Removing an Adfs Server

Removing an Adfs Server from the MFA farm doesn’t remove the server from Adfs farm 😃.

Server is removed from MFA servers list. So, no notification can occur, and some commands will not operate. You can use this command if you only want to remove a server from your farm

  • Launch a new PowerShell session as administrator
  • type get-help UnRegister-MFAComputer –detailed to get information.
  • Enter your command
UnRegister-MFAComputer -ServerName yourserver

Notifications are used to sync configuration changes without restarting ADFS instances. for example, if you change the password in SMTP configuration, this modification is “live” updated on all servers in the MFA list.
