  • Codeplex AD Replication Module

    The other codeplex project that caught my eye was a brand new one to create a PowerShell module to manage AD replication.  This one will be very useful and one I will be using a lot. There is still time for suggestions as to content for this project – see http://adreplicationmodule.codeplex.com...

  • AD attributes

    I had a question come through as a private message regarding how to extract a particular attribute for user objects. The script wasn’t working because the label name in AD Users and Computers didn’t match the attribute name. This is a fairly common scenario as there are quite a few attributes like this...

  • Select-String

    One task I had to do a a few times recently is track down which GPOs had a particular setting enabled. If you are working in an environment with a signifcant number of GPOs this can be a tedious task. The easier way - use the SDMSoftware GPMC cmdlets to create an XML file for each GPO. You can then use...

  • Windows 2008 R2 - OU

    One of the big benefits of Windows 2008 R2 is the fact that PowerShell v2 is installed by default and that AD can be administered by PowerShell. There are 76 AD cmdlets and an AD provider. We’ll start by looking at the cmdlets. Organizational Units are the subdivisions with a domain. We can easily create...

  • Active Directory Cookbook third edition

    The original AD cookbook by Robbie Allen was published back in 2003. It has been one of my favourite, and most referenced, books. When I used to use VBScript (shudder) it was indispensible and saved me vast amounts of time. One AD implementation I did we created the whole AD structure – OUs, Sites, Subnets...

  • Quest AD cmdlets

    If you have followed this blog over any period of time you will know that I am a big fan of the Quest AD cmdlets. The good news is that version 1.2 of the cmlets has gone RTM. The bad news is that it won’t be available for a little while yet. The major details of the changes are available from http:...

    Chapter 10 is now available as part of the MEAP - http://www.manning.com/siddaway/ This one deals with the structure of Active Directory.

  • S.DS.AD - SiteLinks

    SiteLinks are used to control replication between Active Directory Sites. We have already seen how to find the current site and how to view the domain controllers in that site. How do we know what sites our site is replicating with – follow the sitelinks. $site = [System.DirectoryServices.ActiveDirectory...

  • S.DS.AD - sites

    Sites are the foundation of the physical topology of Active Directory. While there has been a lot posted about working with users and groups i.e. the data in Active Directory there hasn’t been as much posted about working with the physical structure.

  • S.DS.AD – netlogon service 2

    Last time I said that I wanted to improve the way the data was displayed when we interrogated the netlogon service on our domain controllers. One way we could do it is to use Add-Member to add the data to an object $a = @() $type = [System.DirectoryServices.ActiveDirectory.DirectoryContextType]::Domain...

  • S.DS.AD - Domain

    We looked at AD Forests last time – moving along we come to domains. We can discover the current domain in a similar manner to the forest $dom = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain() $dom The standard output includes Forest : Manticore.org DomainControllers : {CSDC1.Manticore...

  • S.DS.AD - Forest

    System.DirectoryServices.ActiveDirectory – its a bit of a mouthful so I’m going to abbreviate it to S.SD.AD – is a .NET namespace that works with Active Directory. Unlike System.DirectoryServices it is not an ADSI wrapper but works through non-LDAP protocols to access AD. It is designed for administering...
