DRAGON DESKTOP SOLUTIONS
Overview
• Introduced with Dragon Medical 10.1, this support is new in DNS12 -and only in Professional and Legal.
• Enables the use of DNS from a computer on which DNS is not
installed.
– Windows clients connect to a supported server using Microsoft’s free
Remote Desktop Client software.
– Uses Windows Remote Desktop Services, which offers a bi-directional
audio only in Windows Server 2008 R2 and Windows 7 Ultimate
– Application support for DNS on the server is identical to local DNS
installations
• Single installation of DNS Pro/Legal on a server can allow multiple,
concurrent Windows client connections

Benefits of the Feature
• On Windows Server 2008, a single DNS installation allows
concurrent connections for multiple end-users (limited by server
capacity and network bandwidth)
• Financial and administrative benefits:
– One installation on the server reduces administrative overhead for client
installation and maintenance
– Eliminates the need to install and support expensive Citrix client and
server software, and the Dragon extensions needed to support Citrix.
– Capacity and quality of audio support is expected to equal Citrix.
• An alternative for thin clients (PCs that do not meet DNS's minimum
system requirements)

Using DNS over the Connection:
About DNS Profiles
• Preparing to use DNS:
– On the local PC, connect the microphone and run the ASW.
– This ensures audio quality is acceptable. It’s NOT part of profile creation
because the microphone and ASW software are on your local machine, not the
server.
– Connect to the server, start DNS and create a profile or open an existing
one.
– If creating a new profile, you must perform General Training. Other steps are the
same as when you create a profile locally.
• NOTES:
– If you already have a V12 profile on a different machine, you can copy or
import it to the server so it can be accessed in DNS there. For these
profiles, we strongly recommend you perform ASW locally before using
DNS in the new environment.
– The Roaming feature is supported for use with RDC.

Using Dragon with RDC:
Dictating and Using Other Features
• All Professional/Legal features are available for RDC client
connections.
• Full Text Control is available for the same applications as local DNS,
as long as the applications are installed on the same server where
DNS is installed.
• Recommendation: advise users to save their documents often, in
case connectivity is lost, audio quality is degraded by low availability
of network bandwidth, etc.

Limitations
• As mentioned, the number of concurrent users is determined by a
number of factors, including server disk space capacity and network
bandwidth.
• Installation on a single server requires product activation to occur
once. Thereafter, Nuance/DNS has no technical means to count or
limit the number of users that can access and use a single serverbased installation of DNS.
• As for Citrix, site administrators are responsible for configuring and
troubleshooting server-based issues, including WTS, that may affect
the use of DNS.

Troubleshooting
•
On the server:
– Check "Remote Audio" device is
created on the server after running
the RDC session (in Control Panel,
under Sound settings-->Recording)
– Verify that the value is 0 for
"fDisableAudioCapture" under the
registry
HKLM\SYSTEM\CurrentControlSet\
Control\Terminal
Server\WinStations\RDP-Tcp
•
16
On the client: verify the “Record
from this computer" option is
enabled in Remote Desktop
Connection
