Difference between VMware ESX and ESXi


It’s been a long debate that everyone has been asked by what is the difference between ESX and ESXi. Most of the admins would have asked this question during interviews and also asked by new learners of VMware virtualization. I decided to post on the topic to give architectural difference always as to compare the different level capabilities between ESX & ESXi.

What is VMware ESX ?

ESX (Elastic Sky X) is the VMware’s enterprise server virtualization platform. In ESX, VMkernel is the virtualization kernel which is managed by a console operating system which is also called as Service console. Which is linux based and its main purpose is it to provide a Management interface for the host and lot of management agents and other thrid party software agents are installed on the service console to provide  the functionalists like hardware management and monitoring of ESX hypervisor.                                                                                                                                         

Graphic Thanks to VMware

What is VMware ESXi ?

ESXi (Elastic sky X Integrated) is also the VMware’s enterprise server virtualization platform. In ESXi, Service console is removed. All the VMware related agents and third party agents such as management and monitoring agents can also run directly on the VMkernel. ESXi is ultra-thin architecture which is highly reliable and its small code-base allows it to be more secure with less codes to patch. ESXi uses Direct Console User Interface (DCUI) instead of a service console to perform management of ESXi server. ESXi installation will happen very quickly as compared to ESX installation.

VMWARE Interview Questions

How to setup Default and Fine Grain Password Policy


One strange thing that still seems to catch a lot of people out is that you can only have one password policy for your user per domain. This catches a lot of people out as they apply a password policy to an OU in their AD thinking that it will apply to all the users in that OU…. but it doesn’t. Microsoft did introduce Fine Grain Password Policies with Windows Server 2008 however this can only be set based on a security group membership and you still need to use the very un-user-friendly ADSI edit tool to make the changes to the policy.

Below I will go through how you change the default domain password policy and how you then apply a fine grain password policy to your environment. The Good news is setting the default password policy for a domain is really easy. The Bad news is that setting a fine grain password policy is really hard.

Update: If you want to set a password complexity setting that is not supported out of the box of windows then it is possible to install a third-party DLL on you domain controllers to achieve this. However there are many caveats to this and it is best you check out the full explanation at http://blogs.technet.com/b/askds/archive/2011/08/05/friday-mail-sack-beard-seconds-edition.aspx#password

How to set a Default Domain Password Policy

Step 1. Create a new Group Policy Object at the top level of the domain (e.g. “Domain Password Policy”).

image

Note: I have elected to create a new GPO at the top of the domain in this case as I always try to avoid modifying the “Default Domain Policy”, see references below.

Reference

TechNet: Linking GPOs

If you need to modify some of the settings contained in the Default Domain Policy GPO, it is recommended that you create a new GPO for this purpose, link it to the domain, and set the Enforce option.

TechNet: Establishing Group Policy Operational Guidelines

Do not modify the default domain policy or default domain controller policy unless necessary. Instead, create a new GPO at the domain level and set it to override the default settings in the default policies.

Step 2. Edit the “Domain Password Policy” GPO and go to Computer Configurations>Policies>Windows Settings>Security Settings>Account Policy>Password Policy and configured the password policies settings to the configuration you desire.

image

Step 3. Once you have configured the password policy settings make the “Domain Password Policy” GPO the highest in the Linked GPO processing order.

TIP: Make sure you inform all your users when you are going to do this as it may trigger them to change their password the next time they logon.

image

Done… told you it was easy….

Note: Even if you apply the password policies to the “Domain Controllers” OU it will not modify the domain’s password policy. As far as I know this is the only exception to the rule as to how GPO’s apply to objects. As you can see in the image below the “Minimum password length” in the “Domain Password Policy” GPO is still applied to the domain controller even though I have another GPO linking to the “Domain Controllers” OU configuration the same setting.

image

For a better explanation as to why the GPO that is linked to the Domain and not the Domain Controllers is used for the password policy for all users check out Jorge’s Quest for Knowledge! – Why GPOs with Password and Account Lockout Policy Settings must be linked to the AD domain object to be affective on AD domain user accounts

 

How to set a Fine Grain Password Policy

Fine Grain Password Policies (FGPP) were introduced as a new feature of Windows Server 2008. Before this the only way to have different password polices for the users in your environment was to have separate domains… OUCH!

