What is the Lsass.exe process?
Lsass.exe is a system process that is used for local security authentication servers, and she generates a process for user authentication of the Winlogon service. If authentication succeeds, LSASS generates an access token for the user to start the initial shell. Other processes initiated by the user will inherit this token.
Can lsass.exe be a virus?
Lsass.exe files are generally located in the C:windowssystem32 directory. If Lsass.exe appears elsewhere, then she could be a virus, Trojan horse or malicious program! Common virus names are w32.sasser.e.worm (Lsasss.exe), W32. Nimos.worm and so on.
Why prompted Lsass.exe system errors
One, virtual memory is not enough
Common hints are: "Lsass.exe system error: Insufficient system resources to complete API". This happens, generally due to the lack of virtual memory, then we can use the boot CD, such as WinPE, and so on, into my Computer-properties-Advanced-Performance tab, set virtual memory for the disk space outside the system is larger partition-determine-reboot the computer can be normal access to the system. When setting up virtual memory, it is generally recommended that virtual memory be set to 1.5~2 times the physical memory capacity (the minimum and maximum values for virtual memory, respectively).
Two, careless mistake operation
It is common to try to change the password, to provide an incorrect password, or to corrupt the SAM file (no extension) located in the "C:windowssystem32config" directory. This time we still use the boot CD, the "C:windowsrepair" directory to replace the SAM file to the above path.
Third, the virus reason, the related dependent file loss
The
Common hints are: "Lsass.exe cannot find the entry: Unable to locate the program input point asn1ztcharstring_free on the dynamic link library Msasn1.dll", "Lsass.exe cannot find the component: Dnsapi.dll not Found", As to which DLL is missing, depending on the situation.
