ConfigMgr : Dell Latitude E7240/7440 wdf1000.sys BSOD

In further testing on the E7x40 series I’ve run in to Blue Screen errors under Windows 7. Using DaRT Crash Analyzer the offending driver looks to be the Intel Management Engine Driver, TeeDriver.sys:

To resolve, download and install:

Import this driver to SCCM and integrate this into the SCCM driver pack to resolve this on future deployments.

Windows 8.1 : Modern Applications and Cookie-Based Authenticated Proxies

I’ve been testing Windows 8.1 within the organisation for a few weeks – and have been experiencing issues with Modern (Metro) Applications when interacting with our zScaler proxy. The issue with this, amongst other cookie-based authenticated proxy servers, is that Modern Applictaions do not support the use of the users cookie to provide authentication to the proxy. Essentially we would see issues such as:

  • The Windows Store displays no images / complained about not being connected to the Internet
  • Application downloads would fail from the store
  • XBox Music and other streaming applications would play no content

For example:

UE-V 2.0: End-to-End Deployment

Microsoft User Experience Virtualization is a relatively straightforward technology to deploy – there is no server-side application installation, all you need is a couple of file shares and then an agent deploying to each device. The components of my production deployment are as follows:

DFS shares, each with offline files disabledUE-V 2.0 doesn’t play well with offline files:

\\domain.local\DFSNOCACHE\UEV2\Settings : All Users that use computers with the agent should have permissions as outlined here

\\domain.local\DFSNOCACHE\UEV2\Templates : All Computer Objects that have the agent should have read permissions, again as outlined here

Rather than using all of the built-in templates, copy those that are of interest into the Templates folder, and ensure that you do not register the MS templates at Agent Install (I’ll show you in a moment). I encountered lots of issues with the built-in templates and Office 2013 – see here. For reference I copied:

When it comes to settings synchronisation, you have two options:

  1. Per-User – ensure the users gets the same look and feel across multiple devices
  2. Per Device – ensure all users of one device get the same look and feel

We opted for a per-user model, this means that if a user loses their device they can logon to a new laptop – one which we have associated their user account with in SCCM – their personal, user assigned applications install via SCCM and UE-V 2.0 applies their personal settings such as IE homepage, Outlook Signatures, Desktop Background. Essentially its a poor-man’s USMT, it will never provide the incredibly rich capability of USMT as on a per-user basis we’re seeing <5MB per user, in fact typically 2MB.

Finally, to deploy the agent via SCCM use the following command – be sure to update the UNC path with a valid location! The important parts here are:

  • RegisterMSTemplates=FALSE ; ensures the built-in templates rae not imported
  • SettingsStoragePath=\\<UNC PATH>\Settings\^%username^% ; the DFS share to store per-user settings. Command is specifically for SCCM deployments, ^%username^% will ensure the username environment variable is used.
  • SettingsTemplateCatalogPath=\\<UNC PATH>\UEV2Templates ; the DFS share with the XML UE-V 2.0 templates
AgentSetup.exe /quiet /norestart /log "%temp%UE-VAgentInstaller.log" RegisterMSTemplates=FALSE SettingsStoragePath=\\domain.local\DFSNOCACHE\UEV2\Settings\^%username^% SettingsTemplateCatalogPath=\\domain.local\DFSNOCACHE\UEV2\Templates

Remember, with UE-V 2.0 settings are synchronised in different ways:

  • Logon/Logoff
  • Lock/Unlock
  • Launch/Close of an application

ConfigMgr : Dell Latitude E7240 and E7440 wPci.sys

I extended the Windows 7 and Windows 8.1 Task Seqeucnes today to support the latest Latitude models – the E7240 and E7440. Both are nice machines.

The Windows 7 builds, despite importing the Driver Pack supplied by Dell, were failing with the error:

Windows failed to load because a critical system driver is missing or corrupt. WindowsSystem32driverswPci.sys

After removing the associated drivers from both the E7240 and E7440 Driver Packages the build issues were resolved – ironically, there were no unknown devices following completion of the Task Sequence.

The driver to remove is “wPCI Up stream port (marlon)

Don’t forget that for Windows 7 you’ll also need the KMDF 1.11 driver, integration instructions here:

UE-V 2.0 : Excel There was a problem sending the command to the program.

It’s never as simple as it should be with Microsoft Technologies – UE-V 2.0 is another good example of this. We’ve been trialing this internally for a couple of weeks and noted a strange issue affecting Office 2013:


There was a problem sending the command to the program.

Update 14/02/2014: There is now a hotfix for this issue:


ConfigMgr : Windows 8, UEFI and VMWare ESXi 5

So in my free time I’ve been looing at UEFI deployments of Winodws 8.1, including Secure Boot, on Dell E6330/E6320 platforms. I noticed that our ESX 5 environment supports EFI firmware, so figured this would be an ideal test bed to ensure that the Task Sequence itself works… not so. I ran into an issue where the deployment to an E63x0 works just fine, however an EFI-enabled Virtual Machine fails to build, getting stuck at the blue Windows Logo during a reboot within the “Setup Windows and ConfigMgr” Task Sequence Step – as below.

This appears to be an VMware EFI issue as reviewing the partition data/boot config shows no issues, and there are no issues/errors reported in the SMSTS.log – the machine simply reboots to perform the next part of the Setup Windows and ConfigMgr step and never boots properly.

A Legacy BIOS deployment of the same TS works without issues to a VMWare Virtual Machine and, as as stated previously, a UEFI/Secure Boot deployment to a Dell Latitude E63x0 works without issue.

Note that I’m running ConfigMgr 2012 SP1 CU3.
