+#             testing is needed to verify it is working as expected
+#
+#   Best way to learn how to use these calls is to grab the protocol standard

+#   Since DCOM is like an OO RPC, instead of helper functions you will see the 
+#   classes described in the standards developed. 
+#   There are test cases for them too.

+#
+#   Some calls have helper functions, which makes it even easier to use.
+#   They are located at the end of this file.
+#   Helper functions start with "h"<name of the call>.
+#   There are test cases for them too.

+#
+#   Best way to learn how to use these calls is to grab the protocol standard
+#   so you understand what the call does, and then read the test case located
+#   at https://github.com/SecureAuthCorp/impacket/tree/master/tests/SMB_RPC
+#
+#   Some calls have helper functions, which makes it even easier to use.
+#   They are located at the end of this file. 
+#   Helper functions start with "h"<name of the call>.
+#   There are test cases for them too.

+#   so you understand what the call does, and then read the test case located
+#   at https://github.com/SecureAuthCorp/impacket/tree/master/tests/SMB_RPC
+#
+#   Some calls have helper functions, which makes it even easier to use.
+#   They are located at the end of this file. 
+#   Helper functions start with "h"<name of the call>.
+#   There are test cases for them too.

+        # in the query of the HTTP request. The target RPC Server must be the ncacn_http
+        # service.
+        #
+        # The utilized format: /rpc/rpcproxy.dll?RemoteName:RemotePort
+        #
+        # For RDG servers, you can specify localhost:3388, but in other cases you cannot
+        # use localhost as there will be no ACL for it.
+        #
+        # To know what RemoteName to use, we rely on Default ACL. It's specified
+        # in the HKLM\SOFTWARE\Microsoft\Rpc\RpcProxy key:
+        #
+        # ValidPorts    REG_SZ   COMPANYSERVER04:593;COMPANYSERVER04:49152-65535
+        #
+        # In this way, we can at least connect to the endpoint mapper on port 593.
+        # So, if the caller set remoteName to an empty string, we assume the target
+        # is the RPC Proxy server itself, and get its NetBIOS name from the NTLMSSP.
+        #
+        # Interestingly, if the administrator renames the server after RPC Proxy installation
+        # or joins the server to the domain after RPC Proxy installation, the ACL will remain
+        # the original. So, sometimes the ValidPorts values have the format WIN-JCKEDQVDOQU, and
+        # we are not able to use them.
+        #
+        # For Exchange servers, the value of the default ACL doesn't matter as they
+        # allow connections by their own mechanisms:
+        # - Exchange 2003 / 2007 / 2010 servers add their own ACL, which includes
+        #   NetBIOS names of all Exchange servers (and some other servers).
+        #   This ACL is regularly and automatically updated on each server.
+        #   Allowed ports: 6001-6004
+        #
+        #   6001 is used for MS-OXCRPC
+        #   6002 is used for MS-OXABREF
+        #   6003 is not used
+        #   6004 is used for MS-OXNSPI
+        #
+        #   Tests on Exchange 2010 show that MS-OXNSPI and MS-OXABREF are available
+        #   on both 6002 and 6004.
+        #
+        # - Exchange 2013 / 2016 / 2019 servers process RemoteName on their own
+        #   (via RpcProxyShim.dll), and the NetBIOS name format is supported only for
+        #   backward compatibility.
+        #
+        #   ! Default ACL is never used, so there is no way to connect to the endpoint mapper!
+        #
+        #   Allowed ports: 6001-6004
+        #
+        #   6001 is used for MS-OXCRPC
+        #   6002 is used for MS-OXABREF

+#
+#   Best way to learn how to use these calls is to grab the protocol standard
+#   so you understand what the call does, and then read the test case located
+#   at https://github.com/SecureAuthCorp/impacket/tree/master/tests/SMB_RPC
+#
+#   Some calls have helper functions, which makes it even easier to use.
+#   They are located at the end of this file. 
+#   Helper functions start with "h"<name of the call>.
+#   There are test cases for them too.
