This directory contains code nearly identical to that found
in Ch7/SSNP. The only difference is that IMPRECV.CPP, which
replaces SSNPRECV.CPP, contains security code that allows any
account on any machine to connect to the pipe, and then impersonates
the client. Run IMPRECV on your machine. Run the sender on a 
different machine while logged in under a different account.
The two programs should connect and the receiver will start to
impersonate the client.
