3-InstallNamedInstanceSingleServerFromUncPathUsingSourceCredential.ps1

<#
    .DESCRIPTION
        This example shows how to install a named instance of SQL Server on a single server, from an UNC path.

    .NOTES
        Assumes the credentials assigned to SourceCredential have read permission on the share and on the UNC path.
        The media will be copied locally, using impersonation with the credentials provided in SourceCredential, so
        that the SYSTEM account can access the media locally.

        SQL Server setup is run using the SYSTEM account. Even if SetupCredential is provided
        it is not used to install SQL Server at this time (see issue #139).
