SYMPTOMS
When you attempt to join an online conference, you may receive the following error message:

An ActiveX control on this page is not safe.

Your current security settings prohibit running unsafe controls on this page. As a result, this page may not display as intended.

After you clear the error message dialog box, you receive the following Web page error messages:

An audio/video connection to the Exchange Conferencing Server could not be automatically established. Verify that your browser security settings permit the download of ActiveX controls.

Data Conferencing Frame

Join Instructions

The Conferencing Server can not automatically join you to this conference. You will need to manually connect your conferencing client, such as Microsoft NetMeeting.

Please try the following:
 * Conferencing Server: Server Name
 * Conference ID: 00000
 * Password: password

where:
 * Server Name is the name of your conferencing server
 * 00000 is a randomly generated numeric number

and
 * password is the conference password



CAUSE
This problem occurs because the security setting in Microsoft Internet Explorer is either set too high or because you altered certain custom settings.



RESOLUTION
In order to participate in an online conference, make sure that the following settings are enabled and configured in your browser as shown below in the &quot;More Information&quot; section of this article.



STATUS

To Modify Security Settings in Internet Explorer
 On the Security tab, set the Security level for this zone slider to Medium.

or If the security level slider is set to High, or you set a custom setting (by clicking the Custom Level button on the Security tab), modify the appropriate zone with the following settings:  In the Security Settings dialog box, under ActiveX controls and plug-ins, set the following:

under Run ActiveX controls and plug-ins, click Enable.

 In the Security Settings dialog box, under Cookies, set the following:

under Allow per-session cookies (not stored), click Enable, or Prompt.

</ul> </li></ul>
