Re: DNSAPI.DLL file is missing

[LAKESUSY]

I am starting my own topic.......again...sorry
I have been trying to help my sister with her messed up computer. She is running XP.  On start up, the screen goes to the windows logo, acts like it is trying to boot up but eventually comes up a blank screen with the error message that the DNSAPI.DLL file is missing. This error message is contained in a dialogue box titled lSASS.EXE. I have tried holding the F1, the F8 and the F12 keys to get to a safe mode option or boot to disk but these keys are not recognized. It ends up on a blank black screen. Is there anything I can do?

lSASS.EXE - is the first letter capital "i", or capital "l""?
LSASS.EXE is a legit file, but ISASS.EXE is a malware.

I believe that it is a lower case L. This is my sister's computer I was trying to fix and I am home now so I can't check. When I wrote it down I wrote it as a lower case L.  She said that she was trying to install an update that she had been prompted to download. She is even less computer literate than I am so she's not very helpful. In the middle of the download she turned off her computer.

IF it's lower case "L", then...

I have tried holding the F1, the F8 and the F12 keys to get to a safe mode option or boot to disk but these keys are not recognized.

To access Safe Mode, you have to keep TAPPING F8 key, as soon, as computer starts.
If you can get into Safe Mode, try System Restore.
If you can get into Safe Mode, and System Restore doesn't work, go Start>Run, and type:
sfc /scannow
Click OK.
Have Windows XP handy.
If yoy can't access Safe Mode, boot from Windows CD, and run repair: http://www.michaelstevenstech.com/XPrepairinstall.htm

Thanks. I will see if I can get my sister to try above.
The computer is a Dell and is/was running XP.
