How to stop internet access on 1 pc

jamoor · 7 Oct 2009 at 20:05

At work we have an SBS server linked to the internet via a sonicwall router.

Anyone know how I can stop 1 computer on the network accessing the internet (or anything bar 1 piece of software for that matter)

Surely you can block access through the router?

There is an option, but it seems to block everyone if I use it.

Have a fiddle it's more than likely possible. Otherwise, you could do the HOSTS file or use a free filter software.

whats the hosts file?

also any recommendations for a free filter?

You could configure the PC in question to use a none existant proxy
That way every connection it tries will go nowhere

I would have thought you could specify a special rule within the router itself.

If not...

1. Hosts File
2. Software firewall on the PC itself, just give the program you need to give net access an exception

what model SonicWALL is it?

OK, I changed the DNS servers to 111.111.111.111 that stopped the internet working easy enough.

Second problem - I need to completely lock down the PC as in only one piece of software will work via a shortcut on the desktop, is there an easy way of doing this?

If you're running a domain on the SBS network you're using don't forget DNS is important so I wouldnt recommend just turning it off on the machine!

Windows SteadyState.

Agreed. This could create a lot of issues.

OK, steadystate, good stuff.

Stopped the computer being part of the domain and made it a standalone machine on the network. (if that makes sense)

That sounds like good software (steady state).
