When you connect to a Windows Server 2003-based computer by using the Windows Server 2003 Remote Desktop Connection client, you can select the color resolution at which you want the client session to run. This functionality permits you to increase the resolution beyond the former limitation of 256 colors. However, by selecting this value, you are not guaranteed to connect at as high a resolution as you select, because the client setting is only one of the variables involved in generating a particular color resolution in the session.
Increase Color Resolution for Windows Server 2003-based Terminal ServicesWhen you connect to a Windows Server 2003-based computer by using the Remote Desktop Connection client, you can specify for the client to run with more than 256 colors. Before you specify a color-resolution setting, you must first set up Remote Desktop Connections. To do this, follow these steps:
- Right-click My Computer, click Properties, and then click the Remote tab.
- Click to select the Allow users to connect remotely to this computer check box, and then click OK.
- On another computer, start Remote Desktop Connections. To do this, click Start, point to All Programs, point to Accessories, point to Communications, and then click Remote Desktop Connection.
- Type the name of the computer that you are connecting to.
- Click Options to expand the connection window.
- Click the Display tab, and then select a color resolution other than 256 under Colors.
- Click Connect to start the session.
Set Group Policy for Maximum Color Depth of Terminal ServicesIn many cases, the client still connects with 256 colors instead of whatever value you specified in the Remote Desktop Connection box after you perform the procedure in the "Increase Color Resolution for Windows Server 2003-based Terminal Services" section of this article. This behavior may occur because of Group Policy on the Windows Server 2003-based computer that determines the maximum color depth that can be negotiated by the client. In Windows Server 2003, the default policy setting is 256 colors, but this setting can be changed by using the Group Policy Editor.
To use the Group Policy Editor to change the setting, follow these steps:
- Click Start, click Run, and then type MMC.
- On the File menu, click Add/Remove Snap-in, click Add, and then click Group Policy Object Editor.
- Click Add, make sure that Local Computer is selected in the Group Policy Object box, click Finish, click Close, and then click OK.
- Click Computer Configuration, click Administrative Templates, click Windows Components, and then click Terminal Services.
- Click Limit maximum color depth, and then select the color depth that you want.
NOTE: You cannot specify and connect at a higher resolution than your hardware can support. Therefore, if you have a video card in your computer that supports only up to 256 colors, you cannot connect to a session with a higher resolution than that.
