I've been able to reproduce this problem using two different installs of linux as the 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
windows xp professional sp2
-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
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.
