Restrict IE content for specific accounts

I would like to restrict for several (that are not admnistrative) accounts of my PC the ability to access Internet sites with IE other than the ones I will specify. I tried logging to those accounts but IE says that I can only do this from an administrative account.

I looked at Windows® XP Security Console (as suggested at http://www.experts-exchange.com/OS/Miscellaneous/Q_21680248.html) but when I run it I cannot see anything that will allow me to limit those settings.

No you cannot really do this with IE. The only real solutions is to use a proxy server, which is probably a bit overkill, or use a third party product like Net Nanny. http://www.netnanny.com/

Well, there is a way you can do this...  It would involve the HOST file, where you can place the specific internet sites you wish to allow, with their 'friendly' Names and IPAddresses, a .bat file that reconfigures the TCP Properties NOT to use a DNS server address (which executes upon user logon), and of course a .bat file that executes upon Admin logon that DOES include the GOOD DNS address...

You would use Netsh commands to create your batch files...

First, create a folder called c:\configs, configure TCP for normal use and run this command:

netsh -c interface dump > c:\configs\GoodDNS.txt

Then configure TCP for a BAD DNS server as in 0.0.0.0 and run this command:

netsh -c interface dump > c:\configs\BadDNS.txt

Create 2 .bat files:

netsh -f c:\configs\GoodDNS.txt
and
netsh -f c:\configs\BadDNS.txt

Place the BadDNS bat file in the UsersStartupFolder, and GoodDNS in the Admin StartupFolder..

In the Hosts file, you can place the specific sites you with to allow...

Now, this is not full proof, as anyone with some advanced knowledge can do an NSLookup on an external DNS name with a good DNS server and find the IPAddress of a site, and just place the IPAddress into the Address Bar to get to an outside site, but the normal user would not likely think of this...

I didn't check netnanny as I wasn't looking for a solution of 40$ per PC. I just thought of maybe a windows registry solution. But netnanny (I asked today their support service) should work. Fatal exception's solution instead is not completely safe, so I wouldn't consider it as a viable one.

Why you never posted that you still need help and this is not helping?
Noone is a mindreader and noone will post you new suggestions if you  ignore the old ones. :)

I didn-t post as I took for granted KCTS's comment "No you cannot really do this with IE".

As for Fatal"s, I said it is not safe as you said that it is not full prrof. So, it is not safe for the lab.

Note..  Nothing is fullproof, ever!  But there are levels of safety..  the one I suggested has a high level of safety, as only those users that understand DNS could circumvent it,..  Tell you what..  ask a basic user what DNS does and how it works and I think you will just find a vacant face stare back at you..  They have no idea that you can use an IPAddress to get to a website..  JMHO though...

I didn't even try to apply your suggestion as you said that it was not full proof. But I'm going to leave Venabili decide about it. Anyway, I appreciated you spending your time to try to help me.
