Error: 'New transaction cannot enlist in specified transaction coordinator.' (NETIQKB50360)

Distributed Transactions Coordinator (DTC) guid identifier does not work.

To eliminate the duplicate ID, either:

• Use GuidGen to create a new GUID and update DTC registry with the new GUID as described in the Microsoft Knowledge Base article, Troubleshoot MS DTC Firewall Issues, which can be found at http://support.microsoft.com/default.aspx?scid=kb;EN-US;306843.
  or
• Reinstall DTC:
  • Windows 2000: Perform the steps in the Microsoft Knowledge Base article, How to reinstall MS DTC for a nonclustered Windows 2000 Server, which can be found at http://support.microsoft.com/default.aspx?scid=kb;EN-US;279786.
  • Windows 2003: Perform the steps in the Microsoft Knowledge Base article, How to reinstall MS DTC for a nonclustered Windows 2000 Server, which can be found at http://support.microsoft.com/default.aspx?scid=kb;EN-US;279786 except when you reinstall MSDTC, use the command msdtc -install. Also, enable Network Access as described in You Receive Error 7391 When You Run a Distributed Transaction Against a Linked Server, which can be found at http://support.microsoft.com/default.aspx?scid=kb;en-us;329332
  • Windows NT: Perform the steps in the Microsoft Knowledge Base article, Reinstall MSDTC for a non-clustered Windows NT 4.0 Server, which can be found at http://support.microsoft.com/default.aspx?scid=kb;EN-US;250987.
    

One of the database machines was duplicated or cloned from another machine using a product such as VMWare or Ghost. As a result, the DTC GUID is not unique and the DTC instance cannot be uniquely identified. For more information about this problem, see Do Not Disk Duplicate Installed Versions of Windows from  http://support.microsoft.com/default.aspx?scid=kb;EN-US;162001.
