Are you the ONLY administrator?
Check all the services the administrator is running under Task manager-->processes. Click on CPU and see whats taking the max amount of resources ... if its the explorer it might be linked to another service running as ADMINISTRATOR. You could also try Stoping a service checking CPU usage and Starting the service again (it could actually be linked). The last person I know that got 100% CPU usage when they logged in as administrator was because they had SETI processing in the background and it was loaded with the Administrators script ;-(

Not much ... but anything helps!

Go to sysinternals.com and download a couple of their tools. First try ProcExplorer and then TcpView: http://sysinternals.com/ntw2k/utilities.shtml

Proc Explorer will show you all the processes open and running. What you'll be looking for is anything unusual. You can shut things down one by one and see if you can get your cpu back down to normal.

TCPView will just show you if your machine is making an abnormal amount of connections to a remote host - like a virus or trojan, etc. It will map that out to a process so you can then remove it or kill it.

Hope this help some. Good luck.

If those do not work you might just want to recreate the SAM file. www.winternals.com look for ERD cammander. This utility can help recreate the SAM file and admin acct.
