I use the same laptop from home for work. When my adult children are suppose to help me at work, they are instead checking their emails, social sites, etc. How can I block all of that while on my work network but have it maintain unlimited access at home without changing the settings everyday? In other words, I would like all of us to not be distracted while at our work location.
Do you have access to work router settings? Some routers have parental controls built in and you can utilize it to block everyone at work from using selected webpages. If you must have control on your laptop you may want to look into dynamically loading hosts file but I'm not sure if it is possible.
There are software packages you can run on the laptop itself which will prevent the laptop from visiting certain websites or categories of websites. However...
The ideal solution would be to persuade the administrators of your network at work to install some type of content filtering software on the network box itself, and to make sure that your kids don't know the password to the router. That should at least provide some degree of protection, because a router sitting behind a complex password is much more secure from tampering than a Windows laptop, even if you only give your kids a Standard User account and require admin access to modify the content filter.
Lastly, keep in mind that any content filtering solution is probably going to be "dumb" by default and always keep the filtering enabled unless you explicitly disable it, and vice versa; so you'll have to enable it at the start of your work day and disable it when you get home. This can be repetitive and annoying and I don't know of any products that can automate this effort depending on the network you're connected to -- although I'm sure that would be a very welcome feature that some company may be working on or has already deployed....
I am not going to recommend any specific products by choice, because that'd be a product recommendation, and those aren't allowed here. You can use Google to find a good software product if that is your choice, however.
