMaxNumberBindRetries, and then click Modify.
Click Decimal.
In the Value data box, type 60.

This value increases the length of time that the client computer waits for the bind packet response from the server computer. This value is double the number of seconds before the client computer stops the transaction if the client computer does not receive the bind packet response. For example, a value of 60 equals 30 seconds.

Note The value of 60 is only a recommended value. Additional testing on your configuration may be required.
Click OK.
Restart the computer.
