using bat to block websites?

[Kim K]

Is it possible for me to include in a logon.bat websites that I want to block
access to? If so can someone please send me a script on how I would do this
so I can include this in my logon? I want to block access for students to
use free email accounts in the classroom.

Get yourself a proxy server. Squid is worth a look (free) - or
Microsoft's ISA Server, if you're into Active Directory integration. If
you *really* want to block access to certain websites and it is relevant
for your business workflows or whatever, you should not think about a
batch script that does this (if there even is such a thing). You should
think about a central solution like a proxy where all access to the
internet/other networks is handled instead of touching or messing around
with each client.

Just my 2 cents

cheers,

Florian

I agree with Florian's comments. However, strictly answering your
question, this may get you started:
ECHO 127.0.0.1 youtube.com >>%SystemRoot%\system32\drivers\etc\hosts

Note that the location of "hosts" is not fixed but specified in the
registry(1) - it could be somewhere else it's very easy for a
determined user to defeat this method.

1) HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath
