Hello,
I'm French so sorry for my communication,
My new computer with Vista 64 meet recently some reboot problems. I installed recently special software :
Virtual PC, VMWare, Daemon Tools, NCP Secure Client (a VPN client), kaspersky internet security is always my security program for a long time (avp.exe on the dump...)
There are 9 dump files but it is almost the same.

I need all the programs I talked about, so I ask you to have the culprit.
Thanks for helping. If you need more informations I will bring it.

Edit : I uninstalled and reinstalled Kaspersky, no more BSOD yet... Strange, I hope it will stay good.

All errors are 0xD1 and these are almost always caused by faulty drivers. The driver cited in every minidump as the probable cause is ncplelhp.sys and except for one place there was was nothing on the internet concerning this driver.

Kaspersky isn't your issue because ncplelhp.sys prevents the Kaspersky driver kl1.sys from loading and interferes with the process avp.exe which belongs to Kaspersky as well. This is why when you uninstalled and reinstalled Kaspersky you most likely undid whatever conflicts were taking place bewtween the two.

ncplelhp.sys is a driver for NCP Virtual Tunnel Adapter which is part of the NCP Secure Client Adapter by NCP Engineering GmbH.

Question: Is your Kaspersky anti-virus only or is it their security suit? The reason I ask is because NCP has a built in firewall and two firewalls loaded at the same time will cause conflicts and system crashes.

(It crashed again)

It is Kaspersky Internet Security so there is a firewall. Thanks for help, I disable it. Should I disable Windows firewall ? I don't know which one to keep.
It seems that NCP firewall was disabled yet... strange.

Here is the rule about security software that provides resident protection: One antivirus, one firewall, one antispyware (plus a router which ias absolutely essential). When I say Resident Protection I mean the kind that is running in the background protecting you PC.

Three firewalls are going to cause all kinds of issues. Disable the other two and keep one. I know nothing about NPC nor how good the firewall is and it might have disabled itself becauswe you already had two running.

Vista's firewall is considerably better than XPs. XP's is actually very poor. You may be okay with Vista. I do know Kaspersky is excellent as an antivirus but I know little about their firewall.

I abled only NCP firewall, but there is a new BSOD.

What should I do ? I can't disable the service "NCPRWSNT.EXE" because I need this to connect.
It crashed when I try to download a lot (>3.5MB/s) with Firefox.

Your error is 0xD1 and once again the driver ncplelhp.sys is cited as the issue and it is blocking your Kaspersky from loading certain vital drivers for the antivirus part of your suit.

Even though you disabled Kaspersky's firewall you must keep in mind the drivers are still present from its firewall.

Try updating your NCP product. Also, disable its firewalll and re-enable Kaspersky's and see if that brings stability.

I found that. I uninstalled Kaspersky Anti-Virus NDIS Filter. In few days I will come back here to say if I meet other problems or not.

Your antivirus protection won't be compromised, will it?

It is not critical, I prefer that than random BSOD always. It makes me crazy.
