MSDTC on Windows 2012 Standards edition

Hello Friends,

We have migrated our Prod server to Windows server 2012 Standards editions.

and enabled MSDTC but still getting below error 

Error :-

1. 1.     The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B)

1. 2.     The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025)

we have enabled MSDTC and restarted the server but it not working.

can you please help me.
