Logging off of WHS from Win 7?

Searched with no results, high and low and google...get too much cross reference. Should be a simple fix...
Help is appreciated.

New install of Windows 7 here, new user. I connected to my WHS HP mediasmart server files, and got annoyed at my password login information popping up more frequently than it did with Vista. Typed "Guest" instead of my administrator login info when prompted, and checked save information. I wasn't worried about the save information check box because it obviously didn't take the first few times I typed in my administrator info. This is a home computer, so I am not worried as to who goes on and accesses my information. Problem is, I have seemingly permanently restricted my access to password protected folders, as I cannot log in as administrator and am stuck as a guest.

I have restarted server and computer, changed computer name, changed computer network name, disabled network card, searched high and low for where this information may be saved, and even made another account on my Win 7 build ...which info is still saved for

Any suggestions to delete this info, or be given the opportunity to log in again would be appreciated. Please let me know if this is not detailed enough.

I need to access some of my WHS files in order to install the WHS control center on this computer. Some of these terms may not be verbatim, but I think you will understand.

Thanks Again!

disabling simple file sharing should remove the cached username/pw

No such luck, tried it and still automatically logs on afterwards. Any other suggestions?

Sorry to bump....but still having same issues. I don't really want to format a system due to saved log in information. Any help or suggestions would be greatly appreciated!

I just want to connect to my server from home. I am currently connected, but with limited access due to user privileges. I am trying to log off as guest user, but cannot find an option to do so. I can log on from any other computer, and even remotely from the problematic machine. Again, any help or ideas are appreciated.

*Bump* This is now an issue on my XP computers as well. If a friend comes over to log onto my server....I yell at them to type in "guest"

Later when I go to log on, I remain on as "guest" and cannot log in as my privileged account.

At some point while I've had this server I would have to log in every time the computer was turned on.

It's so pathetic. I have 3 computers and cannot access my resume or hardship letter for my loan modification. I shouldn't have to format 3 computers to access files on a forth. I can't even set up WHS console on my main computer because the updated files are contained in a restricted folder as well...

Haven't had time to format - although shouldn't have to?! Suggestions appreciated!
