ADFS Server Updatepassword 407 Error

Brass Contributor

Hi fellow tech community participants,


I have an ADFS Server (Windows Server 2016) which has recently started to throw errors when trying to use to change a user password.


The user is getting a message like "user id or password is incorrect even though the username and password are correct.


In the Eventlog of the ADFS I can see a 407 Error with the following content:

Password change failed for following user:

Additional Data


Server on which password change was attempted:

Error details:


What bothers me the most is that there seems to be no server on whicht the change was attempted.


Using nltest I get the following output:

C:\Windows\system32>nltest / /pdc
Getting DC name failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN


I can ping the PDC just fine and I can see that it tried using that server 3 days ago when someone entered a wrong password in the change password dialog.


Does anyone know how to resolve this?
