Managing ActiveX
®
controls
The DSView 3 software uses ActiveX controls to provide interactive content for viewers. (The
Avocent Telnet Viewer uses Java; see
Java Installation on page 46 for information.)
The functionality of the ActiveX controls is determined by the settings for the security zone being
used by the DSView 3 software. See
Security zones on page 24.
Administrators may prevent users from installing software on their computers. In this case, the
Windows domain administrators may choose to “push” an MSI installer using a Group Policy. This
will silently install the Avocent Session Viewers without requiring the user to install the software
themselves. This will install only the viewers for Internet Explorer. The MSI file is located on the
DSView 3 software CD and in the webapp/applets directory on the DSView 3 software server.
Use the following procedures if you are permitted to install software.
To download an ActiveX control on a DSView 3 software hub server using
Windows (all operating systems except Windows XP with Service Pack 2):
1. In a Units View window that contains target devices (see Accessing Units View windows on
page 88), click the link in the Action field or select an alternate action, if available.
You can also access a Unit Overview window for a target device and click the icon or link for
the session type.
If this is the first time the ActiveX control has been requested by the DSView 3 software, an
Avocent Session Viewer message box will appear, followed by a Security Warning dialog box.
2. Select Always trust content from Avocent Huntsville Corporation .
3. Click Yes to download the ActiveX control. When the control has been downloaded, a KVM
session will start in a Video Viewer window or a serial session will start in a Telnet Viewer
window, depending on the supported action for the managed appliance.
If the required ActiveX control could not be loaded, a red X will appear in the Avocent Session
Viewer message box. The ActiveX control may fail to load for one of the following reasons:
• The user did not select Always trust content from Avocent Huntsville Corporation.
• The DSView 3 software client security zone settings are not correct.
• The ActiveX control failed to properly install.
To download an ActiveX control on a DSView 3 software hub server using
Windows XP with Service Pack 2:
1. In a Units View window that contains target devices (see Accessing Units View windows on
page 88), click the link in the Action field or select an alternate action, if available.
You can also access a Unit Overview window for a target device and click the icon or link for
the session type (see
Unit Overview Windows on page 94).
If this is the first time the ActiveX control has been requested by the DSView 3 software, an
Avocent Session Viewer message box will appear.
