If you want to see a couple of nice videos about Microsoft Windows 2008 and Active Directory check the links below:

Part 1: In this video from TechEd 2008, Microsoft senior technical product manager Justin Graham discusses some of the lesser known improvements made to Active Directory with Windows Server 2008. Here you'll get details on features such as stickiness prevention and fine-grained password policies, plus info on what new auditing enhancements to AD mean to administrators.

Part 2: In part two of our interview on Active Directory from TechEd 2008, Microsoft senior technical product manager Justin Graham explains how the read-only domain controller can help improve branch office security. Graham also provides details on the application compatibility considerations that administrators should be aware of before deploying an RODC with Active Directory in Windows Server 2008.

Via NTPRO.NL:

Chris Skinner, a Technical Trainer over at VMware created a document for clustering VirtualCenter 2.5 with MSCS. Feel free to distribute to clients and colleagues. A special thanks to Seva and Charu for challenging Chris to do this based on their VC2.0 document. This paper documents the steps to successfully implement a high availability solution for VirtualCenter 2.5 using Microsoft’s cluster services. There are some basic requirements to start the process. Microsoft requires Active Directory for cluster services. Additionally, Windows 2003 Enterprise server or higher will be necessary. This document was compiled from several sources. It demonstrates creating a VC cluster on the same ESX host (cluster-in-a-box) with a SAN-based quorum disk. The hyperlinks at the end of the document has more detailed information for other types of configurations, such as, cluster-across-boxes and physical-to-virtual.

From RTFM Education:

"Simon Ruzgar of autonation.com has very kindly sent RTFM a handy little script - based on some post-P2V scripting I did donkey’s years ago - I’m mean back in the ESX2/VC1/P2V2 era. Here’s the problem it fixes: When you P2V you loose your IP settings from your Windows “Local Area Connection”, because Windows hides the old physical NIC, and shows a new vmxnet NIC inside the virtual machine.

Here’s what Simon’s script does: You run it on the physical box prior to conversion, it reads the IP configuration and pipes it to a text file. You then carry out your P2V. Once that’s completed you re-run the script which then reads your “lost” IP configuration from the text file - and puts them back behind you new local area connection."

You can download the script here.

Back in February I wrote a post about the VMware Tools and Utilities I use to administer our VMware environment. Now, via vmware-land.com we get the following list:

1-Putty - Telnet and SSH client for remotely connecting to the ESX service console
2-WinSCP and Veeam FastSCP - SCP clients for browsing ESX server file systems and transferring files to/from ESX hosts
3-VI3 SnapHunter and SnapAlert - Utilities that can report all running snapshots on ESX hosts including name, size and date. Can also automatically email reports and optionally commit snapshots
4-VI Scripted Backup Utility - A backup utility that is run from the Service Console that provides VMDK level backups of any VM on storage accessible by the host
5-MCS StorageView - A utility that displays all the logical partitions, operating system, capacity, free space and percent free of all virtual machines on ESX 3.x or Virtual Center 2.x
6-SSH Plug-in - A VI client plug-in that integrates an SSH console directly into the client
7-Storage VMotion Plug-in - A VI client plug-in that extends the client’s functionality by providing an integrated, graphical tool that can be used to invoke storage VMotion (SVMotion) operations
8-VMotion Info - A program that will collect Vendor, Model, CPU Types and the CPU feature bits from all hosts to check for VMotion compatibility
9-VMCdConnected - Scans all Virtual Machines and shows if they have a CD connected to it. After scanning the VM’s you can disconnect all the CD’s with a click of a button
10-VMware Converter – (Performs hot and cold conversions of physical and virtual servers to virtual machines. Also converts image formats

Since a second SCSI adapter is mandatory for Microsoft Clustering Services running in VMware, and it will also provide better performance for any I/O intensive virtual machine like a database server, file server, etc; adding a second controller may be a necessity or valuable option for us. Here is how it can be done:

  • After creating the VM we need to “Edit” its settings and select to “Add...” a new device



  • We then choose “Hard Disk” (not SCSI device) and click “Next”



  • We accept the defaults and click “Next” (unless we whish to re-use an existing vDisk)



  • We input the size and move on to the next screen



  • In here we need to select a different SCSI node so…



  • We are going to choose “SCSI (1:0)” and then click “Next”



  • Now we complete the Add Hardware Wizard by clicking “Finish” and then…



  • We will be back to the VM Properties where, after clicking “OK”, the changes are going to be committed



Note: If we select to edit the VM one more time, we will see the second SCSI Controller

