 Module Name:

    ExchangeServerSetup.cpp

 Abstract:

    This is a non-reusable patch for Exchange Server Setup 5.5 for SP2 and SP3
    to change the parameters passed to xcopy. The reason for that is that
    Win2k's xcopy doesn't have the /y parameter a default parameter.

 Notes:

    This is an app specific shim.
