Error: 'RPC Server is unavailable'

Question:

The client machine displays error "RPC Server is
unavailable".

Answer:

The error is usually caused because the server can't be 

located.  Make sure you can ping the server machine using

the string you typed into the ComputerName property of the 

TRemoteServer.   You might also want to try using an IP

address instead in case there is some problem with your DNS 

configuration or the hosts file.  Try setting the "Default 

Authentication Level" to <none> (Run DCOMCNFG on the

server to do this.)  Lastly, check the Microsoft

Developer's Network on the Web for the latest information

on this Microsoft transport.  The MSDN can be located 

at the time of the writing at www.microsoft.com/msdn.
