Trying to decipher an MS-Dos example to reset a password.

[The Backlash Cometh]

I think my problem is that I have an old XP which was updated to Service Pack 3, and the configuration doesn't lend itself to a quick fix when it comes to resetting the password. I think that's how the problem started. I had just changed my passwords for both the Admin and the one guest. But the computer accepted a long password which I used for the guest, and at log in it was obvious that it was two digits too long. Not enough space to input it in. However, I don't understand why it's not accepting my password for the Administrator, but I'm hoping to fix the whole problem by deciphering this example:

Here's the code words: closed bracket: cb
open bracket: ob


NET USER
(ob) username (ob) password |*(cb) (ob) option (cb) (cb) (ob)/DOMAIN(cb)
username {password | *} /ADD (ob)option9cb) (ob)/DOMAIN(cb)
username (ob)/DELETE(cb) (ob)/DOMAIN(cb)

I've tried all kinds of combinations but I keep getting error messages.

This was my best guess: NET USER (ob)Dummy (ob)password | *(cb)(cb) (ob)/DELETE(cb) (ob)/DOMAIN(cb)

Any help would be appreciated.
