Credential manager issues (0x80090345) After Windows updates 24H2. Hybrid device environment.

Hey Guys,

Environment:

Domain controller in combination with Hybrid joined devices.

Domain joined / Intune managed.

Windows Hello in use.

Problem:

Issues with login in to software for remote workers (Outlook, Essentials app, Adobe ect.)

Issues with opening Credential manager (error: 0x80090345)

Cause:

Problems started after 24H2 update.

Troubleshooting taken:

Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb Value: ProtectionPolicy Value Type: DWORD Value Data: 1Regkey has been set, this solves the problem but can introduce other problems down the line.

When the user logs in with domain credentials (not line of sight with DC) it works. With Windows Hello it doesn't work. Windows Hello is already working for years and does still work at the office (line of sight with DC.)

Seems to be something related to the DPAPI Masterkey, wich should make a local backup on the machine when first logon in the DC network. But when users are at home it works for a moment and then get the same issue.

Any of you that have similar issues or have something i can look in to?
