Problem:
The audited sessions are listed on the Audit Analyzer as usual. After selected an audited session and clicked “Replay”, the session player shows up with a blank screen. Then the session player becomes unresponsive and it consumes lots of CPU resource.

Possible Cause:
One of the possible cause is corrupted font cache due to faulty video driver causing WPF application to hang.

Suggested Solution:
Please try the following steps to clean up the WPF font cache on the problem machine and see if the issue occurs again:

1. Make sure the current user has local administrative privilege
2. From the start menu search bar, type services.an and launch it
3. Find "Windows Presentation Foundation Font Cache 3.0.0.0" (FR: "Cache de police de Windows Presentation Foundation 3.0.0.0") and stop it
4. Go to C:\Windows\ServiceProfiles\LocalService\AppData\Local, delete FontCache3.0.0.0.dat
5. Restart the machine

In case the issue still persists after applied above workaround, please contact Centrify Support for further assistance.
