SYMPTOMS
Consider the following scenario:
 * You use the Remote Desktop utility (Mstsc.exe) on a Microsoft Windows XP-based client computer to connect to a Microsoft Windows Server 2003-based host computer.
 * On the Local Resources tab of the Remote Desktop Connection dialog box, you select Serial ports under Connect automatically to these local devices when logged on to the remote computer.

In this scenario, the client computer may leak memory when the serial port receives data.

<div class="cause_section">

CAUSE
This problem occurs when the Remote Desktop utility is configured to connect serial port devices to the host computer. In this configuration, the host computer assumes that the serial port devices are connected to a local serial port on the host computer.
