Identified
TDX # 7545 Beginning at 1:21 am ITS began to receive reports of Windows systems that were not communicating with the network. Upon investigation it has been determined that some Windows servers and Windows endpoints (desktops/laptops) running the CrowdStrike Falcon Sensor and also having a particular file installed would blue screen and loop.
CrowdStrike has provided the following manual fix and it has proven to work. PLEASE NOTE: Windows systems and endpoints with BitLocker encryption may need BitLocker recovery keys to access safe mode. Departmental support will need to be engaged to access these keys. ITS can assist departmental IT as needed.
