DeviceDriver Installation and Removal with Devcon

Today i came across a problem with a device driver on a remote computer.
Normally we install drivers with RES Automation manager and Dpinst, but it had failed on this machine and with remote device management you cannot remove devices.
Therefore i searched in the Windows Driver Development Tools for a tool that can do just that.
So i found Devcon1

Thinapp: Child process keeps SandBox locked

One of the best practices when packaging with ThinApp includes verifying no processes are left running that lock the Sandbox when you shuts down the application. You can simply verify this by trying to delete the package’s Sandbox. If it is locked and you cannot delete it, some process is still running.
To determine wich process locks the sandbox i use Process Explorer.

In my case the child process ‘svchost.exe’ kept the sandbox locked.
Because it was running outside of the thinapp the ‘OnLastProcessExit function’ is never called.

Error 242 when deploying image with HP Device Manager 4.4

When i tried to update/deploy an image from HP Device Manager 4.4 to a Compaq 6720T it constantly failed with the following error:

Fail to execute PushImage task
ErrorCode: 242, Error Detail: Failed to seek image file to end
Fail to execute common task
ErrorCode: 242, Error Detail: Failed to seek image file to end

After some troubleshooting i came to the conclusion that the HPDM agent is not up to date on the client. Make sure that your Agent and your HPDM are the same version, otherwise you can not image from HPDM. 
In HPDM there is the Agent tab, drag and drop the Update Agent template on the unit.  Once that is complete you should be able to image your system.

Use Windows 7 as Virtual Router

Sometimes it’s just handy to use you’re laptop as a Wifi Hotspot. There are a lot of applications to do that, but the ones that actually work cost a bit. So why not use the built in utility of Windows 7? This is how you can do that.

  1. Open a command prompt with administrative privilges
  2. Enter the following command: netsh wlan set hostednetwork mode=allow ssid=WIN7 key=password This will create a wireless access-point with SSID of “WIN7”
  3. Open Networks and Sharing Center and enable the newly created wireless connection.
  4. Share the interface with an internet connection to the newly created wireless connection.


Now you can start the interface with the following command: netsh wlan start hostednetwork

VMware ThinApp package crashes with VBS.

For the intergration of VMware ThinApp applications into RES Workspace Manager, a custom VBS is required in the root of the Setup Capture files folder.
The following code must be present in the script:

Function OnFirstParentStart
WaitForProcess ExecuteVirtualProcess(GetEnvironmentVariable(“pwrgrids”)),0
End Function

But some ThinApp applications failed to start after that, or any vbs script was added to the build.

Migrating Pop3 Connector SBS 2003 to SBS 2008

After a migration of SBS 2003 to SBS 2008 i encountered some problems assigning a pop3 connect mailbox to an exchange user.
No (migrated )mail enabled users appeared in the drop down list.

Only new user who are created with the Windows SBS Console seem to populate the list.
One way to populate the list is changing the msSBSCreationState attribute on the user.
Just open adsiedit.msc and browse to the users you want to populate the list and click preferences.
Then go down to the msSBSCreationState attribute and click edit and fill in the value “Created”

Ok out of all windows and open up the pop3 connector console again.
You can now see the edited account(s) in the dropdownlist

Ronde van Vlaanderen

Aankomende Zaterdag is het dan zover, de eerste toertocht
klassieker van het jaar. En wat voor één!

De ronde van Vlaanderen.

De trainingskoersen op zaterdag zijn best goed gegaan,  wat extra punten gepakt met een 11de plek en eindklassement een 30ste . Ondanks dat ik twee keer niet ben geweest toch een aardige klassering.

Zit ook rond de 2000 trainingkm’s, dus de conditie is aardig te noemen. Nog niet geweldig, maar de training vorige week in Limburg ging wel ok voor de tijd van het jaar.

De juiste banden heb ik inmiddels ook uitgekozen voor de tocht, de Vittoria Open Pave Corsa CG. Dit is een zogenaamde vouwband zodat deze makkelijk meegenomen kan worden. De band is wat breder, dit maakt rijden over de kasseien net iets aangenamer. Ook is het karkas van de band behoorlijk sterk, wat de kans op lekrijden weer wat kleiner maakt.

Heb er veel zin! Op de site komt volgende week een verslagje van de tocht.
