Show Active Directory Group Membership

Sometimes it could be handy to save all members of an AD group to a text file.
This simple script will display all members of an Active Directory group on screen and mail the result to the logged in user (user@domain.com) if desired.

Copy Active Directory user group membership

powershell

Sometimes when a new user is added to a team he or she needs all, or a selection of the Active Directory groups his colleagues are member of. Unfortunately, this can’t be done with the native Active Directory tools. To overcome this, I made a Powershell script to (selectively) copy Active Directory user group membership from one user to another.

Monitor File Cluster Resources

powershell

When a (file) cluster resource failover occurred it is not always desirable to do an automatic failback (you probably would investigate the reason for the failover before performing a failback of the resources). Because of this I have created a Powershell script for use with file clusters to monitor file cluster resources, it works pretty much like the Powershell script I made for monitoring Exchange Database failovers (https://netflex.nl/exchange-database-activation-preference ).

The Powershell script monitors the preferred owner of a resource. In the event the Powershell script detects a resource is not running on the preferred owner, the Powershell script will send an email alert to a predefined recipient.

Access is denied at domain controller login

domain-controller

Issue

Today I came across a weird issue. When logging on to a Domain Controller (2008 R2) I was presented an ‘Access is denied’ error. Weirdly enough this happened after the authentication took place.

There were no related events to be found in the event viewer. Looking at the domain controller policies and running tools like dcdiag/nltest (using psexec) didn’t provide any clues either.

Exchange Database Activation Preference

powershell

An Exchange database availability group (DAG) provides fault tolerance for your mail databases. When a mailbox server fails or when doing maintenance your users will still be able to send mail.  Unfortunately you don’t always know when a failover took place. This could be because no monitoring is in place. The moment you realize some databases failed over is properly when users are complaining of a slow mail system.
