When preparing for a migration of AD objects from one forest to another it is useful to know if any of the names are going to conflict.

Something I often recommend to my customers is keep the membership of the Enterprise Admins and Schema Admins groups empty and only populate them (temporarily) when required.

Here’s a quick Powershell snippet that will… Read More: How to clear group membership with Powershell »
Many organisations choose to rename the Built-in Administrator account for the domain for security reasons.

Many moons ago I provided a CSV file containing 200 sample AD user accounts together with instructions on how to use CSVDE to import the accounts into AD. I often use these sample accounts in lab environments and for presentations. I thought it would be fun to write a small powershell script to read the… Read More: Bulk create sample AD users from CSV file using Powershell »

I was recently involved in a task to consolidate an OU structure. Part of this involved moving user objects from one OU to another and re-linking GPOs that were linked to the old OU to the new OU. There were a large number of links and I didn’t fancy adding them manually, so I spent… Read More: Powershell script to Copy GPO Links »
After my Teched break-out session yesterday I was asked if I could share the PS command dictionary file that I used to support my demos. Here it is (right-click Save Target As): CommandDictionary.psd1 For those of you that weren’t there the PS commands mostly relate to working with the AD Recycle Bin feature of Windows… Read More: Teched 2010 New Zealand – Powershell command dictionary file »
