Hello.

After a full restore of my main partition from a Norton Ghost 2003
image file, all seemed to be going well. Until after introducing
user name and password, it spitted me to login screen again...
In my fast machine, I barely could see a polite "storing your config
etc." message before returning to login screen. No matter as admin, user
or whatsoever.

Booting with the original install cd in recover console, it no asked me
for passwords. Symply denied me access to \Documents and Settings
folder...

I had FAT32 filesystem, cos I was burned in the past with NTFS...
Mi OS is Windows XP Pro SP1

I hope this will be a silly thing with a silly solution.

Thanks for your time and have a good day.
