Reset saved network password? -not hacking, i know the passwords

I assume your laptop is also running windows vista?
If it is, can you try doing this and see if it works:

1- Start button -- type "User Accounts" (no quotes) and hit Enter.
2- Click on Manage your network passwords located on the side menu.
3- You can add/edit/delete accounts/passwords

If it is XP, can you try this:

1- Start Menu > Run > control userpasswords2 and press Enter
2- User Accounts Dialog Box will appear
3- Go to Advance Tab and Click on the Manage Password Button
4- Remove the account that you want to delete

Hope this helps.

i tried that, and yes it is vista. unfortunately it didn't have anything saved under there, and it wont let me add an account with a blank password (not to mention that i dont want it to log in as administrator since someone could delete/edit my files).

I am still getting the error message access is denied when i try to go to run and type in the \\computername

I think you should try enabling the use of blank passwords in vista. It's by doing this:

1. Start -> Run -> gpedit.msc
(This will allow you to edit the Group Policies
)

2. Computer Configuration ->  Windows Settings -> Security Settings -> Local Policies -> Security Options
3. Double click on Accounts  -> Limit local account use of blank passwords to console login only.  (Disable this option)

(Also try setting the 'Network access: sharing model and security for local accounts' to 'Classic - local users authenticate themselves')

Also you might want to allow guest account access to the network.  

Hope this helps. If the problem exists we can still figure something out hopefully :)
