Process Explorer, Remote Desktop causing blue screens on 64-bit Windows Server 2008 R2 guest

[Matt]

I have a newly-created guest that I installed from a 64-bit Windows Server 2008 R2 with Service Pack 1 installation disc. It has no additional applications or Windows components installed beyond the defaults, and the only configuration changes I've made are setting the computer name, static network configuration, and a few changes in local Group Policy. I have been experiencing reproducible blue screens when performing either of the following actions:

• Running (or, usually, exiting) Process Explorer 14.12
• Logging out of a Remote Desktop session (connected to Windows' RDP server, not VirtualBox's)

These blue screens do not occur every single time I perform one of the above actions, but usually every third or fourth. Most often the stop code is 0x0000001A MEMORY_MANAGEMENT, but occasionally I'll see 0x0000000A IRQL_NOT_LESS_OR_EQUAL. I've experimented with versions 4.0.8, 4.0.0, and 3.2.12 of VirtualBox Guest Additions, as well as no Guest Additions installed at all, and I'm still seeing this problem.

The host is running 64-bit Ubuntu Server 11.04 "Natty Narwhal" and I use VBoxHeadless to run virtual machines. I used to have a 64-bit Windows Server 2008 guest that worked fine with VirtualBox 3.2 but began experiencing similar blue screens after upgrading to 4.0, which is why I'm trying to isolate this problem now. Today I upgraded to version 4.0.10 of VirtualBox and VirtualBox Extension Pack from 4.0.8 and this issue is still present.

To produce this Process Explorer blue screen for which I added attachments, I performed the following steps:

1. Restored a snapshot taken immediately after installing Windows and making the configuration changes noted above
2. Powered on
3. Logged in to Windows
4. Copied Process Explorer from an SMB share to the local Desktop
5. Double-clicked to launch procexp.exe and Windows blue-screened soon thereafter (within seconds)

I will upload logs and dumps for the MEMORY_MANAGEMENT blue screen and Remote Desktop blue screens as I am able to produce them.
