2.2.3.4 RPC Security Registry Key Values

  • Article

The RPC security registry key values control the supported RPC protocol sequences and the Security Level of the transaction manager endpoints. Both the registry path of the RPC security registry key with these key values, and the protocol used for accessing this key, are version-dependent, as specified in section 2.2.1.2.1.3. For example, in version 6 of the registry protocol, the "TurnOffRpcSecurity" key value is a named value of the "HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC" registry key.
