Converting photos very slow and high CPU consumption with Synology DSM 4.1

After the installation of the Photo Station application on my Synology ds413j, I transfer all my photos to the photo's folder created by this application.

So I transfer my photos to the NAS and then I can see the NAS CPU running 100% for a very very long time...

You can follow the "Conversion Progress" of the photos but nothing seems to be converted despite the fact the high CPU rate.

You can follow these 4 steps to solve the problem :

1) Enable SSH on the NAS.

Control Panel > Terminal > check the Enable SSH Service box.

2) Connect to the NAS (with a ssh client like putty or mRemoteNG) with the root account 

3) Edit the "/usr/syno/etc/thumb.conf" and "/usr/syno/etc.defaults/thumb.conf" files and comment or remove these lines : 

[thumb 1280]

4) Restart the service

/usr/syno/etc/rc.d/ restart

Cheers !

Add a driver to a wim image (offline and online)


2003 environment

1) Open a command prompt.

2) Go to the directory where you can use imagex utility.
cd "c:\Program files\Symantec\Ghost\PETools\x86\"
3) Mount your wim image in a directory you created for this purpose
imagex /mountrw "D:\Program Files\TFTPBOOT\boot\winpe.wim" 1 d:\IMG\mount
4) Add your driver
peimg.exe /inf=D:\IMG\drivers\VISTAX32\E1K6032.INF /image="d:\IMG\mount"
5) Unmount an commit the changes
imagex /unmount /commit D:\IMG\mount

2008 environment

In 2008, you can use DISM (Deployment Image Servicing and Management), and the best is that this tool is integrated with Windows 2008.

1) Open a command prompt.

2) If you have multiple editions in your wim image, get the index of edition to be modified
dism /get-wiminfo /Wimfile:C:\tmp\winpe.wim
3) Mount your wim image in a directory you created for this purpose
dism /Mount-Wim /WimFile:C:\tmp\winpe.wim /Index:1 /MountDir:C:\tmp\mount
4) List out drivers already present in this wim
dism /image:C:\tmp\mount /get-drivers
5) Add your third party driver (in my case it was an Intel 82579LM and 82579V Gigabit Ethernet Driver)
dism /image:C:\tmp\mount /add-driver /driver:C:\tmp\WIN7x32\E1C6232.inf
6) Unmount and commit your image
dism /unmount-Wim  /MountDir:C:\tmp\mount /commit



In my case, I had to add a NIC driver to boot in PXE/TFTP mode and make an image of a laptop with GostCast Server.

When I boot on LAN, in Ghost32, I do not have network. So I dynamically loaded the drivers provided by HP with the tool drvload that I have added to my wim image.

I downloaded the drivers, saved on a USB drive and loaded the key into the laptop. Then I loaded the drivers for vista, and it does not works. I finally used drivers for Seven and when I try ipconfig /renew, the laptop get an IP. Then I add this driver to my wim image with dism.

In your winpe environment, type

drvload.exe inf_path

Centreon Could not find DEFINITIONS :: = BEGIN statement in MIB file!

To recover the traps sent by my SAN MSA2012FC (, I tried to add a MIB (found here : in Centreon.

Here is the error I encountered:

Could not find DEFINITIONS :: = BEGIN statement in MIB file!

After catching a headache I found the solution... 

beginning of the file

Last edit date: November 10th, 1999
   IMPORTS     IpAddress, TimeTicks, experimental         FROM RFC1155-SMI     OBJECT-TYPE         FROM RFC-1212     DisplayString         FROM RFC1213-MIB     TRAP-TYPE         FROM RFC-1215;

Netbeans - JVM creation failed

You tried to launch your Netbeans IDE and you encountered this error: 

JVM Creation Failed
In my case, under Windows XP x86, I modified this line (in configuration file C:\Program Files\NetBeans 7.0\ etc\netbeans.conf)

->netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=384m -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true"

Strict replication consistency should be enabled on all domain controllers in this forest

You run a BPA on your "Active Directory Domain Services" role and you obtain this warning:

Strict replication consistency should be enabled on all domain controllers in this forest
Issue: Strict replication consistency is not enabled on the domain controller SERVERNAME
More information about this best practice and detailed resolution procedures:
(When a domain controller in your Active Directory environment is disconnected from the replication topology for an extended period of time, all objects that are deleted from AD DS on all other domain controllers might remain on the disconnected domain controller. Such objects are called lingering objects. When this domain controller is reconnected to the replication topology, it acts as a source replication partner that has one or more objects that its destination replication partners no longer have. Problems occur when these lingering objects on the source domain controller are updated and these updates are sent by replication to the destination domain controllers. A destination domain controller can respond in one of two ways:

    If the destination domain controller has strict replication consistency enabled, it recognizes that it cannot update the object (because the object does not exist), and it locally halts inbound replication of the directory partition from that source domain controller.

