Single Sign-On fails to synchronise after Windows 10 Feature Update
Article ID: KB396 email a link to this article

Problem

You have Single Sign-On (SSO) enabled and are receiving Access Denied when trying to enter your password at the Pre-boot authentication login after changing your password within the user's Windows profile.

Please note that the previous password will still work.

Cause

During a Windows 10 feature update, a .dll file that relates to SSO fails to re-register itself correctly. 

Solution

Method 1 - This is the preferred method for fixing the problem.

Upgrade to ESET Endpoint Encryption version 5.0.1 or later and then follow the password recovery steps as before, and login to Windows manually to allow SSO to re-sync automatically.

See: KB203 - How to upgrade ESET Endpoint Encryption (managed)

Method 2

Alternatively, you can open an elevated command prompt and enter the following commands:

cd %ProgramFiles%\DESlock+ 

regsvr32 dlpwpflt.dll 

Once completed, a dialog box will appear confirming the .dll has been registered successfully.
