Reinstall MSDTC

Reinstall the Distributed Transaction Coordinator (MSDTC) with the following steps (Win2k/WinXP/Vista/Seven):

Execute the following commands:

  • Net stop msdtc
  • Msdtc -uninstall

    • Delete folloqing registry keys:

    [HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \MSDTC]
    [HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \MSDTC]

    Execute following commands:

  • Msdtc -install
  • Msdtc -resetlog
  • Net start msdtc

    • [tab:Reset Log]

    Reset Recovery Log

    Distributed Transaction Coordinator (MSDTC) uses the following log file for storing transaction-related recovery information along with all other MS DTC recovery information (WinNT4 also uses Dtcxatm.log).

    %SystemRoot%\system32\DTCLog\MSDTC.LOG

    If the location of the log file is faulty (non existing or no permission) or the MSDTC.LOG is corrupted, then it will keep the service from starting and give errors like:

    Event ID : 7024
    Source : Service Control Manager
    Description: The MSDTC service terminated with service specific error 3221229584.

    Event ID : 4163
    Source: MSDTC
    Description: MS DTC log file not found. After ensuring that all Resource Managers coordinated by MS DTC have no indoubt transactions, please run msdtc -resetlog to create the log file.

    To reset the [gs log]-file:

    If possible start the computer in safe mode.

    Open the %SystemRoot%\System32\DTCLog folder. (Unless you have changed the default location)

    If a Msdtc.log file exists in the [gs folder], rename it to Msdtc.old.

    Use Notepad to save an empty file as Msdtc.log in the folder.

    Open a CMD [gs prompt] and type:

    msdtc -resetlog

    and press Enter.
