I quite regularly come across Active Directory environments where users have been mistakenly added to groups protected by the AdminSDHolder and subsequently removed when the mistake has been realised. This process creates “orphans” because the AdminSDHolder process doesn’t tidy up after itself. Here’s what happens: User added to group protected by the AdminSDHolder (e.g. Account… Read More: Cleaning up AdminSDHolder orphans »
Back in March 2010 when Powershell and I were on somewhat less friendly terms, I wrote an OU shadow script to populate group membership based on the contents of an OU. Since then, Powershell and I now at least acknowledge eachother when we pass in the corridor and I have updated the script with some… Read More: OU Shadow Script »
Occasionally, I have a need to merge the attributes of one AD user into another. This requirement is typically the result of a migration where some users have had accounts informally created in the target environment in advance of the formal migration process.

If you’re familiar with LDAP searches you will probably at some point have been frustrated at the inability to exclude objects in a specific Organisational Unit, i.e “Give me all User objects in the domain, except those in the Sales OU”. To workaround the problem you typically need to do some scripting. There are several… Read More: Powershell search for Active Directory objects excluding an OU »
If you come across this error when using Powershell to delete an object, it is most likely because the object has child objects associated with it. The most obvious example is computer objects that have print queue, service connection point, RRAS or various other types of child objects. The workaround is to determine the child… Read More: The directory service can perform the requested operation only on… »
Recently I was doing some testing with a new Exchange 2010 Receive Connector and wanted a method to check how many messages it was processing. I came up with the following Powershell snippet that seems to work well. $i = 0 do { $now = get-date (Get-MessageTrackingLog -ResultSize unlimited -Start “11/10/2012 3:00PM” -End $now -Server… Read More: Powershell: Counting messages processed by a Receive Connector »
