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 :\Netmgmt.cab file, where   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:

Tsreg.exe

Tsreg.hlp

 Copy the Tsreg.exe and Tsreg.hlp files to a folder on the hard disk.</li> Double-click Tsreg.exe.</li></ol> </li> If the Windows 2000 Server Resource Kit is installed on the computer: <ol style="list-style-type: lower-alpha;"> Click Start, and then click Run.</li> Type tsreg in the Open box, and then click OK.</li></ol> </li></ul> </li> 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.</li></ol>

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.

back to the top

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.
