If this is your first visit, take your time and look around. Here are some things you might be looking for:

• SasLibEx: a library that can simulate the Secure Attention Sequence (Ctrl-Alt-Del) but it can even unlock a workstation or session without entering or needing the user’s credentials (and many more things).
• Who locks my file?
• Patch 32 bit Windows to use the full 4 GB (and even more) memory
• Patch Terminal Server to allow more Concurrent Sessions: 2003, Windows XP X64, 2003 X64, 2008, Vista
• Some of my freeware tools such as LaunchRDP, RDP Password Encryption, Active Directory Excel Addin, RDP Clipboard Fix (well this list can go on and on, see also the Downloads section).

I got the following error while installing Exchange 2010: “There are no more endpoints available from the endpoint mapper. (Exception from HRESULT: 0x800706D9)”

I looked up HRESULT 0x800706D9 which is defined in winerror.h as EPT_S_NOT_REGISTERED with the same error text.

I looked at the ExchangeSetup.log in C:\ExchangeSetupLogs and this indicates that the error occurs when the install-ADTopologyService cmdlet tries to add some rules to the firewall:

The Windows Firewall service was disabled, so I set it to Automatic, started it and enabled it and then the setup ran without errors

Note that I am using my own Access Point here so I am not actually cracking someone else’s WEP Key.

Requirements:

• back|track Linux distribution
• USB WiFi card (most internal WiFi cards will not work)

In this post I am using the 32 bit back|track 5 VMWare image which you can use with VMWare Workstation or VMWare player.

After starting the back track Virtual Machine you can login with username root and password toor

Then type startx to start the X Window System (the Graphical Interface):

Before you go on, you need to Connect your WiFi card to the Virtual Machine using the Removable Devices menu:

Now start a Terminal using the Icon in the top bar and verify that your WiFi card is visible to back track using the command

airmon-ng

Note the interface name, I will assume it’s wlan0 from here.

Then enable this interface for monitoring with the following command:

airmon-ng start wlan0

Monitoring is now enabled on a special interface, I will assume it’s mon0 from here.

First we will see which networks are available:

airodump-ng mon0

Wait a little while to get a list of the available networks and their encryption types. This post is about WEP encryption so look for a network that has WEP in the ENC column:

We need the BSSID and the Channel in the next command:

airodump-ng -w wepkey –bssid E2:F8:47:CC:84:0C -c 6 mon0

Now we are capturing packets and we need about 20.000 data packets so just let it run for a while (note that there’s needs to be traffic in order to get data packets):

When there are enough packets captured we can stop the capture with ctrl-c. Use the dir or ls command to view the generated files, we need the wepkey-01.cap file in this case.

The actual decyphering of the key is done with the command:

aircrack -ng -a 1 -b E2:F8L47:CC:84:0C wepkey-01.cap

aircrack returns almost immediately and found the key “12345678ab” which is correct:

Conclusion: You shouldn’t use WEP since it can be hacked within a few minutes.

I bought a Dell Wireless 5530 HSPA Mini PCI card for my Dell Precision M4500 laptop.

This is a small expansion card that works together with the built in SIM card slot that is present in most Dell (Business) laptops.

This SIM card slot is usually located near the battery compartment:

The card was installed in a few minutes since the antenna cables were present already and on my laptop I only needed to remove the backcover with just one screw.

Then I wanted to install the required software but this card is not officially supported in the M4500 (I bought this card because it was much cheaper on ebay).

So I took the driver from the M4400/Latitude E range, labeled R251153 but I got this error message when installing:

The problem is that the installer checks if the combination of the Mini PCI card and the laptop is authorized by Dell. For this purpose the installer extracts two custom executables to the temp folder. In my case the folder was %temp%{85A2C545-B193-4053-8F3E-BB1527A73676}.

The files are: driver_auth.exe and devcon.exe. driver_auth.exe decrypts a file that is delivered with the installation package named dell_wwan_sysID.dat.

Although it wouldn’t be very hard to patch driver_auth.exe to our likings we would need to repack it in the original msi, that in turn is packed in an Installshield .cab file.

So I figured it would be easier to patch the msi and remove the check. I used Microsoft’s Orca tool for this.

The MSI was extracted to %temp%\{A9664DEE-892B-4461-9E86-4EBAF86F69C2}\Dell Wireless HSPA Mini-Card Drivers.msi.

Here comes the step by step process:

Start the Dell installer until you get the error message above, do not click OK but leave the message on the screen.

Open this MSI file in Orca and remove the following sections:

CustomAction | Authenticate:

InstallExecuteSequence | Authenticate

InstallUISequence | Authenticate:

Now Save the MSI, DO NOT USE Save As but overwrite the original MSI, and Install it.

Then click OK on the Error Message from the Dell Installer and finish the install.

Final step is to reinstall the software completely by running the Dell Installer, it will notice that it’s already been installed so it will do a full install now without complaining.

That’s all folks!

I am interested in what content my readers like so these ratings (and of course comments you leave) indicate what kind of articles you like and which you don’t.

However some people feel the need to abuse this, take a look at this:

Someone felt it was necessary to rate a lot of articles with the lowest possible rating (1) meaning they are all crap.

The IP Address of this voter is 192.33.238.14:

Let’s check what this IP has voted in MySQL:

So this voter rated 10 articles within 36 seconds so I assume he/she didn’t even bother to read the articles at all!

As a final step let’s check who owns this IP:

I somehow know this company.

I suspected it was a database problem so I went to phpMyAdmin and did a check on all tables:

Even though MySQL reported all tables to be okay, I tried to repair the wp_options table since this is a common issue with WordPress and indeed this fixed the problem!

The idea was that my kids can use it as a game computer but tonight I couldn’t resist and I played some of the old games.

Do you remember International Karate+?

It’s still a very nice game to play with excellent gameplay even though it seems that my Suzo Arcade joystick has had it’s best time (Luckily I have a 2nd one somewhere but I can’t find it).

I also noticed there is an online flash based clone of International Karate+.

It’s not’s as good as the real thing especially in the gameplay but it’s done very well.

I noticed that I updated this tool sometime after the original post but never uploaded it here. The most important changes are:

• When using ChDrvLetter without parameters it will list the currently assigned Drive Letters and Volumes:

ChDrvLetter v1.4 (c) Copyright 2008 by Remko Weijnen (www.remkoweijnen.nl)

Assigned Letters: [ACDZ]

Volume 0
Letter: C:\
Label :
Device: \Device\HarddiskVolume1
Name : \\?\Volume{c3acae19-dc1f-11df-8130-806e6f6e6963}\
Type : DRIVE_FIXED

Volume 1
Letter: Z:\
Label :
Device: \Device\CdRom0
Name : \\?\Volume{c3acae1c-dc1f-11df-8130-806e6f6e6963}\
Type : DRIVE_CDROM

Volume 2
Letter: A:\
Label :

Label : DATA
Device: \Device\HarddiskVolume2
Name : \\?\Volume{d45237f1-dc21-11df-8d8f-005056ae0001}\

• There is a new DELETEONLY parameter that can be used to delete an existing Drive Letter assignment

ChDrvLetter DELETEONLY Letter
can be used to delete a drive letter Assignment

Example:
ChDrvLetter DELETEONLY D

• the CDROM parameter can be used to change drive letter assignments for cd/dvd players:

ChDrvLetter CDROM Letters
can be used to assign drive letters to CD and/or DVD drives (because they have
no label when no cd/dvd is inserted

Example:
ChDrvLetter CDROM ZYX
Assigns Z to the 1st found CD/DVD drive, Y to the next etc.
