"The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025)"
This message appears when MS DTC is not enabled for remote/network transactions. It would occur when trying to initiate a DTC controlled transaction involving more than one machine.
While DTC has been configured properly on the requesting machine, one of the remote respondant has not been configured to accept remote or network requests.
