What UUID's to specifiy for Firewall filtering on Windows 2008 for MSDTC


  • I have 2 machines that need to take part in a distributed transaction using MSDTC. In between these machines sits a firewall that needs to be configured to allow the network traffic to flow (fairly typical :-) ). There seems to be 2 methods for configuring the firewall:

    1. Configure MSDTC to use a fix set of ports ( e.g. 5000-5020 ) and open these ports up on the firewall
    2. Specify the UUID's for MSDTC communication.

    Option 2 is the preferred option (reasons are outside of the scope of this question)

    The following article states the UUID's to configure on the firewall to enable MSDTC communication but does not give the windows server version this applies to.

    Has anyone configured a firewall with these UUID's with Windows 2008 servers and successfully managed to 'chat' between the boxes?

  • Hi,

    Thanks for posting in Windows Server Forum.

    From your description, it appears that the issue related to MSDTC services. However, I am not an expert about it. In order to get more effective suggestion, I would suggest that we post this question at Transactions Programming forum. There you can have more effective comments with other experts who familiar with this topic. Your understanding is highly appreciated.
