I have automatic updates enabled on my laptop. (the laptop originally had XP
Home installed, but I upgraded to XP Pro).
One evening I let the update reboot the machine. I could not then log on.
At all. To anything!!

My administrator password is blank to my local machine. The error message is:

The system cannot log you on due to the following error:
The program issued a command but the command length is incorrect.
Please try again or contact your administrator.

I have tried logging on to my domain (with a proper password) but I get
exactly the same message.

I believe that I will have to reinstall XP but don't want to.

Any ideas... this is kinda urgent.

Many thanks

Steve
