Resolve

Check XA registry keys

An error condition may have resulted from a problem with a registry key for an X/Open Distributed Transaction Processing Standard (XA) provider. Check that the registry keys are appropriate for your XA provider, and then restart the Microsoft Distributed Transaction Coordinator service (MSDTC).

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

To open Registry Editor on the server and check the XA registry keys:

Caution: Incorrectly editing the registry might severely damage your system. Before making changes to the registry, you should back up any valued data.

  1. Click Start, click Run, and then type regedit. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. Click HKEY_LOCAL_MACHINE, expand Software, expand Microsoft, expand MSDTC, and then click XADLL. Check that the registry key is appropriate for your XA provider.
  3. To change the registry key, in the details pane, right-click the provider information that you want to change, and then click Modify.
  4. Make the required changes to the entry in Value data, and then click OK.

To restart MSDTC:

  1. Click Start, and then click Command Prompt.
  2. At the command prompt, type net start msdtc, and then press ENTER.
