Event ID: 4101 - Same unique identity as the local MS DTC

Last Updated: 1/8/09

Problem:

Event Type:	Error
Event Source:	MSDTC
Event Category:	CM
Event ID:	4101
Date:		1/8/2009
Time:		1:15:26 PM
User:		N/A
Computer:	COMPUTERSERVER
Description:
The local MS DTC detected that the MS DTC on COMPUTERCLIENT has 
the same unique identity as the local MS DTC. This means that the
 two MS DTC will not be able to communicate with each other. 
This problem typically occurs if one of the systems were cloned 
using unsupported cloning tools. MS DTC requires that the systems
 be cloned using supported cloning tools such as SYSPREP. 
Running 'msdtc -uninstall' and then 'msdtc -install' from the
 command prompt will fix the problem. Note: Running 'msdtc -uninstall'
 will result in the system losing all MS DTC configuration information.

For more information, see Help and Support Center at 
http://go.microsoft.com/fwlink/events.asp.
Solution:
After cloning a server running these commands on the cloned computer.

net stop msdtc
msdtc -uninstall
net stop msdtc
Run, "services.msc", verify that the "Distributed Transaction Coordinator" is stopped and not listed.
msdtc -install


Also if you get this error when trying to delete a COM+ app:
The requested action cannot be performed because DTC is not running

Reboot and try again.
