Active Directory – A Geeks World

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);

[Window Title]

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.

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.

# Verify how it looks like before executing the script. 
# It's easy to add a Export-CSV at the end of this line to have a backup. 
Get-ADUser -SearchBase "OU=Test,DC=dreamhouse,DC=local" -Filter * -properties *| select Name, telephoneNumber, Pager 

# Add a "2" infront of Pager 
# Add a "8" infront of TelephoneNumber 
Get-ADUser -SearchBase "OU=Test,DC=dreamhouse,DC=local" -Filter * -properties * |            
 ForEach-Object {
 Set-ADObject -Identity $_.DistinguishedName -Replace @{Pager="2$($_.Pager)"}
 Set-ADObject -Identity $_.DistinguishedName -Replace @{telephoneNumber="8$($_.telephoneNumber)"}
 }     

# And Verify it went well. 
 Get-ADUser -SearchBase "OU=Test,DC=dreamhouse,DC=local" -Filter * -properties *| select Name, telephoneNumber, Pager

# Verify how it looks like before executing the script.

# It's easy to add a Export-CSV at the end of this line to have a backup.

Get-ADUser -SearchBase "OU=Test,DC=dreamhouse,DC=local" -Filter * -properties *| select Name, telephoneNumber, Pager

# Add a "2" infront of Pager

# Add a "8" infront of TelephoneNumber

Get-ADUser -SearchBase "OU=Test,DC=dreamhouse,DC=local" -Filter * -properties * |

ForEach-Object {

Set-ADObject -Identity $_.DistinguishedName -Replace @{Pager="2$($_.Pager)"}

Set-ADObject -Identity $_.DistinguishedName -Replace @{telephoneNumber="8$($_.telephoneNumber)"}

}

# And Verify it went well.

Get-ADUser -SearchBase "OU=Test,DC=dreamhouse,DC=local" -Filter * -properties *| select Name, telephoneNumber, Pager

End Result:
