Question about Computers & Internet

On startup, i get the message: Isass.exe - Access Denied

A process has requested access to an object, but has not been granted those access rights.

If I click OK or simply close the dialog box, the computer will try to re-start but post the same dialog box over and over, not allowing my computer to load windows.

    I only have one floppy disc drive in my laptop, so can I do the following instead:

    1. Copy a good lsass.exe into a USB?

    2. Plugin the USB in my laptop and also insert Windows XP in my floppy disc drive.

    3. Startup my laptop and run it through SETUP

    4. Select REPAIR, enter admin password to bring me to DOS Prompt

    5. Copy Windows XP to C;\Windows\system32

    6. Enter EXIT

    7. Restart the laptop

    Kindly confirm if this is the way to go. Thanks.

    after REPAIR, I got to the DOS PROMPT --- C:\WINDOWS>

    When I tried copying Windows XP to C:\WINDOWS\SYSTEM32

    1. I went to D drive where my Windows XP installation disc is

    2. type: copy c:\windows\system 32

    message appeared: copy does not support wildcards or directory copies

    What should I do?

Looks like the windows login authentication having a problem authenticate your login.
go to "safe mode with network connection" and check the laptop for virus. go to Trendmicro and get the house call (online virus scan).
option is copy a good lsass.exe from another laptop or desktop pc and replace it.

"lsass.exe" is the Local Security Authentication Server. It verifies the validity of user logons to your PC/Server. It generates the process responsible for authenticating users for the Winlogon service. This process is performed by using authentication packages such as the default Msgina.dll. If authentication is successful, Lsass generates the user's access token, which is used to launch the initial shell. Other processes that the user initiates inherit this token. More info
Note: The lsass.exe file is located in the folder C:\Windows\System32. In other cases, lsass.exe is a virus, spyware, trojan or worm!

    OK

    here is something you can do.

    if you have the Windows Xp CD, that will be good.

    (NOTE: Following porcedure are in DOS format. everything are done via keyboard, mouse is disabled).

    First, copy a good "lsass.exe" from a working PC. put it on a floppy disk (if you still have one), if not, then you need to get an external one using USB. plugin the laptop, then startup the laptop. (do not connect USB after the laptop is up, it will see the usb.)

    second, if you are using the external floppy, you need to connect it first before turn on the laptop.

    startup the laptop with the Windows XP, let it run through the setup, till it ask you to "install Windows XP or Repair". select repair, enter local administor password. this will bring you to DOS prompt. you will have access to all of the drives. copy the file from Floppy to C:\windows\system32

    enter exit, and restart the laptop. you should be able to gain access to the operting system.

    I don't think the USB will work, but if it works that is great.

    you have copy the full path:

    ex: copy a:\lsass.exe c:\windows\system32\lsass.exe

    that is only way it will work. Windows Xp DOS is not the same as DOS 6.22 (last full DOS version).



    good luck! you almost there!

Information on lsass.exe - http://www.neuber.com/taskmanager/process/lsass.exe.html

Are you running a firewall (such as zonealarm)? It might be your firewall may be blocking a legit attempt by lsass.exe to run. You may have to add this to your firewall's allowed list. Of course if you are not running a firewall or if your firewall is already set to allow lsass you may have even greater problems.

Sounds like a corrupt system file. Try repairing using the Windows disk for the laptop. If that doesn't work, you will likely have to reinstall Windows.

When i try to install a critical update it was denied access by 7 zip. even after uninstalling 7 zip and installing winzip i still get the same response when trying to install updates 7 zip access denied....


Install Winrar, Here is the link

http://www.rarlab.com/rar/wrar391.exe

if you double click the file,the files will be extracted in the temp folder,so after installing winrar,right click on the file and select extract here. and try to install the update now,

Sometime when you extract files and it contains Malware or Trojan,Anti-Virus which support real time scan just block the files and the access denied message is displayed.

Scan the extracted files before installing so that you know it's Virus free.

Sometimes,even if you have administrator right,sometimes due to malware infection, you are denied access to some system hidden giles like folder under Local settings.
