This module will query the endpoint mapper and make a list
|
|
of all ncacn_tcp RPC services. It will then connect to each of
|
|
these services and use the management API to list all other
|
|
RPC services accessible on this port. Any RPC service found attached
|
|
to a TCP port, but not listed in the endpoint mapper, will be displayed
|
|
and analyzed to see whether anonymous access is permitted.
