MSDTC encountered anerroron yourPC? Don’t not worry, we have got the right fixes for you. Some Windows users reported gettingerrorswhen they enable the WCF-Custom receive location. Theerroris usually displayed in this format:MSDTC encountered anerror(HR=0x80000171) while attempting to establish a secure connection with system.

Microsoft’s Distributed Transaction Coordinator (MSDTC) enables you to control transactions coordination between resource managers and applications. Also, while MSDTC relies on the network topology of the underlying components, a transaction can span multiple DTCs throughout your network.

However, Network DTC Access must be enabled on all MS DTC instances that are participating in the transaction; this enables transactions to be coordinated across the network.

For example, if a remote computer attempts to update a SQL database by using MS DTC transaction while Network DTC is disabled, the transactions will fail; hence, the MSDTC encountered anerrorprompt. The Windows Report team has compiled the applicable solution for thiserrorproblem.
