 | A mate was visiting sites he shouldn't have and probably downloaded some software without knowing it. So now when he boots, the bios runs fine, widows xp start page loads then an error window opens regarding lsass passwords, window closes after about 5 secs then pc reboots. I got into safe mode but when it restarts in safe mode the same error msg comes up and then reboots. He has no hard copy of win xp, as its on the hard disc, and I can't seem to get into dos to check out the dir. Any clues, Thanks. Peter.

Sounds like a variant of the Sasser worm http://securityresponse.symantec.com/avcenter/venc/data/w32.sasser.worm.html Should be able to find a cure easily enough.

Windows xp does not use dos.
Boot from a setup CD - any XP CD, and then choose recovery console - this should get you to a command prompt if you need one.
You could also try repairing the installation
another option is to make a BartsPE CD and then boot the system off that then run one of the supported Virus scanners or adaware etc to check the system out and then run XP setup repair.

Firstly, this is NOT the SASSER worm as per Mr Scebe's reply - that is a red herring (the SASSER worm effects LSASS, but with different symptoms).
The problem you are having is usually caused by a corrupted password file.
Firstly, have you tried "Last Known Good Configuration"? This might replace the corrupt password file, and resolve your problem.
Secondly, when you logged in to Safe Mode, which user did you use? If it was the standard user account, try using "Administrator" (try with no password if you are unsure what the password is).
Post again with a reply to the above, and I'll try to get it sorted for you.

Oh, and the other thing is to try simply doing a system restore from the command line.

Is it "When trying to update a password the return status indicates that the value provided as the current password is not correct."?
Are you using XP Home or XP Pro?
Also, have you tried FIXBOOT and FIXMBR from the recovery console?

No worries.
It is not the Blaster worm (the symptoms are similar, but different).
Other thing to try is to remove the hard drive, pop it in a different computer, backup the files in x:/Windows/System32/config, then overwrite them with those in x:/Windows/repair (x being their drive).
You'll need to do it from another machine, as the security files will not be able to be overwritten whilst the machine is running. (Alternatively, you could use a BartsPE or Knoppix CD).
Let us know how you get on.
