You can create a customized installation of Internet Explorer 9 using the Internet Explorer Administration Kit 9
and then deploy that install across the network. To allow users to install the custom package from a network server, you should specify your network servers as trusted sites. To do this:
- In Internet Explorer, click Tools, and then click Internet Options.
- Click the Security tab, click Local intranet, and then click Sites.
- Clear the Include all network paths (UNC) check box, and then click OK.
- Select the Trusted sites zone, click Sites, type the path for the download server, and then click Add.
Do this to add each download server you want to be trusted.
