title: MSDTC and firewall
body: <p>We are using MSDTC for SQL transactions.
  I am having issue with setting up firewall for MSDTC to work.
  The application and SQL are running on separate machine.
  Currently MSDTC is working if i turn off firewall on application server.
  I think there should be someway to add exception to the firewall setting for some ports.
  So that firewall can still be ON and DTC will not have any issues.
  I am not sure of the ports to add in firewall setting (I did try adding port 135 with no success)</p>
