Hello, we have a user who is experiencing an issue when attempting to establish a VPN connection between their notebook computer and our PIX 506e. Upon successfully establishing a VPN connection, the user's notebook will crash at random times while connected (anywhere between 1 minute and 3 hours). The crash results in a blue screen error (Windows generated) and a restart- it is not recoverable.
The user's computer is a new Dell notebook running Windows XP Professional edition. This issue has occurred at multiple locations for this user including locations with DSL and T1 connections. Windows is fully patched, and this issue occurs both when the notebook is connected to the network wirelessly or hard-wired. The VPN Client CD that came with our router includes versions 4.6 and 4.0.5 of the Cisco VPN Client software. We initially installed 4.6 on the notebook, but have since uninstalled 4.6 and installed 4.0.5, but the issue still occurs. I have instructed the user to not establish a VPN connection until a solution has been discovered for this issue, as I am concerned about data loss and damage to the computer.
The procedure described in this document requires modifications to the Microsoft Windows registry. Please use extreme caution when modifying the registry. This only applies to Install Shield based installations. It does not apply to installations performed by the Microsoft Windows Installer (MSI) available for Windows NT, Windows 2000, and Windows XP.
Ok, so it looks like the link you provided describes how to manually uninstall the Cisco VPN Client 3.5 and later for Windows 2000. After uninstalling the VPN Client, is there another version of the Client software that you reccomend? Also, are these instruction compatable with Windows XP (Professional Edition) macines?
