JSI Tip 7242. MSDTC fails to mutually authenticate when the computers are NOT in the same domain?

When you use Microsoft Distributed Transaction Coordinator for communications and for distributed transactions between two computers that are NOT in the same domain, the mutual authentication may fail.

To workaround this bug, turn off RPC security:

1. Copy / Paste the following to a TurnOffRpcSecurity.reg file:

REGEDIT4

\[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\Security\]
"TurnOffRpcSecurity"=dword:00000001

2. Merge the TurnOffRpcSecurity.reg file with the registries, or run regedit /s TurnOffRpcSecurity.reg.

3. Restart the computers.
