Security Policy Issue

My regional manager brought me her HP laptop today this system has never had a logon screen.
Now it comes up with a logon for Owner there is no password on this account. If you simply hit enter i get the error. “Local policy does not allow interactive logon” I have used a program that reads the password setup on an NTFS partion and verified there is no password on it or the Admin account that comes up with F8 in safe mode.
I Need a way around this as reformating the system is not and option. What i need in paticular to use the work around i have found is a program that will let me access the NTFS file system on c: from does everything i can find will only let me Read the NTFS not work with it.
