Failover Cluster – An error was encountered while loading the network topology

Sharing and friendly reminder for myself as I will for sure run into this problem again in the future.

When creating a Windows Failover Cluster, you get this error message (btw, did you know you can Ctrl+C copy the text from a dialog box and paste like this);

 

Solution: In this case I had to remove the User Account from AD’s “Protected Users” group because Failover Cluster is still using NTLM and CredSSP. Relogon and it’s now possible to create the cluster, and then just add the user back into the Protected Users Group.

Update AD-Users with new Phone-number and Pager via Powershell

Had a quick question from a customer about how one can automatically update the phone number and pager of a lot of AD users. The customer was changing switchboard and had to add 1 number in front of the current number.  Adding it in the middle of the string is also possible, but slightly more complicated as you have to split the string.

This is possible to do in a few different ways, but I chose the quickest way for me, via Powershell.

End Result:
