If Microsoft Internet Explorer is configured to use a proxy auto-configuration (.pac) file, when you browse a secure Web site that contains multiple frames you may receive one of the following scripting error messages:
Message 1Message 2
This issue occurs because Internet Explorer does not correctly evaluate Internet security zones before it finishes processing the .pac file. When this occurs, Internet Explorer may assign a URL to an unexpected zone.
To work around this issue, add the Web site that is affected to the Trusted sites
security zone in Internet Explorer. To do this, follow these steps:
- Start Internet Explorer.
- On the Tools menu, click Internet
- On the Security tab, click Trusted
sites, and then click Sites.
- In the Add this Web site to the zone box,
type the URL of the Web site that is affected, and then click Add.
- Click OK.
You can also configure Internet Explorer settings by using Group
Policy. For more information about how to do this, visit the following
