        NTNWtoUNCFormat

Routine Description:

        Given a connection handle and a path, change it to UNC format
        if it's in NetWare format.  I.E.

        SYS:\usr\terryt   ==>   \\HELIUM\SYS\usr\terryt

        Don't do the conversion if it's not in NetWare format.

Arguments:

        ConnectionHandle   -  Connection Handle
        NetWarePath        -  Input original path

Return Value:
        UNC string
