Limitations to Terminal Services Farm Bookmarks from Virtual Office
Verify access and configuration is setup properly outside the remote access appliance first by connecting with
NetExtender then running your RDP client to connect as if you would were you inside your network. If
NetExtender is unable to connect properly there is likely another device or setting on the network that needs to
be configured properly.
Refer to your server's guide or contact Microsoft for additional help regarding Terminal Server settings if the
provided instructions do not work for you to change the settings.
• Interactive Login might need to be disabled. The windows login notice prevents the proxy from obtaining
the correct redirection server.
• Run gpedit.msc and go to Computer Configuration > Windows Settings > Local Policies > Security
Options and look for Interactive logon: Message title for users attempting to log on and Interactive
logon: Message text for users attempting to logon and ensure both are blank.
• Multiple RDP Sessions might need to be disabled. Multiple RDP sessions might cause more than one
redirection preventing the bookmark proxy from being able to connect to the correct server. Restricting
the user to on session in the Group policy prevents from occurring.
• Run gpedit.msc on the remote server and go to Computer Configuration > Administrative Templates >
Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections and
set the Restrict Remote Desktop Services user to a single Remote Desktop Services session to Enabled.
• Note that we create a new session request when connecting to the RDP server and are unable to clear
the old session through the bookmark. There might be some issues with your server setup depending on
your available licenses and how disconnected sessions are handled.
• Ensure SSO is correct if that option is enabled. Improper SSO credentials prevents the bookmark from
accessing the server properly. If you are running into issues, try disabling SSO and ensuring the proper
credentials are entered for connection.
• 'Force Java client usage' option for Java bookmarks is not recommended and is only available for legacy
support. There are no plans to further update the Java client.
• HTML5 RDP Client is recommended for usage for users connecting from systems unable to take advantage
of a native RDP client. Most modern browsers support the Web Sockets feature required for connection
and should be available on the systems that do not have a native RDP client.

• Select an Access Type Selection. Smart or Manual.
• Smart: Allows the firmware to decide which mode to launch on the client.
When creating a new unified bookmark, Smart is selected by default. Auto-detection is processed
using bookmark-specific default modes while launching the bookmark.
• Manual: Provides options to configure the modes, their priorities, and the choose method. At
least one mode should be enabled in the selection box.
The launch sequence is as follows: HTML5, and Java. Selecting Manual allows you to change,
enable, or disable the launch methods.
The up and down arrows are used to adjust the launch priority. Fork and tick are used to disable
or enable the modes. Disabled modes are put at the bottom of the list with a gray font color.
