The User Profile Service failed the logon.

[Guest]

I've been using Windows Vista Ultimate for almost three months now, and all
of a sudden tonight I couldn't log on to my laptop. Every time I tried I
received the message "The User Profile Service failed the logon. The User
Profile failed to load." I had successfully logged on to it only five hours
earlier, so I did not understand what could be going on.

Fortunately after Googling the error message (I originally used Microsoft
Live Searct, but did not get any results), I found someone who had a similar
error and had found that his profile had entered a backup state. I logged on
with my domain administrator account (it's good to be the king sometimes) and
examined the keys under HKLM\Software\Microsoft\Windows NT\Current
User\ProfileList\ and was able to find the key for my user id SID. Sure
enough, the key had a ".bak" appended to it and there was an identical one
that was set to a temp directory. I renamed the other key, removed the
".bak" from mine, and changed the State property under my key to 0. This
allowed me to log in.

Does anyone know what might have caused this issue? If this is a bug, its a
pretty severe one, as I can just imagine a help desk trying to resolve this
over the phone with their laptop users who all of a sudden can't log in.

Thanks.

Hi Dave,

Welcome to Vista x64 Forums. arty:

See if this can help you. You will probably need to boot into Safe
Mode.

Brink, I followed the link in the above post. I go through step one and on
to option 1 through step 6 B, I never completed step 6 C or any steps beyond
that. Then I had to leave and my husband said I probably needed to start
over so I closed everything and restarted the computer, then amazingly when I
attempted to log in at my administrator account with the same password, it
let me in, looks like I lost my settings but I am in. My query is this,
without having completed the final steps (6C and on) have I screwed up
something else ?? Also I copied the numbers from the jpeg images exactly as
they were shown, was that correct ? Any assistance or passing of knowledge
would be so appreciated. Thanks for your time. D

Hi D,

NO, you didn't mess anything up. You just didn't finish. Your settings
will most likely be in theuserprofilein step 6C with the "bak" at the
end of it. You can just go back and double check what you alread have
done and then finish up to have it back the way it was. That's all.

Hope this helps,
Shawn

Hi, all I have similar problem.

Though the issue is Admin account works OK just I can't activate Guest
or additional user account and get the same message. I have check
registry and everything appears OK, ie. no .Bak file. Also none of
the guest profile or user profile aside from administrator profile
appears registered?? I'm running a new Toshiba and it has the
fingerprint reader could it be something to do with that? (long
shot..)

any advice appreciated

Hi. I came accross this site when searching google for a fix.

I was hoping somebody could assist me with my frustrating problem.

When I boot into safe mode I get a black screen with a cursor and safe
mode written in each corner.

I tried to do a system restore yesterday and it seems I have really
messed up my laptop (Dell inspiron 1720). Luckily I backed everything up
before this mess happened.

Booting from the OS DVD doesn't seem to work and I don't have a repair
option on thr boot menu.

If anyone could help me dig my way out of this hole, I would be
eternally grateful!

Thanks
done

First, booting from the DVD may require that you go into BIOS and change
the boot order.
Next, obviously the DVD drive must be working, and capable of boot.
Otherwise, you will need to have alternate media or a replacement drive,
and use it to start the boot process.
Some Laptops have a restore to factory image stored on the HD.
Using it is Mfr/Model dependent. Check the Dell website or your
documentation for information.
