Bluescreen on mrxdav.sys

[mnelson]

Hello,

I've been able to reproduce this problem using two different installs of linux as the host:

Host:
Ubuntu 7.10, virtual box 1.5.0 from the .deb provided on virtualbox.org
Mandriva 2008.0, virtual box 1.5.0 provided from the mandriva dvd

Guest:
windows xp professional sp2

Setup:
-br0 bridges eth0 and vbox0. host and guest have different ips. networking works.
-vt extensions enabled in bios (have tried enabled and disabled in the vbox software)
-host authenticates using active directory to a w2k domain
-guest is joined to the domain

Issue:
seemingly when i attempt to use a network resource from the guest (this could be browsing a network share, using vnc etc) i get a bluescreen:


If I close the VM and restart it, it will get another bsod right after i logon to the domain.

Any suggestions would be much appreciated. I have, of course, looked up this error message and found a related knowledgebase article as well as a hotfix, but i find it hard to believe that this is the actual problem, based on what the explanation of the issue is.

Thanks

I'd also like to note that i've used the driver for the amd pcnet driver that gets installed with windows, as well as upgrading the driver that is provided with the guest addtions. the bluescreen will occur with either driver installed.

i just received this running windows xp as the host and windows xp as the guest as well.

Same problems for me with virtualbox 1.5.2 and winXP as guest on ubuntu 7.10.

Hi

I had this problem but I fixed it by turning off the WebClient in Windows XP.

My Computer > Right click and select Manage > Service and Applications > Services.

Double click on WebClient. Press Stop button to turn it off and "Disabled" in the "Startup type" menu so It doesn't start at next system boot

johandahl you are the one.

johandahl you are the one.

This worked for me too. I had given up using VirtualBox on Ubuntu Hardy 804 because the shares crashed most of the time.

Disabling WebClient Service seemed to solve the blue screen crash with a reference to mrxdav.sys.

Thanks, Ian

Hmm, good point. That might explain why one of my VMs kept crashing when accessing shared folders and the other didn't. As I modified the installation with nLite, I'm not so sure if I removed the web client. I will certainly remember this.

According to Microsoft's Knowlegde Base article KB832143, it's a "genuine" Windows XP bug, nothing to do with VirtualBox. And with Service Pack 3 you cannot even hotfix it anymore. So: turning off the Webclient service is THE solution now.

BTW I could therefore reproduce the bug on latest VirtualBox 1.6.4 as well.

You kick ass. It worked perfect. All i need now is usb stuff.

Any idea on why none of my usb stuff works?

Modedit: I removed all the caps, no need to shout here.

For USB, see the VirtualBox FAQ. It has links to howto's for Ubuntu and SuSE.