New VMware Releases

Posted by Gabriel Macie… Mar 18, 2008

VMware Server Version 1.0.5 (free) / http://www.vmware.com/download/server

  • A security vulnerability in OpenSSL 0.9.7j could make it possible to forge a RSA key signature. VMware Server 1.0.5 upgrades OpenSSL to version 0.9.7l to avoid this vulnerability.
  • An internal security audit determined that a malicious user could attain and exploit LocalSystem privileges by causing the authd process to connect to a named pipe that is opened and controlled by the
  • malicious user. In this situation, the malicious user could successfully impersonate authd and attain privileges under which authd is executing.
  • An internal security audit determined that a malicious user could exploit an insecurely created named pipe object to escalate priviliges or create a denial-of-service attack.
  • This release updates the libpng library to version 1.2.22 to remove various security vulnerabilities.
  • A vulnerability in VMware Workstation running on Windows allowed complete access to the host's file system from a guest machine. This access included the ability to create and modify executable files in
    sensitive locations.
  • The authd process read and honored the vmx.fullpath variable in the user-writable file config.ini, creating a security vulnerability.
  • The config.ini file could be modified by non-administrator to change the VMX launch path. This created a vulnerability that could be exploited to escalate a user's privileges.

VMware Workstation 6.0.3 / http://www.vmware.com/download/ws

  • On Windows hosts, if you have configured and enabled a shared folder, it is possible for an attacker to write arbitrary content from a guest system to arbitrary locations on the host system.
  • An internal security audit determined that a malicious user could attain and exploit LocalSystem privileges by causing the authd process to connect to a named pipe that is opened and controlled by the malicious user. In this situation, the malicious user could successfully impersonate authd and attain privileges under which Authd is executing.
  • This release updates the libpng library to version 1.2.22 to remove various security vulnerabilities.
  • This release updates the OpenSSL library to address various vulnerabilities to denial-of-service attacks and buffer overflows.
  • Workstation 6.0.2 allowed anonymous console access to the guest by means of the VIX API. This release, Workstation 6.0.3, disables this feature. This means that the Eclipse Integrated Virtual Debugger and the Visual Studio Integrated Virtual Debugger will now prompt for user account credentials to access a guest.

VMware Player 2.0.3 (free) / http://www.vmware.com/download/player/

  • On Windows hosts, if you have configured and enabled a shared folder, it is possible for an attacker to write arbitrary content from a guest system to arbitrary locations on the host system.
  • Ubuntu 7.04 virtual machines sometimes power off unexpectedly if paravirtual kernel support is enabled.

VMware ACE 2.0.3 / http://www.vmware.com/download/ace/


Also, you can find VMware Server 2.0 Beta (free) here:

I have been using mRemote for two months now and I mainly like it because:

1) It supports rdp, vnc, ssh, telent, rlogin, raw, http/s and ica, so you can check your web sites, connect to the ESX Server / Unix farm and manage your Microsoft Infrastructure through RDP using only one window

http://bp3.blogger.com/_aQ4lu_8WP_o/R9hDXNQ526I/AAAAAAAAAXo/ZzV5ahq1ZuE/s200/mRemote.2.JPG

http://bp2.blogger.com/_aQ4lu_8WP_o/R9hEJ9Q527I/AAAAAAAAAXw/yleA2b1k9ys/s200/mRemote.5.JPG

2) It will recognize your Putty sessions

3) mRemote can call external applications and tell them what to do with the use of parameters and variables of the currently selected connection

Give it a try and hopefully you will like it too!

Download mRemote at Sourceforge (1)

(1) Be sure to have the .Net Framework installed in advance

A week or so ago, Andrew Kutz made public 2 new client plugins for the VMware Infrastructure 3.5 environment. This week, we are glad to see that the list goes up to 7!


  1. SVMotion: This VI plugin allows VMware administrators to invoke storage VMotion (SVMotion) events.
  2. Add Port Groups: This plugin enables the creation of multiple port groups of any type on an number of ESX servers and virtual switches at once.
  3. Rdp: Allows for RDP from VMware Virtual Infrastructure client right click menu.
  4. Console: Adds a SSH enabled tab named 'Console' when a host system is selected.
  5. KeySniffer: KeySniffer is an example of how VI 2.5 client plugins can be abused. This plugin sniffs all key strokes that occur within the VI 2.5 client and outputs them to C:\viclientkeystrokes.txt.
  6. Invoke: Allows third-party applications to be launched from within the VI 2.5 client using an existing, authenticated session cookie.
  7. 37migrations: The 37migrations plugin was developed in conjunction with 37migrations.com. It increments your VMotion count on the 37migrations server every time a migration event occurs.
This is the link to viplugins.com.
