MSDTC Issue : Duplicated CID

Recently while overseas at work, I was setting up a distributed environment for a client of mine.

Everything was working fine till I started configuration for the MSDTC (Distributed Transaction Coordinator) on 2 of the Virtual Machines. Both machines just refused to pass data or communicate with each other.

Upon viewing on the Event Viewer, I notice this error.

Duplicate CID.

We found out that the infra guys just copy this VM and change the computer name for it.


1. Start Command Prompt as Administrator

2. Enter and Run the following : MSDTC -uninstall

3. Restart your OS.

4. Again Start the Command Prompt as Administrator

5. Enter and Run the following : MSDTC -install
