I have a Windows NT 4.0 Server Network and clients are running NT 4.0 workstation and some are still running windows 98 how would I restrict access at the user level to prevent certain users from accessing the internet but still want them to have network access? Please email me at wroming@ci.killeen.tx.us thank you for your help and I look forward to your anwsers.

On Windows NT, deny them permissions to iexplore.exe and netscape.exe and that should keep them from running the browsers to surf.

On Windows 98, you'll probably need third-party software such as Fortres101 (http://www.fortres.com) to lock down the browsers.

Good luck!

Take care,
Mike

That would only work on there machine is there a way to do it for the login name because just dening them access on the machine yes we have done but it does not stop them from going to another computer to use the internet. How would you do it then Ihave already checked for possible policies to implement but none prevent interent access in 4.0 if we had 2000 they would but not 4.0 any other suggestions?

Are you running a Firewall of any type?
If not, how are you protecting your network from the outside world?
Are you using a hardware or software firewall?
If you are using a firewall, there should be some sort of authentication for it. Denythe user's access from there.
We use Checkpoint's Firewall-1, and have had no problems with it, but I know there are other companies out there that also make firewall software.

Good Luck,

But with Checkpoint you can only do it by machine we have users that move through out the city so that would not work. That was the first thing I thought of. WE are using the same firewall software. Unless there is somthing that I missed in Checkpoint there is not a way to restrict a user that works from more than one machine without restricting the whole machine. Or is there?

**************UPDATE************************* I am going to need the fix to be able to do it from the user login not just on the single machine but when the user moves to another machine I need it to be like a roaming profile or policy. How would you do that in NT 4.0 I know how in 2000 but we are a 4.0 shop at the present time.

Checkpoint's client is installed on each PC. It then will start with logon, but it will ask for a separate login to be able to access the internet. If no login is supplied, it will not let the user access anything on the internet.

Are you using Proxy server for internet access? What are using to allow the users internet activity? If you are using Proxy server 2.0, there are many ways of restricting access using the Winsock Proxy client.

We are using Checkpoint Firewall and the way to do it at user level access is not premitted to implement at our workplace.
