Some of you might have noticed that you can’t update your virus definitions using the Norton Antivirus LiveUpdate feature after installing ISA Server. I ran into this one myself a few weeks ago. After a bit of head banging, I found a configuration that should work for everyone.
If you have problems getting Live Update to work, take a look at the follow procedures.
Scenario 1: Browser Configured as a Web Proxy Client
Perform the following steps if you are using the Web Proxy client configuration:
1. Click
Start and point to
Settings. Click on
Control Panel.
2. In the
Control Panel, click on
Symantec LiveUpdate.
3. In the
LiveUpdate Configuration dialog box, select the
Internet Options in the Control Panel option.
4. Click on the
Proxy tab. Select the
I want to use my Internet Explorer proxy settings option.
5. Click
Apply and then click
OK.
Scenario 2: Browser Not Configured as Web Proxy Client
In this scenario your machine is configure as either a SecureNAT or a Firewall client. When a SecureNAT or Firewall client sends a request to the ISA Server, the request can be handled by the Web Proxy service, or it can be sent directly to the Web server. How the request is dispatched depends on the configuration of the HTTP Redirector Filter. If you want to make life easy, you’ll configure the
HTTP Redirector filter to forward requests directly to the Web server.
Note that, while configuring the HTTP Redirector Filter to send the requests directly to the server will make life easier for you when it comes to dealing with LiveUpdate, it will ruin your ability to force everyone to use the Web Proxy service. The reason is that if you want to force everyone to use the Web Proxy client to access HTTP sites, you must configure the HTTP Redirector filter to drop requests from SecureNAT and Firewall clients.
1. Click
Start and point to
Settings. Click on
Control Panel.
2. In the
Control Panel, click on
Symantec LiveUpdate.
3. In the
LiveUpdate Configuration dialog box, select the
Internet Options in the Control Panel option.
4. Click on the
Proxy tab.
5. On the Proxy tab, select the
I don’t connect to the Internet through a proxy server option. You select this option because the SecureNAT and Firewall clients are not aware of the Proxy server, and you don’t want the LiveUpdate feature to be aware of it either.
6. Now go to the
ISA Server Management console at the ISA Server itself (I don’t trust the ISA MMC on remote computers; you can use Terminal Services though, if you want).
7. Expand your server name, then expand the
Extensions node. Click on the
Application Filters node. Double click on the
HTTP Redirector Filter entry in the right pane of the console.
8. In the
HTTP Redirector Filter Properties dialog box, click on the
Options tab.
9. On the
Options tab, select the
Send to requested Web server option. Click
Apply and then click
OK.
You don’t need to restart the server. Now go back to the SecureNAT or Firewall client on the internal network, and enjoy the LiveUpdate feature, now that it works again!
