Set MSDTC properties using COMadmin

I am trying to automate the configuration of MSDTC properties in C #, I have to set the MSDTC security configuration (Component Services -> Computers -> My Computer -> Properties -> MSDTC -> Security Configuration),

• "DTC Network Access" - Enable
• "Allow remote clients" - enable
• "Allow remote clients" - enable
• "Allow remote administration" - enable

In the section "Transaction Manager Management"

• "Allow incoming" - enable
• "Allow outgoing" - enable
• No authentication required
• Enable XA Transactions - Enable

i'am can set local machine properties using comadmin class,
