    From server B Distributed transaction work in Server A only.

    From server c Distributed transaction work in Server A only.

Problem: Distributed Transaction does not work between server B and C.

Answer 1

May be you have problem with configuration of your firewalls on A\\B\\C servers. You can try to temporally disable firewalls to check this. See following link for more details about "Enable Network DTC Access".

Answer 2

This issue was due to same unique identity in MSDTC of server B and server C. 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. Note: In Windows 2008 use Administrator command prompt, service must be stopped and you must reboot the server.
