    A little while back my computer would boot up to the xp logo screen then I would get an error LSASS.exe Endpoint format invalid error message.
    Then it would restart itself,system restore wouldnt work(even to a long time back).
    I could start Windows in safe mode though.
    As it happened I was About ready to reformat the machine back to original condition anyway.
    But to prevent it happening again I was wondering what the Hell happened.
    Any Ideas or similar problems?

    you need to know what the heck LASS.exe is.
    it's not a windows file...back the damn file up..ok go to the safe mode and then delete it...search for the file and right click and see its properties..maybe it's a virus.
    don't forget to back it up before delete it.
    you windows works good in the safe mode because that file is a 3d party.

    LSASS.EXE is the Local Security Authority Sub-System. Essentially, it's the file that gives you Windows NT, 2000, and XP. If it can't start you can't get in. Try to boot to the XP CD, run Setup, and choose the repair option. If that doesn't work, install Windows XP over itself. You shouldn't lose any data, but who knows..... If that also fails, all you can do is reformat and reinstall the OS.

    Thanks Kr0m I found that site after I re-installed (Only had the factory restore option for xp).
    Need to keep my backup comp at home and put xp on it, Instead of the wonderful win2000(Sarcasm).
