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.

Solution:

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
