Distributed transactions fail when IPv6 is not working on a server that's running Windows Server 2008 R2

Applies to: Windows Server 2008 R2 DatacenterWindows Server 2008 R2 EnterpriseWindows Server 2008 R2 for Itanium-Based Systems

Symptoms


When IP version 6 (IPv6) is not working on a server that's running Windows Server 2008 R2, Distributed Transaction Coordinator (DTC) Transaction Internet Protocol (TIP) transactions don't fall back to IP version 4 (IPv4) as expected. Therefore, the distributed transactions fail over the network. Additionally, you receive the following error message:

This transaction manager failed to establish a connection with another TIP transaction manager. (Exception from HRESULT: 0x8004D01F).

Cause


This problem occurs because of incorrect parameters that are passed to the getaddrinfo API. Because of this error, IPv6 is selected. And if IPv6 fails, the transactions fail generally.
