In the Remote Audio drop-down list, select Play on this computer, Play on remote
computer, or Do not play.
If the client application will be RDP 6 (Java), you can select any of the following options
as well: Dual monitors, Font smoothing, Desktop composition, or Remote
Application.
Remote Application monitors server and client connection activity; to use it, you need
to register remote applications in the Windows 2008 RemoteApp list. If Remote
Application is selected, the Java Console will display messages regarding connectivity
with the Terminal Server.
Optionally select Automatically log in and select Use SSL-VPN account credentials
–
to forward credentials from the current SRA session for login to the RDP server. Select
Use custom credentials to enter a custom username, password, and domain for this
bookmark. For more information about custom credentials, see
with Custom SSO Credentials" section on page
In the Encoding drop-down list, select one of:
–
Raw – Pixel data is sent in left-to-right scanline order, and only rectangles with changes
–
are sent after the original full screen has been transmitted.
RRE – Rise-and-Run-length-Encoding uses a sequence of identical pixels that are
–
compressed to a single value and repeat count. This is an efficient encoding for large
blocks of constant color.
CoRRE – A variation of RRE, using a maximum of 255x255 pixel rectangles, allowing
–
for single-byte values to be used. More efficient than RRE except where very large
regions are the same color.
Hextile – Rectangles are split up in to 16x16 tiles of raw or RRE data and sent in a
–
predetermined order. Best used in high-speed network environments such as within the
LAN.
Zlib – Simple encoding using the zlib library to compress raw pixel data, costing a lot of
–
CPU time. Supported for compatibility with VNC servers that might not understand Tight
encoding which is more efficient than Zlib in nearly all real-life situations.
Tight – The default and the best encoding to use with VNC over the Internet or other
–
low-bandwidth network environments. Uses zlib library to compress pre-processed
pixel data to maximize compression ratios and minimize CPU usage.
In the Compression Level drop-down list, select the level of compression as Default
–
or from 1 to 9 where 1 is the lowest compression and 9 is highly compressed.
The JPEG Image Quality option is not editable and is set at 6.
–
In the Cursor Shape Updates drop-down list, select Enable, Ignore, or Disable. The
–
default is Ignore.
Select Use CopyRect to gain efficiency when moving items on the screen.
–
Select Restricted Colors (256 Colors) for more efficiency with slightly less depth of
–
color.
Select Reverse Mouse Buttons 2 and 3, to switch the right-click and left-click buttons.
–
Select View Only if the user will not be making any changes on the remote system.
–
Select Share Desktop to allow multiple users to view and use the same VNC desktop.
