I attempted to change the settings while logged into the server and the settings changed there were not reflected on the workstation.
I agree with others that this seems to be a user level setting, so this needs to be done on all machines the user will use.
This is what worked for me:
1. run \\{servername}\lansweeper$\lsremote.exe
2. click on the options button
3. change the options to the settings you want as default
4. click on the options button to close the options section
5. close lsremote(click on x in top right corner)
If I closed lsremote without clicking on the options button a second time, it would not save my settings.
