Consider the following scenario. You use the Remote Desktop Connection tool to connect to a Windows Server 2003-based terminal server. Additionally, a local disk is redirected to the terminal server in this terminal server session. However, when you try to copy a file from the redirected disk to the terminal server, the following Stop error occurs:If you use Debugging tools to analyze the crash dump file, you see that the system crashes at the rdpdr!RxLowIoCompletionTail point.

This issue occurs when certain antivirus software is installed on the terminal server. For example, this problem occurs when F-Secure Anti-Virus 8.00 for Windows Servers is installed on the terminal server.

This problem occurs because of a problem in the Terminal Server Device Redirector (RdpDr) driver.
