Additionally, the following error and information messages may be logged in the Application event log on the server side:
This issue occurs when a font package that is not valid is installed on the Windows Server 2003-based server that is running Terminal Server. When you try to log on, the font package that is not valid causes data structure corruption that finally cannot be handled by the Winlogon service. Therefore, a Terminal Server connection session cannot be established.

To work around this issue, rename a registry key so that the Winlogon service does not use these fonts during Terminal Server client connection initialization. To do this, follow these steps:
Click Start, click Run, type regedit, and then click OK.
Note All Type 1 fonts will be disabled after you rename the Type 1 Fonts registry entry. After the logon process is complete, you can change the entry back to the original name, and the Type 1 fonts will again be available. If you still experience the problem, contact the font manufacturer of the Type 1 fonts to replace this font package.
