You need different IP settings for:
1. at home: 192.168.0.1, 255.255.255.0, no gateway
2. school: obtain everything automatically, Workgroup: School
3. at friends: 192.168.0.55, 255.255.255.0, gateway: 192.168.0.1, Workgroup: LAN, Computer Name: Nick
4. job: 10.10.1.40, 255.0.0.0, gateway: 10.10.1.1, Domain: youroffice.com (with username and password)

All settings are for one network card and so they have to be changed daily.

Manually: nerve-racking, with NetSetMan: only 2 clicks!

Profiles

The tabs symbolize the available profiles.
You can save 5 different settings in those tabs.

All changes are saved automatically so nothing gets lost by mistake.
"TEMP" does not save any filling-in. It is made for quickly changing the settings without using the complicated way through the windows network settings.

You can rename a profile by selecting it, right clicking it and choosing "Rename".

All available network connections are defined by their name and their type.

To edit one of those connections you have to load all available connection names into the combobox by pressing "Refresh" and finally choosing the right one.
If you copy the ini file to another computer the adaptername will be shown as "[?]" because the unique adapter id will not match on the other pc. You'll then have to reread the available connections.

To load the current IP or DNS settings from the chosen profile just click on the check mark.
Notice that the chosen profile must be connected for that.

Other settings like "PC Name" can be retrieved by double clicking on its caption.

To clear all settings of the current tab you have to first have to chose the tab, then right-click on its caption and "Clear Entries".
If you just want to clear a specific address you can do this easily by double-clicking on its caption.

There are some features that will help you to enter your values:
By clicking in an entry field its content will be selected so you can enter a new value right away.
If you enter 3 digits or press [tab], [ , ] or [ . ] on your keyboard the next address field is marked so you can continue typing in the address without losing any time or using your mouse.

You can click on the little star to fill in your favorite values.
To define favorite values you have to chose the tab, then right-click on its caption and "Save as Favorite".

To apply all settings of the current profile you have to click on "Activate".
Notice that only settings with a checked checkbox will be activated.
A new small window will pop up. It contains information about the current activation state.
There you can see which settings are applied at the moment and whether it was successful or not.
You can cancel the activation process by clicking the "Cancel"-button. Settings below the current point won't be set then.
Notice that even if you get an "OK" as a result it might be the best to reboot the pc or wait a while so changes can be synchronized in the network. (especially "PC Name" and "Workgroup/Domain")
If all results are green: good :-)
If not: Well, then you have to read the error message and try to solve the problem.
Here are the common errors and their meanings.

If you click on the "Info"-Button a small windows will pop up. There you will find some information about the program, links to the help file, relevant websites, etc.
Here you also can change the language or make NetSetMan start up automatically with Windows.
This will create a registry-key in "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run".

By minimizing NetSetMan it will appear in the tray bar (beside the clock).
There you can simply activate a profile. Just right-click the icon and choose the profile to set.
To avoid setting a wrong profile you have to activate the profile to be clickable in tray. To do this select the profile, right-click on the tab and click "Active in Tray". The small symbol besides the text shows that this profile will be clickable in tray. To deactivate it simply click "Active in Tray" again and it will disappear.

This message in the main window will appear at every 7th start of the program, on average. So this will be one time per week if you use it every day.
I'm sorry I have to do this but most of the users didn't pay attantion to the appeal not to use it at work. (whether they knew it or not).
This message is not included in the Pro verion, of course.

Click on the "C"-button to configure browser settings.
This works both with Internet Explorer and Firefox.
Your available Browsers will be shown in the browser field. Because Firefox supports several profiles every Firefox entry is shown with its profile name in brackets.
The rest should be self-explaining because it's quite similar to your browser.

If you haven't entered any browser settings you will see "(...)" in the main windows otherwise the chosen browser (IE = Internet Explorer, FF = Firefox) and the HTTP-proxy will be visible between "Browser" and the "C".

Please notice that Firefox must be closed before applying new settings.

To join a domain enter its name, your user name and your password. To enter your password click on the "P"-button. Now you can type in your password which will be saved encrypted in the ini-file. Neither you nor anybody else will be able to read it.

Usually it's enough to enter the pure user name.
If you get an error you can try entering one of the two following standards as your user name:
1. NETBIOS: DOMAIN\user
2. UPN: user@domain.com
Ask your administrator if you are not sure.
