I have a friend for whom I put together a computer with Vista Home Basic on
it.  She is not very computer savvy, and relies on me for support.  She
"suddenly" began having all sorts of problems that I couldn't explain.  (The
one that made her call me was that the computer was asking if she wanted to
format her DVD... even the Vista installation DVD.)  I thought it was a
communications problem between her and myself, so I had her bring her
computer to me so I could look at it.  Sure enough, it was doing what she
said.  I saw that she had the Google toolbar installed, and after I was sure
she didn't use it I tried uninstalling it.  It didn't work.  After further
investigation,  I determined that she couldn't delete files, either.  Nor
could she run anything that had the User Account Control on it.  I
double-checked, and she IS the only administrator account.  After lots of
dead-ends and talking to her, I found out that her son had changed the name
on his account to "SAM" about the same time she started having problems.  I
didn't think much about this, but as I was going over this in my head, I had
a flash....  SAM ...  Security Accounts Manager Service.  

Just wondering....  Could this be the source of my friends problem?  Or
should I look elsewhere?
