I got home from a hard days work and went to boot up the ol puter and after the XP splash screen I get an error reading "lsass.exe failed to load, could not find the fild dnsapi.dll....reinstallation of this will fix problem"

What do I do? I tried a repair with the windows installation cd but it says I don't have any hard drives installed!
Also tried to copy this dnsapi.dll file from a dos boot but it couldn't find the c:\!
If my computer says it can't find HD...but it's getting past the XP splash screen...I'm so perplexed.
Please Help!

I think you may have a virus on your PC...here...........what antivirus do you use??

Norton 2003 updated definitions.

Any idea how I would be able to scan for one without being able to get into windows? Safe mode doesn't work either.

Have you got the latest updates from M$ ?

Probably.
Shouldn't matter much in this case though.
I just tried booting off of a regular IDE hard drive but couldn't get it to boot and recognize the problematic ATA hard drive.
I don't know what to do.

the computer froze everytime after the winxp splash screen, so i tried doing some stuff to try and fix it but the BIOS isn't detecting that a HD is there, nor from a dos boot disk. but when i start up the raid controller prog... that detects it, so does a maxtor dos prog i downloaded onto a floppy and ran.......i tried running the winxp installation cd but it says that can't continue because theres no HDs installed.....even after i formatted the thing.......any ideas?!
