What do you mean by everything was lost? If you mean files for that user
look under documents and settings for the user profiles to see if they
exist. Use the command net localgroup administrators to see what users are
in the administrators group. One of those is the built in administrator
account and try renaming the one that you fell is most likely built in
administrator or try logging on as those users as changing a logon name
would not deny access to the user's profile. You can download PsGetSid from
SysInternals to find the SID of a user account. The built in administrator
account will always have the user SID shown below that ends in 500 though
the number in between S-1-5 and 500 will vary based on computer or domain.
Worse case is that unless the files are encrypted via EFS any administrator
can gain access to any file on the computer though he may need to take
ownership first before granting himself permissions. --- Steve