    If the destination domain controller does not have strict replication consistency enabled, it requests the full replica of the updated object, which introduces a lingering object into the directory.

What I do:

1) You have to remove lingering objects

/removelingeringobjects <Dest_DSA_LIST> <Source DSA GUID> <NC> [/ADVISORY_MODE]

Dest_DSA_LIST (you can enter the dns name of the server or the distinguished name)

DSA_GUID : To find this one, type :

                      repadmin /showrepl

                     And copy the DSA object GUID value
NC: It's your naming context (example: DC=CONTOSO,DC=COM)

The Advisory_mode logs lingering objects in Event ID 1388 or 1988 (

2) Enable strict replication consistency

The syntax is : repadmin /regkey DC_LIST {+|-} key

--> I used "repadmin /regkey SERVENAME +strict" 

The AD DS BPA should be able to collect data about Group Policy Results setting "Access this computer from the network" from the domain controller...

You run a BPA on your "Active Directory Domain Services" role and you obtain this error:

"The AD DS BPA should be able to collect data about Group Policy Results setting "Access this computer from the network" from the domain controller SERVERNAME"

Open "Active Directory Module for Windows PowerShell" then type:
1) cd C:\Windows\System32\BestPractices\v1.0\Models\Microsoft\Windows\DirectoryServices\
 2) .\DirectoryServices_model.ps1

From Microsoft Technet
 a) Look for “Cannot translate account name to SID” in the output, where is the name of the account that was failed to translate. 
b) Troubleshoot why this account cannot be translated to a SID 

In my case, it was a problem with an account that had been set on "Default Domain Controllers Policy" policy and that no longer existed in the domain. 

Tip: To find what policy contains SID problems, try to backup all your GPOs 

1) Open "Group Policy Management" (or type gpmc.msc in Start>Execute) 

2) You'll see an error message appears in the GPO which contains not mapped SID --> remove the bad SID(s).

Best practice : protect OU from accidental deletion in 2008R2

In 2008 domain, when you create an OU, it is protected by default from accidental deletion.

But if you have got OU presents from a migration or something else these OUs are not protected against deletion.

 You can do it via the interface "Active Directory Users and Computers", right click on the "OU>properties>object>check the box 'Portect object from accidental deletion'".

If you can't see the "object" tab, it's because you have to activate the advanced features view. In ADUC, "View>Advanced Features".

If you have a lot of OUs, you would make this by a script...
So, open "Active Directory Module for Windows PowerShell" and enter this command

Install NPS (Network Policy Server) - Radius

The VPN (Virtual Private Network) allows users to connect from the Internet in their company. This connection is encrypted in a tunnel, so that data can not be recovered by a possible pirate.
The authentication procedure may be made either by e-certificate or by account / password. We must therefore choose the method that works for you.

The client connects to the VPN server, which authenticates with the Radius server (Remote Authentication Dial-In User Service) Central. After authentication, the client received his VPN company IP address, which allows access to company data, as if it were on the site.

Authentication: verification and control of User ID and Password in the Radius Client
This is a protocol used by machines to authenticate an user of a service or providing feedback on this user (traffic volume, connection time, ...). By extension, it is called Radius server or proxy server to tell server or proxy using the Radius protocol to communicate.


On Windows Server 2008R2 service Radius (IAS) was replaced by NPS (Network Policy Server).

How to find HBA WWN number on ESX server

Select the ESX host in the VI client > Select the Configuration tab > Select Storage Adapters> and on the right hand side the storage adapters are listed.  If you select one it should list the details of the hba in the section on the bottom right of the screen.

Roomba 563 - Error 2 - clicking noise - constantly Asking for Brushes to Be Cleaned

You have a roomba and you love it. But suddenly, it don't want to clean your home and constantly asking for brushes to be cleaned.

The roomba website say "send back to support". Well come on....

Let's go nuts !

The first thing to do is return the beast.

Pull out the tray and brushes. Unscrew the 4 screws (blue arrows).

Ok, remove the battery.

Unscrew the 4 screws (blue arrows).

You can remove the CHM (Cleaning Head Module). Roomba without its CHM

The CHM.

The blue bin is flexible. You can easily undo the two tie holding the CHM in itself (green part). This will allow you to access this. Unscrew the 6 screws of this cache.

Look at this horror ... But I have a big dog, huh that's why it's so filthy, I assure you :-p So now, clean up all this careful to put out properly and put each element in its place, and miracle! The robot no making longer this awful "clack clack" noise ;-)
