the promote method returned an invalid value for the distributed transaction

Question

Hello,

Getting the above error when using transaction scope .We use wcf services and this error has occured when we have changed to windows server 2016.

Answer 1

Hi,
As far as I know, this error primarily indicates that the transaction operation has been promoted to a distributed transaction operation, but because the distributed operation depends on MSDTC. This dependency may have caused the error. For example, MSDTC service is not enabled, please refer to the following steps to enable MSDTC
Enable DTC service,

Control panel, administrative tools, Component service.

Add firewall rules. Enable inbound rules and outbound rules for 135 port and “C:\Windows\System32\msdtc.exe” application.
Besides, please refer to the below discussion, it might be useful to you.
