When this issue occurs, the user's current password does not match the password that is cached in Credential Manager. This issue can occur immediately after the user or an administrator performs a password change. It can also occur after some time has passed after the password change.
The following configurations are known to contribute to this issue:
- The user has a mapped home folder to a Distributed File System (DFS) path, such as \\contoso.com\homefolders\user.
- The user has enabled the "Set a default associations configuration file" Group Policy Object for file association sets. Also, the XML is stored in a DFS path, such as \\contoso.com\netlogon.
- The user has GPP for Drive Maps that map a folder in a DFS path, such as \\contoso.com\data1.
CauseThis issue occurs because of a deadlock between Credential Manager and the Redirector (RDR) and Data Protection API (DPAPI).
