Routine Description:
This routine is the exported API to analyze a system and save mismatched/ unknown information to the SAP profile. If any error occurs when loading SMP information into memory, this routine will stop, free memmory, and return the error code. If a error occurs when analyze an area, it will stop analyze. All successful and fail transactions will be logged to the logfile(or stdout).
All analysis information is saved to a SAP profile with a date/time stamp.
All old analysis information is cleared before new SAP information is saved.
Arguments:
InfFileName - The file name of a SCP used to compare the analysis of a system
DatabaseName - The JET analysis database name. If NULL, default is used.
AnalyzeOptions - options to analyze
bAdminLogon - if the current calling thread is in administrator's logon
Area - One or more areas to configure. AREA_SECURITY_POLICY AREA_USER_SETTINGS AREA_GROUP_MEMBERSHIP AREA_REGISTRY_SECURITY AREA_SYSTEM_SERVICE AREA_FILE_SECURITY
pdWarning - the warning level

Routine Description:
This routine analyzies the system security in the area of system access which includes account policy, rename admin/guest accounts, and some registry values.
Arguments:
pSmpInfo - The buffer which contains SMP information to compare with If dwSaveOption is set to non zero, the difference is saved in this buffer to output
pScpInfo - If dwSaveOption is set to non zero, pScpInfo may be present to be used (as effective policy) to compare with
dwSaveOption - used by policy filter when to query policy difference SCEPOL_SYSTEM_SETTINGS - query for system setting mode SCEPOL_SAVE_DB - policy filter for local database SCEPOL_SAVE_BUFFER - policy filter for GPO mode (DC) 0 - analyze mode
pbChanged - TRUE if there is any policy changed
