VPN Client Restart Windows XP

Unanswered Question
Oct 4th, 2010

Hi to all people,

I have installed the last Cisco VPN Client, for this OS., v5.0.07.0290 for 32 bits. When I trying to establish a connection to a Cisco VPN Server, the client connect correctly, but then, Windows XP restart without any info or error message. I looked the Event Viewer and there isn't any error log or crash.

Do you have any idea of what's happening? Any software in conflict?

I have a Comodo Personal Firewall and Avast Personal installed and running.

If you need some additional info, request it to me

There can be some things with which cisco vpn client is not compatible with. You can check the following:-

[1]VPN Client supports smart card authentication on Windows 7, Vista, and XP.

[2]VPN Client supports up to one Ethernet adapter and one PPP adapter.

[3]VPN Client 5.0.x is incompatible with the combination of Cisco Unified Video Advantage 2.1.2 and McAfee HIPS Patch 4 Build 688.

To avoid system failures, uninstall either of these two applications,upgrade McAfee to the latest version, or use VPN Client 4.6.x.

[4]The VPN Client is not compatible with Microsoft ICS (Internet Connection Sharing (ICS) on the same PC.

You can read more about this in the following link:-

Also please try to disable the firewalls present on the PC and see if it helps.

I hope this helps.

Hi ,

It looks like that the Windows XP machine is restarting as soon as the VPN Client connects to the VPN Server. Do you get time to pass traffic through the VPN before the system restarts or is it instantaneous ? Do you get a Blue Screen on Windows ?



guijarrelson Mon, 10/04/2010 - 02:25

I don't have any message error in the system, blue screen or any message box. I connected it, and then, instantaneous restart.

I have other Windows XP running with the client connecting to the same VPN server, but in this host, it restart it.

Please try disabling the firewall and antivirus and check if that helps. Do the other PCs have the same Anti Virus and Firewall installed ?

if disbaling firewall antivirus does not help, try uninstalling it

disbale firewall and anti virus

reinstall again

vpn client does not have too many issues with win xp sp this kind of bothers me

guijarrelson Mon, 10/04/2010 - 04:50

This host, doesn't have the same antivirus and firewall. The host that works, have a Symantec Endpoint Protection.

This night I'll try to uninstalling it, and reinstall the VPN Client.

Well, another thing, when I tried to uninstalling it, Windows restart too. The only way to clean up it, is doing a system restore. Could you give me the paths of the installation software to make a clean install?

Thanks in advice

Namit Agarwal Mon, 10/04/2010 - 04:54


I would recommend that before you uninstall and install VPN Client, please test after removing Avast and the Personal Firewall. Avast can sometimes cause issues with the VPN Client.



Jitendriya Athavale Mon, 10/04/2010 - 04:57

go to the add/remove program and remove it from there

again this is really wierd that it doesnt even let you un install,

disbale firewall and anit virus even while you uninstall

i think the anti virus is the one breaking things here, my doubts are increasing bcoz other hosts in your network do not have the same fw anti virus

guijarrelson Mon, 10/04/2010 - 05:03

I think that Antivirus is not the problem, because I have another host with Windows 7 and the same Firewall and Antivirus, and work fine.

The problematic host, resides in other site, other network than the other XP, but in the same as the other Windows 7. In Windows 7, with Avast and Comodo Firewall runs ok, in XP nook.

Please send me the output of the following file vpnclient.ini. Its located at the following path C:\Program Files\Cisco Systems\VPN Client\



guijarrelson Mon, 10/04/2010 - 15:09

This is the output of vpnclient.ini:

DefaultConnectionEntry=AE Desarrollo

And I get the Windows Core Dumps Files after the restart when I trying to connect.

This try, I did without Firewalls and without Antivirus running.

Namit Agarwal Mon, 10/04/2010 - 18:45


Please change the value of keyword StatefulFirewall=1 to StatefulFirewall=0 and save the file. Restart the VPN Client . Check if this helps



guijarrelson Mon, 10/04/2010 - 23:27

Ok, I'll try later with the option. What's the function of this option?


Namit Agarwal Mon, 10/04/2010 - 23:34


This option will disable the stateful firewall on the VPN Client. Sometimes the VPN Client firewall can create incompatibility issues with the local PC Firewall and Anti Virus



guijarrelson Mon, 10/04/2010 - 23:37

Ok, I'll test it this evening.


Do you need any extra information?

guijarrelson Tue, 10/05/2010 - 16:14

Disabling the Stateful Firewall option, I have the same result. Windows restarting.

Any idea?

guijarrelson Wed, 10/06/2010 - 00:55

Yeah, I try a clean install. VPN has any extra path different as C:\Program Files\Cisco Systems\VPN Client\, to perform the most clean install than I can?

No error log in the Event Viewer.

Namit Agarwal Thu, 10/07/2010 - 10:22

Hi ,

Do you the installation file with you ? Can you paste the name of the file , is it vpnclient-win-msi- ? Just want to confirm that we are not installing the 64 bit version of this client which has the installation file vpnclient-winx64-msi-



guijarrelson Thu, 10/07/2010 - 14:31

I confirm that the software is the 32-bits version. I can't tell you if that was the name, because the name was changed. Could you provide me an alternative download for the client? I requested to my sysadmin, but I don't have the file yet, to reinstall it.


Namit Agarwal Thu, 10/07/2010 - 17:39


You can download the VPN Client image from the CISCO Website. Follow the path

Support > Download Software > Security > VPN > Cisco VPN Clients > Cisco VPN Client > Cisco VPN Client v5.x >

You can download the version using the image file vpnclient-win-msi-

Also if this does not work try the latest release and download the image vpnclient-win-msi-



guijarrelson Fri, 10/08/2010 - 07:24

I can't download the VPN client from your website, because I don't have the permissions:
