Error code 700003

Question

Recently, I face the issue i logged into my vdi and my vdi was stuck/hang so i opened the new vmware and first vdi was already open and second one was loading as authenticating and it open explorer for either password/username so immediately i closed the second vdi was authenticating when i came to close my explorer tab i saw this error

why i told my story recently i had one ticket by stating that user login multiple times she was having some authentications 50 times in 5 mins failed logon alert triggered so the cleint ask if alert is triggered due to multiple failed login this why error code was 700003 that the device is deleted from organization? I also similar face the same issue i got the same error

Answer 1

Error code AADSTS700003 means the device object was not found in the tenant directory. It is a device registration issue, not evidence by itself that repeated failed logons caused the error.

In this scenario, the repeated authentication attempts could be a symptom of a stale or broken device-bound sign-in state, but the documented meaning of 700003 is that the sign-in flow is referencing a device object that has been deleted or is no longer valid.

Supported recovery depends on the device join type:

1. Microsoft Entra registered device
   Go to Settings > Accounts > Access Work or School, disconnect the work or school account, then register the device again.
2. Microsoft Entra joined device
   Open an elevated PowerShell window and run:

      dsregcmd /forcerecovery
   

   Then sign in again.
3. Microsoft Entra hybrid joined device
   Open an elevated PowerShell window and run:

      dsregcmd /leave
   

   Then restart the device and sign in again with domain credentials.

If this happened during sign-in to a Microsoft Entra joined VM, also verify:

• the device used to connect is Microsoft Entra joined or hybrid joined to the same tenant as the session host
• PKU2U is enabled on both the local PC and the session host
• per-user MFA is disabled for the user account, because it isn’t supported for Microsoft Entra joined VMs

So, to the client’s question: no, 700003 does not mean “the user logged in multiple times.” The documented cause is a missing/deleted device object. Multiple failed authentications may happen around the same time, but they are not the defined meaning of this error.