Pre-Requisites/Restrictions

You domain must be Windows Server 2008 Native Mode, this means ALL of your domain controllers must be running Windows Server 2008 or later. You can check this by selection the “Raise domain functional level” on the top of the domain in Active Directory Users and Computers.

image

Reference

AD DS: Fine-Grained Password Policies

The domain functional level must be Windows Server 2008.

The other restriction with this option is that you can only apply FGPP to users object or users in global security groups (not computers).

Reference

AD DS: Fine-Grained Password Policies

Fine-grained password policies apply only to user objects … and global security groups.

TIP: If you setup an “Automatic Shadow Group” you can apply these password policies to users automatically to any users located in an OU.

Creating a Password Setting Object (PSO)

Step 1. Under Administrator Tools Open ADSI Edit and connect it to a domain and domain controller you want to setup the new password policy.

image

Note: If you do not see this option go to “Turn Windows Features On or Off” and make sure the “AD DS and AD LDS Tools” are installed. (You will need RSAT also installed if you are on Windows 7).\

Step 2. Double click on the “CN=DomainName” then double click on “CN=System” and then double click on “CN=Password Settings Container”.

image

Step 3. Right click on “CN=Password Settings Container” and then click on “New” then “Object…”

image

 

Step 4. Click on “Next”

image

Step 5. Type the name of the PSO in the “Value” field and then click “Next”

image

Note: With the exception of the password length the following values are all the same as the default values in the “Default Domain Policy”.

Step 6. Type in a number that will be the Precedence for this Password Policy then click “Next”.

Note: This is used if a users has multiple Password Settings Object (PSO) applied to them.

image

Step  7. Type “FALSE” in the value field and click “Next”

Note: You should almost never use “TRUE” for this setting.

image

Step 8. Type “24” in the “Value” field and click “Next”

image

Step 9. Type “TRUE” in the “Value” field and click “Next”

image

Step 10. Type “5” in the “Value” field and click “Next”

image

Step 11. Type “1:00:00:00” in the “Value” field and click “Next”

image

Step 12. Type “42:00:00:00” in the “Value” field and click “Next”

image

Step 13. Type “10” in the “Value” field and click “Next”

image

Step 14. Type “0:00:30:00” field and click “Next”

image

Step 15. Type “0:00:33:00” in the “Value” field and click “Next”

image

Step 16. Click “Finish”

image

You have now created the Password Settings Object (PSO) and you can close the ADSIEdit tool.

Now to apply the PSO to a users or group…

Step 17.  Open Active Directory Users and Computers and navigate to “System  > Password Settings Container”

Note: Advanced Mode needs to be enabled.

image

Step 18. Double click on the PSO you created then click on the “Attribute Editor” tab and then select the “msDS-PSOAppliedTo” attribute and click “Edit”

image

Step 19. Click “Add Windows Accounts….” button.

image

Step 20. Select the user or group you want to apply this PSO and click “OK”

image

Step 21. Click “OK”

image

Step 22. Click “OK”

image

And your are done…  (told you it was hard).

Fine Grain Password Policies as you can see are very difficult to setup and manage so it is probably best you use them sparingly in your organisation… But if you really have to have a simple password or extra complicated password then at least it give you away to do this without having to spin up another domain.

How to use Group Policy to deny executing, writing and/or reading on removable disks


Removable memory sticks are the back door for data in any organisation. BitLocker to Go can do some way to controlling this vector however you might want to simple close off all access to removable drives for all your users. So if you are running Windows 7 you will be glad to know there are a heap of Windows 7 GPO setting that allows you to control access to your removable devices.

Even better there is a deny execute access policy setting prevents your users the running on BYO applications such as Firefox Portable and even some malicious software via USB sticks.

image

While most of the device types seem obvious, the WPD Device allows you to control access “to removable disks, which may include media players, cellular phones, auxiliary displays, and CE devices.”.

You can even configure the “Time (in seconds) to force reboot” which will enforce the change once it is applied to the computer.

These policy setting can be found under Computer Configuration > Policies > Administrative Templates > System > Removable Storage Access.

Its the best thing to control access to USB storage device since the invention of the hot glue gun….

