Show Active Directory Group Membership

powershell

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.

Turn off ADFS for o365 when ADFS servers are not reachable.

office365

When there is a problem with your ADFS server(s) or your internet connection, there is no authentication possible on ADFS. Users are not able to login to their mail, use Skype For Business or Sharepoint.

When this happens, it is good to know there is an easy way to turn federation off and on again in powershell without requiring a connection to the ADFS server.

Before you start, make sure you had password sync enabled on the AAD Connect server. If not, you will have to set a new password for every user after disabling federation. Continue Reading

Synchronize Mail and Calendar-items of a GroupWise Resource to your mobile device.

Within GroupWise Mobility Service 2.x it is possible to synchronize GroupWise resources to your Mobile device. This makes it possible for users to sync a resource where they have proxy-access.

 How does it work?

Create a new or use an existing resource. Proxy to the (new) resource and give it a password via the settings in the GroupWise client. By proxying once to the resource, the contact folders will be created which makes sure the account can be synchronized correctly by the GMS server. Continue Reading
