Cause research: Snipping Tool and other components in Windows 11 no longer usable due to expired certificate

Today went through many Mediathat some apps and components in the recently released Windows 11 no longer work since 01.11.2021 and that the cause for this is a certificate that expired on 31.10.2021. In the meantime Microsoft has pointed out in a blogpost and also a patch for some affected components published.

Unfortunately, none of the available sources provided detailed information about what exactly the problem was. So let's get to the bottom of this ourselves.

The database schema of the Certification Authority database

Would you like to Queries against the Certification Authority database formulate, you must first know what you want to look for.

There is a possibility to output the database schema of the certification authority database.

Limits of Microsoft Active Directory Certificate Services

Active Directory Certificate Services have existed (albeit under a different name) in their basic form since Windows NT 4.0. The Active Directory-based architecture used today was introduced with Windows 2000 Server. AD CS is very well integrated into the Windows ecosystem and continues to enjoy great popularity worldwide in companies and government agencies of all sizes.

People like to point out the many possibilities offered by Active Directory Certificate Services. Rarely, however, is reference made to what can be done with them. not is possible. In the meantime, the product has also reached its limits in many places.

What these are will be explained in more detail below in order to better decide whether the AD CS can be the right solution for planned projects.

Manual assignment of a Remote Desktop certificate fails with error message "Invalid parameter".

Assume the following scenario:

A Manually requested Remote Desktop certificate should be on a computer be assigned to the remote desktop session host.
The operation fails with the following error message:

Set-WMIInstance : Invalid parameter
 At line:1 char:1
 Set-WMIInstance -path $TerminalServicesConfig.__path -argument @{SSLC …
 ~~~~~~~~~~~~~~~~~ CategoryInfo          : InvalidOperation: (:) [Set-WmiInstance], ManagementException

When restoring a certification authority, the certification authority certificate is not selectable during role installation

Assume the following scenario:

A Certification Authority will migrated to another server or restored from backup.
A Thales (nCipher) hardware security module (HSM) is used to protect the private key of the certification authority certificate. Security World is configured with Operator Card Set (OCS) Protection.
The Certification Authority certificate was successfully restored and associated with the private key stored on the HSM..
When installing the certification authority role, the restored certification authority certificate cannot be selected.

Installation of a certificate authority certificate fails with error message "Object was not found. 0x80090011 (-2146893807 NTE_NOT_FOUND)".

Assume the following scenario:

A new certification authority is installed.
After configuring the certification authority role and issuing the certification authority certificate, it should now be installed on the certification authority.
A hardware security module (HSM) is used to protect the private key of the certification authority certificate.
The installation of the certificate authority certificate fails with the following error message:

An error was detected while configuring Active Directory Certificate Services.
The Active Directory Certificate Services Setup Wizard will need to be rerun to complete the configuration.
The new certificate public key does not match the current outstanding request.
The wrong request may have been used to generate the new certificate:  Object was not found. 0x80090011 (-2146893807 NTE_NOT_FOUND)

Reconnecting to the private key fails with error message "Cannot find object or property. 0x80092004 (-2146885628 CRYPT_E_NOT_FOUND)"

Assume the following scenario:

A Certification Authority will migrated to another server or restored from backup.
A hardware security module (HSM) is used to protect the private key of the certification authority certificate.
The certification authority certificate should now be installed on the target system. be restored and linked to the private key.
The operation fails with the following error message:

Cannot find the certificate and private key for decryption.
CertUtil: -repairstore command FAILED: 0x80092004 (-2146885628 CRYPT_E_NOT_FOUND)
CertUtil: Cannot find object or property.

Installation of the default certificate templates fails with error message "This security ID may not be assigned as the owner of this object."

Assume the following scenario:

For the first time, a certification authority (Enterprise Certification Authority) integrated into Active Directory is to be installed in the network.
The rights to install the certificate authority have been delegated to a separate security group or account for security reasons, so no Enterprise Administrator login is required. Put another way: The user used is not a member of the Enterprise Administrators group in the Active Directory forest.
Since this is the first certification authority in the network, no Standard certificate templates installed in the Active Directory. When opening the certificate template management console (certtmpl.msc), one is prompted to install it.
The installation fails with the following error message:

Windows could not install the new certificate templates. This security ID may not be assigned as the owner of this object.

Code signatures of Appx packages via SignTool.exe fail with error code 0x8007000b (ERROR_BAD_FORMAT)

Assume the following scenario:

An Appx package is to be signed.
For this purpose the SignTool.exe used.
The code signing certificate used was recently renewed.
The signing process with the new code signing certificate fails with the following error message:

"Error: SignerSign() failed." (-2147024885/0x8007000b)

Issue certificates with shortened validity period

Sometimes it is necessary to issue certificates with a shorter validity period than configured in the certificate template. Therefore, you may not want to reconfigure the certificate template right away or create another certificate template.

Root certificates are imported on domain members into the certificate store for intermediate certificate authorities

Some will have noticed that the certificate store for intermediate CAs usually also contains certificates for root CAs.

As a rule, this behavior is not critical. In certain cases however, this can also cause problems with applications.

Basics: The Key Usage Certificate Extension

Certificate extensions were introduced with version 3 of the X.509 standard. The Key Usage extension is an optional certificate extension that can be used in the RFC 5280 is defined and is used to limit the allowed uses for a key.

Establish a mapping from a user certificate to the associated computer

Assume the following scenario:

A user's computer is stolen or infected with malware.
The integrity of certificates located on the computer can no longer be guaranteed.
The certificates of the user(s) that were requested on this computer must be revoked.
However, one would like to avoid revoking all certificates of a user.
Thus, a connection must be established between the user's certificates and the computer on which they were requested.

If the certificates were issued by Autoenrollment requested, we can take advantage of the fact that a corresponding attribute was part of the original certificate request, and that the certificate request is stored in the certificate authority database along with the certificate.

No remote desktop logon possible from outside the Active Directory forest

Assume the following scenario:

You want to establish a remote desktop connection.
The client computer from which the connection is made is not a member of the same Active Directory forest as the target computer.
The connection fails with the following error message:

A user account restriction (for example, a time-of-day restriction) is preventing you from logging on. For assistance, contact your system administrator or technical support.

Login to the Network Device Enrollment Service (NDES) administration web page fails with HTTP error code 401 "Unauthorized: Access is denied due to invalid credentials."

Assume the following scenario:

An NDES server is configured on the network.
When calling the NDES administration web page (certsrv/mscep_admin) is not possible.
After several unsuccessful login attempts, the following HTTP error message is returned:

401 - Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied.
