Hello,
I have an issue with dpapimig (and with CryptUpdateProtectedState) when I try to migrate a master keys from a Window server 2019 to another Windows server 2019.

dpapimig says that password is not correct and the api CryptUpdateProtectedState return True with pdwSuccessCount=0 and pdwFailureCount=1.
I'm using local user.

If I do the operation on the same Windows Server 2019 (after having removed the user and created a new one). Everything works properly.
With Windows server 2016, Windows server 2012r2, everything works properly also.

Reproduction steps:

• On Windows server 2019 #1, create a user test
• Create a session with this user
• Keep the directory %userprofile%\AppData\Roaming\Microsoft\Protect\<sid>
• On Windows server 2019 #2, create a user test
• Follow steps from ee681624(v=ws.10)

Actual Result

• password issue

  Expected result

• master keys imported without issue

Thank you for your help,

David

Hi,

I made more tests on a fully updated Windows. The migration issue with dpapimig still exists.

I notices some points:

• The issue seems to be related to lsass. (according to procmon)
• The migration works when the 2 computers SID are the same. After a sysprep, a working Windows server is not able to do migration. When I restore the computer SID using sidchg (https://www.stratesave.com/html/sidchg.html), The migration works again.

The tool dpapimig and the API CryptUpdateProtectedState are still supported ?

Best regards,
David.

Hi,

I tried again on a fully updated Windows server 2019, the issue still occurs.

But, I noticed that this issue does not exist on a fresh Windows Server 2019 not updated.

So this issue is probably caused by a KB deployed after the installation.
The only KB which seems to be related with dpapi is KB4517211.

Best regards,
David.

Hi,

Thank you for your help.

I have already see this link but it does not help me.

As I said, it was working before Windows server 2019: It works properly with Windows server 2012 and Windows server 2016.

Best regards,

David.
