SYMPTOMS

In Microsoft Windows XP, when you try to connect to a network resource, the connection may time out. Additionally, you receive an error message that resembles the following:
Windows cannot find the network path. Verify that the network path is correct and the destination computer is not busy or turned off. If Windows still cannot find the network path, contact your network administrator.
For example, this problem may occur when you try to connect to a shared resource by using the server message block (SMB) protocol.

CAUSE

This problem occurs because the redirector processes a corrupted record repeatedly.
