Microsoft is just takin' credit for the work you've done 69Rat    "Oh, thats a good idea, why don't you download HJT, run it, then send the log........"   Leave it to Microsoft.......      It is good to be ahead of them, though 

Yeah, but by the same token, the process that is executing (possibly a virus or other errant action) may not like to be interrupted until it is done doing whatever it was written to do.......  Did you actually find the file with that funky name on your hd?

Haven't used the search feature too much with XP so I got this from here: http://www.cyberwalker.net/columns/aug03/find-file.html
You can just copy and paste the filename from here      9vs7sxtxnn585u.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll

*****************
 However here's the detailed search instructions for Windows XP owners. First click the START button (bottom left of your screen) then "Search", then select "For Files or Folders". A window will pop up with a details box on the left hand side that looks like this:
Search box from Windows XP

Next, click on the green arrow next to "All files and folders" unless you know specifically what type on file you have lost. If you have downloaded a picture, a music file or video or a document such as a Word file or PDF then click on the specific search option item that relates to that kind of file.

A new box will pop open. Next type in all or part of the filename in the top field that says: "All or part of the file name". If the file was called "paintprogram.zip" then type it in. If you don't remember, type in part of the name such as "paint". However the less specific you are, the more likely that you'll find all kinds of files like that that are already on your system. If the file was a document you could also type in a few words from the document (maybe you know the title or topic?) into the second box titled: "A word or phrase in the file".

Search Windows XP

Finally, in the "Look in:" field leave your "C drive" selected unless you know for certain that you downloaded the file to another computer drive. If you want to search the all the drives including CD drives and floppy drive (if you have one) click the drop down box and select "My Computer".

Next click the Search button. All the files that match your search criteria will appear on the right side of the Search window.

Don't click on it, just note the location.  Most likely that will be ms's next question.

New info May have solution. No time to xplain now, will post tomorrow after I try it

69 RAT I 'm just editing this instead of double posting the link works for me now.I don't know whether the fix will work or not.I will let someone with more knowlege on using that type of fix help you with it.

No, search your hard drive, not the registry, for the file.  Has to be somewhere or it has been removed and the entry, which may be in win.ini, or one of the other ini files, is a dead call. 

Pauls fix:  Looks like he is changing the attribute of the file but not absolutely sure.  If all those files are supposed to use shared then it may function correctly.  Don't know enough about writing batches for command line in XP to say whether it will do what it is supposed to do or not.  Also, I did not see a post in the other forum saying that it had worked for someone either.   If you're at the end of your rope and plan on doing a full blown reinstall anyway, I would try it at that point.  Further down in the other forum it spoke of copying the files back from the xp cd, which might be a good idea as well heres a link to the search suggested in the other forum: http://support.microsoft.com/search/default.aspx?qu=lsass+error   I guess it comes down to that in the worst case scenerio you'll need to format your HD, or at least delete the windows directory, and do a full blown re-install but if the batch file works, you're golden.  I would like a copy of the that funky file if you can find it on your hard drive.  Like to kick the tires on it, so to speak. 

You could cut and paste the batch file information and send it to ms for a quick once over.  From looking at the search on MS, they have had a good number of problems with lsass.
Edit:
Yeah, thats why I'd only do it as a last resort to prevent the computer from mysteriously going out thru the nearest window  . 

 69 RAT: I don't think this is a problem you are having with XP but here is something I found while looking about the problem with 98.98SE & ME aparently the capital I in these OS's looks just like the small L. Some hackers were hiding a virus this way I'm going to post examples of how it looks since I have ME I don't know if it will look that way on an XP OS.
Ilsass.exe this one has a capital i for the first letter
llsass.exe this one has 2 small L's
On my PC they look identical.
