Microsoft reports vulnerability

REDMOND, Wash., July 19 (UPI) -- Washington's Microsoft Corp. is warning its Windows 2000, Windows XP and Windows Server 2003 are vulnerable to denial-of-service attacks.

The problem lies in the Remote Desktop Protocol, which enables remote access to Windows systems, TechTree.com reported.

Microsoft, which is working on a patch, suggests users block TCP port 3389 on their firewalls, disable Terminal Services or Remote Desktop if not required, or secure remote desktop connections using either Internet Protocol Security or a virtual private network connection until a patch is ready.

There have not been any reported attacks seeking to exploit this vulnerability, the company said.
