Hello everyone,
In recent days, some computers in my domain are giving me the following error at startup and "freezes" in the future. I am Unable to "log" or do anything on the computer.
"Winlogon.exe"
"This application has failed to start because sfc_os.dll is found. Reinstalling the application may fix this problem."
- Unable to log windows in normal mode or in Safe Mode
- Sfc_os.dll is already present in c: \ windows \ system32 \
- They are all on windows XP service pack 2
After several searches, I tried some solutions but nothing seems to work long term.
First, replaced sfc_os.dll in c: \ windows \ system32 \
-> Does not work
Second, choose "last good configuration" at startup of windows.
-> Only works for about 1 or 2 days ...
The only way to solve the problem seems to reinstall Windows. (I use RIS (Remote Installation / Windows Deployment Service) + GPO)
My question is:
- Is it a file other than sfc_os.dll which is causing this problem?
- What are the causes of this problem?
- Is this a virus?
Thank you for your help!
