I have Norton Sytem Works 2003. For the last few months, I've been
running Windows 2000 as my operating system -- and I can't get
Norton's Disk Doctor to fix errors.

It's a catch-22: The Disk Doctor program diagnoses & detects errors,
but then tells me it can't fix them because the operating system is in
"control the operating system." Disk Doctor also tells me to re-start,
which I've tried; but it can't "control the system" on startup either.

I've always run Norton utilities on Windows systems, until I got
Windows 2000. What's the story here? Is this program incompatible with
2000?

I may try running Disk Doctor from the Norton CD -- but I suspect that
won't work (or is this the solution?).

Help!

logged in as administrator?

Interesting question. I know only one thing about "logging in" to my
own system:

I have a little utility called setclock.exe. When I run it (daily),
the program asks me whether I'm logging in as administrator or as
myself. I answer as myself, because I couldn't remember the
administrator password.

So I guess I'm telling the computer I'm NOT the administrator....But
maybe only the administrator can run a program like Norton, with its
access to system info? I suppose that's what you're suggesting.

So I wonder how do I tell if I am logged in as administrator?  And how
do I check what the administrator's password is, and/or change it, or
whatever?

You're probably logging in with administrator privileges otherwise
you'd be having a hard time installing any new software.  From Control
Panels, go to "user accounts" or "users and groups", and I think that
brings up the list of users that have accounts on the computer.  It
tells you whether each account is a member of administrators, guest
uers, power users, etc.  Make sure it's administrators.

Your account doesn't need to be named "administrator" -- it needs to
be a member of the "administrators" group.

Other suggestion I have is hitting ctrl-alt-delete, going to Task
Manager, and forcibly doing "end process" to as many processes as
possible (everything except taskmgr.exe, explorer.exe, winlogon.exe,
and system).  There are probably 20 things running, and windows might
allow you to kill half of them.  Then run NDD, and then reboot.

to snsh-ga:
Thanks, but actually I don't think these solve it. 
Thanks for the info about users & administrators; I'd never known
that. Anyway, I am in the administrators group, so that's not the
problem.
And I do know about the task list, and I've often halted everything in
it, for one reason or another--usually before I run any Norton
functions (like updating the virus info), so that's not it either.
I appreciate the suggestions, but I guess this is still a puzzle. I'm
hoping I'm not the only person to have encountered this... ?

The way NDD works on Windows 2000 and XP is that if it finds it has to
fix any errors on a disk where Windows has files open, it sets a flag
that tells Windows to run SCANDISK on reboot.  NDD itself is not able
to run in this mode.  However, I think you have to be an administrator
to do this.

What happens if, in My Computer, you right click on the icon for the
disk, select Properties..Tools..Error Checking, check the box for
"Automatically fix file system errors" and then Start?
