MSDTC Static Port / Port Assignment


  • Hello,

    I have some Windows 2008 R2 servers located in my DMZ that will be running MSDTC and making calls to a SQL 2008 (Windows 2008 R2) server on the internal network.

    I understand the new dynamic RPC port range for Windows 2008 is 49152-65535.

    I've also read where you can now assign a static port to the MSDTC service (using the ServerTcpPort key value) in lieu of opening up the dynamic RPC port range (or a subset thereof) on the DMZ firewall.

    What are the drawbacks (if any) of assigning the MSDTC a static port? Can (How does) the MSDTC handle multiple connections if it is assigned a single static port?

    Thank You
