Hello, Does anyone know of a way to fix this error: LSASS.EXE System Error Security Accounts Manager initialization failed because of the following error: The Security ID structure is invalid. Error status 0xc0000078. I've looked all over the internet, and have tried my own troubleshooting techniques. Nothing is working. Once I hit the OK button on this error, it automatically reboots. Can anyone help? Thanks!
