SQL Server 2008 R2 Multi MSDTC Configuration and Firewall RRS feed

  • Question

  • Hi,

    I have to install multiple MSSQL 2008R2 on a clustered server with a msdtc for each one.

    I have also to define the firewall port to open for them (MSDTCs).

    It seems that MSDTC needs the ports 53 and 135 in order to work and use a dynamic allocation between 1024 and 65000(more or less)  that we can reduce to a fixed range to 100 ports at least.

    But I dont know if this fixed range can be used by each msdtc or if I need a different range for each one. And also if it uses virtual IP or physical IP ?

    Can you confirm or not about the 53/135 ports and explain for the communication port range ?
