Is your IaaS system built from Clone? If so, you will need to uninstall and reinstall MSDTC with an msdtc -uninstall and mstdc -install in powershell respectively. Also, look at your SQL server and make sure all the MSDTC setting are set correctly that your firewall service is enabled but that your firewall is off. Also, check the timeout settings on your SQL Instance in the Configuration Manager.
