[duhno]

I did a TOTAL reformat (XP), redownloaded my Norton Internet Security 2005 and went to run it and it told me I need Administrative permissions to do this. The only visible account on my pc now...which is the "Administrator" account that came with the reformatting. I did change the name of this account but that's all I did. Under the name change it says "computer administrator"and "password protected"(in the user accounts section of Windows)...and NIS doesn't recognize this for some reason.
By any chance in doing this, did Windows create another user account and this is the account I'm actually using instead of the Administrator account, just having the priveleges? Because I did try to change what I put as the new name on this account back to "ADMINISTRATOR", and it said there was already an account with that name...but it's not visible. If this is the case, what do I need to do so NIS recognizes and sets by the account that I use-THE VISIBLE ONE? Does the non-visible account draw 1st attention when an application is looking for the administration rights? Or is it something within NIS that I obviously don't know, that's making this complicated for me as a new user?
Leave it to a "newbie" to complex issues even more without knowing...lol It's probably simple, but I'm not getting it. Only getting questions and headaches!
Any help or suggestions would be great...really need my protection back on my pc ASAP!