Fine Grained Password Policy In The Win 2008/R2


Windows 2003 and below supports only single password policy in the domain and it wasn’t possible to configure multiple or different password or account lockout policy for the different set of users or groups within the same domain. The different password policy sometimes force to create different domain if you are hosting AD for the multiple clients due to their requirements. Windows 2008/R2 supports multiple password policy in the domain, which was most requested features in the newest OS. Microsoft heard it & introduced the different password policy in windows 2008 & above called as Fine Grained Password Policy(FGPP).

The requirement for implementing the Fine Grained Password Policy(FGPP) is domain functional level required to be windows at 2008 & above. This means your all the DC in the particular domain where you want to implement FGPP should be running DC’s in windows 2008 & above.

Windows Time Server Role In Active Directory Forest/Domain


I have seen various queries related with the windows time service configuration in Active Directory forest and domain architecture, so I decided to pen down an article which might be helpful to answer the queries. Foremost, let’s try to understand what is the time server role, how it works and why it is important to configured it right in the Active Directory forest/domain and issues faced if it is not configured or assigned to the right DC.

Time server’s role is assigned to the DC holding PDC role in the domain. Considering a different scenario where multiple domains exists in the same forest, how would you assign the time server role and which domain DC should be synchronizing the time server role either from the external or reliable source?

To answer the above: By default, there is only one PDC Emulator in each and every domain. The reason to assign time server role to only DC holding PDC role is DC with FSMO role acts like king of the kingdom which has ability to authorize the changes for resolving or avoiding conflicts. When new objects are created or existing objects are modified in AD (Active Directory), it is first being validated by the PDC FSMO role holder DC and post authorization it is allowed to replicate to all other DC’s in the forest/domain. User login to the domain, Kerberos ticket assignment,  AD/DNS replication, Creation/Change/modification in AD etc. are all dependent on time service sync with the PDC. If, there is any time mismatch of time between the DC’s in the domain, then authentication will fail, changes will not be replicated to other DC’s, resource access will fail and you could face several other issues. By default, domain allows time skew of 5 min, which means systems in the domain including DC can have time difference of 5 min but not more or less. In that case, users will not be able to login to the domain joined systems and will get authentication fail error messages.

If  there is single domain in the forest, then its easy to configure the time server role on the PDCEmulator. Considering the different scenarios, where multiple domain environments like Parent-Child or Tree-Root domains architecture are involved, in that case configure a DC with PDC FSMO role in the Parent/Root domain to be the time server role which is syncing its time from the external or reliable source and let all other domain to follow the Parent/Root DC time hierarchy. By default, DC holding the PDC role syncs its time from the reliable/external source and all other domain joined clients follow the PDC FSMO role holder DC to sync their time. The protocol used by the time server is NTP/SNTP.

In some cases, you might have to completely reset the time service, due to messed up time service registry keys settings which can be on the DC or member machine. The simplest fix is to un-register the time service on the problem domain joined machine(can be dc or member machine) and re-register it using below cmd. It worked for me most of the time and it might work for you too.

– Type CMD in the run windows

–  Type Net stop w32time to stop the time service

–  Type W32tm /unregister to unregister the time service registry

–  Type W32tm /register to register the time service registry back

–  Type Net start w32time

Configure the Windows Time service on the PDC emulator in the Forest Root Domain

You are required to run cmd given below on the DC holding the PDCEmulator role in the forest to sync the time from the external or reliable source. If its Tree-Root or Parent-Child domain then allow only the Root/Parent DC to sync its time from the external or reliable source and other domain(tree or child domain) should follow the time from the Root/Parent PDC hierarchy. External source can be internet and reliable source can be router or hardware clock.

Change the Windows Time service configuration on the previous PDC emulator or the domain client machines

Run the below cmd to reconfigure the DC previously holding the PDC role to sync the time from the new DC holding the PDC Emulator role, post moving the PDC role to the new DC. The below command can be used on any domain member client/server machine to reconfigure the time services to follow domain hierarchy.

w32tm /config /syncfromflags:domhier /reliable:no /update

You need to stop and start the time service using services.msc console or simply run this net stop w32time && netstart w32time on the cmd prompt.
