SUMMARY
WARNING: If you use Registry Editor incorrectly, you may cause serious
problems that may require you to reinstall your operating system. Microsoft
cannot guarantee that you can solve problems that result from using Registry
Editor incorrectly. Use Registry Editor at your own
risk.
This step-by-step article describes how to use
the Terminal Services Client Registry Editor tool (Tsreg.exe) to modify
Terminal Services client registry settings in Microsoft Windows 2000 Terminal
Services.
Tsreg.exe is available in the
Microsoft Windows 2000 Server Resource Kit. You can use this graphical user interface-based tool to modify
registry settings that relate to Terminal Services client options such as
bitmap and glyph caching.

To start Terminal Services Client Registry Editor:
- Install the Windows Terminal Services client if it is not
already installed on the computer.
NOTE: To use Tsreg.exe, the Terminal Services client must be installed
on the computer. - Use the appropriate method:
- If the Windows 2000 Server Resource Kit is not installed on the computer:
- Insert the Windows 2000 Server Resource Kit CD-ROM
into the CD-ROM or DVD-ROM drive.
- Locate the drive
letter:\Netmgmt.cab file, where drive
is the CD-ROM or DVD-ROM drive that contains the Windows 2000 Server Resource
Kit CD-ROM, and then locate the following two files:
- Copy the Tsreg.exe and Tsreg.hlp files to a folder
on the hard disk.
- Double-click Tsreg.exe.
- If the Windows 2000 Server Resource Kit is installed on the computer:
- Click Start, and then click Run.
- Type tsreg in the Open box, and then click OK.
- Terminal Services Client Registry Editor uses the following
4 tabs:
Bitmap Cache
Glyph Cache
Miscellaneous
Client Profiles
Click the tab that corresponds to the type of
settings that you want to configure. The settings that are contained in each
tab are described in more detail in the following sections of this article.

The Bitmap Cache Tab
Bitmap caching stores frequently-used bitmaps (for example, the
bitmap that is used to display the
Start button) in a file on the client computer. This improves
performance by minimizing the amount of information that is transferred over
the network connection.
Bitmap caching is turned on a per-session
basis from the client and requires 10 megabytes (MB) of free hard-disk space on
the client computer.
The client uses persistent bitmap caching to
store bitmaps that are sent from the server on persistent media such as a hard
disk. Upon connection, the client informs the server of the bitmaps it has so
that the server does not have to resend them.
The bitmap cache values
that you configure on the
Bitmap Cache tab are set in the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client
To modify bitmap cache settings, run Tsreg.exe,
click the
Bitmap Cache tab, and then configure the settings.

The Glyph Cache Tab
A glyph is made up of a character (such as a letter or number)
and the font information that is required to calculate how the character is
displayed. The glyph cache is stored on the client computer and contains
outline, vector, or raster font information that is used to display characters
on the client.
The first time that a glyph is requested, its
appearance is calculated, and then stored in the glyph cache. The next time
that the glyph is needed, it is transferred from the cache to the screen or
page buffer.
The Glyph cache values that you configure on the
Glyph Cache tab are set in the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client
To modify glyph cache settings, run Tsreg.exe, click
the
Glyph Cache tab, and then configure the settings.

The Miscellaneous Tab
Use the
Miscellaneous tab to turn on or turn off the use of a shadow bitmap or
dedicated terminal, configure the order draw threshold, and set the foreground
lock timeout value.
The values that you configure on the
Miscellaneous tab are set in the following registry keys:
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client
-and-
HKEY_CURRENT_USER\Control Panel\Desktop
To modify these settings, run Tsreg.exe, click the
Miscellaneous tab, and then configure the settings.
back to the top
The Client Profiles Tab
You can save the settings that you configure on the
Bitmap Cache,
Glyph Cache, and
Miscellaneous tabs in a custom profile. Profiles are useful when the client
uses different combinations of configuration settings. Use the
Client Profiles tab to save, load, or delete custom profiles.
Profiles
are saved to the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client
To save, load or delete a client profile, run
Tsreg.exe, click the
Client Profiles tab, and then make the changes that you want to use.
