The service settings page is divided into several fields. On top of the page is the weekday selection, than the interval and start time selection and finally the interval period. The settings you see om the screenshot above will scan the network each Sunday at 01:00:00.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NMap\Parameters\NMapArgsand
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NMap\Parameters\NMapServArgsNMapArgs contains all nmap related parameters and NMapServArgs all nmap service related parameters. NMapArgs contains per default: -sS -PI -PT, whereas NMapServArgs contains: 01:00:00 24 3 0 1 1 1 1 1 1 0 0 per default. See Registry Keys for more details on this keys.
Both parameters can be retrieved using the Get Param button of the NMapWin service page. Using
the Set Param button will store the current settings in the registry. The service can be
started/stopped using the two buttons Start and Stop.
The interval can be set using the slider or the corresponding text box. The PageUp,
PageDown as well as the Left and Right buttons are supported. PageUp and
PageDown will change the value in intervals max/5, whereas Left and Right are
changing the values with a stepsize of 1.
The NMapServArgs syntax is:

Select the weekdays you want to scan your network by selecting the corresponding checkboxes
on top of the service settings page. In case the selected interval (see
interval setting is more than one day, the nmap
process will only start on days which are selected here. For example, if you select every
second day for scanning, and the next scan day is not selected in the weekday selection, this
day is skipped and the next scan will be performed 2 days later (assuming that this is selected
in the weekday selection).
Interval selection
The scan interval (the period of time between two consecutive scans) is determined by the interval
factor and the interval period. The interval factor can be Hours, Days, Weeks
or Month. Depending on the selected factor the interval slider is changing the minumum
and maximum scale. In case you select Days as interval factor the slider min, max values
will be 0 to 30 (one month).Start date/time
The start date/time can be selected using the two tect boxes in the middle of the tab. The date
field will open a calendar in which one can select the start date for the first scan. The time is
selected using the up and down buttons, or by editing the box directly.Options
After installation the AutoStart is set to 'OFF'. Therefore the service will not start any
scan job until the AutoStart flag is set to 'ON'. The change is propagated to the service
immediately. Nevertheless, depending on the Immediately flag setting, the start of the next
scan job could be delayed until the next scan time.
Registry keys
The registry keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NMap\Parameters\NMapArgs
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NMap\Parameters\NMapServArgs
are used to store the current setting of the NMap service. The syntax of the NMapArgs key
is exactly identical to the nmap command line arguments. See the NMap
manual page for more information on the different command line arguments.
In case the registry keys are changed using a registry editor, the new values will be automatically
before the next scan starts.
