Configuring MSDTC to listen on a specific port

You can configure the Microsoft Distributed Transaction Coordinator (MSDTC) to listen on a specific RPC server port

About this task

To configure DTC to listen on a specific RPC server port you add or modify the following registry key value.

Procedure

  1. Open a regedit window and add or modify the following:
    • Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\
    • Name: ServerTcpPort
    • Type: REG_DWORD
    • Value: <Numerical value of the port on which DTC is to listen>

      For example, 0x00001f90 = decimal value port 8080

  2. Access the Control Panel > Administrative Tools > Services window and restart the Distributed Transaction Coordinator service for the changes to take effect.
  3. To confirm that the MSDTC service is listening on the configured server port, at a command prompt enter netstat.exe.
