Many RPC problems are caused by slow links. RPC connectivity can be confirmed by
RPCping.exe. See Q167260.
Remote access using Netview, Regedt32, User Manager for Domains and Server
Manager for Domains use RPC communications. For troubleshooting tips beyond
connecting with the above RPC-based tools, see Q177446
The remote procedure call (RPC) Ping tool may not work when the Run with
Security option is selected.
The RPC tools package contains three separate tools for
obtaining information from a system that is running RPC services. rpcdump allows
you to dump the contents of the endpoint mapper database. ifids is similar to
rpcdump but allows you to query a single RPC server and can even allow you to
query an RPC server which is not listed in the endpoint map obtained with
rpcdump above. walksam is a tool which allows you to dump the information of
each user found within the SAM database via Named Pipes or using the additional
protocol sequences used by Windows 2000 domain controllers. rpcdump, ifids, and
walksam are demostration programs from the Null Session and MSRPC concepts
discussed at BlackHat Windows 2000.
