I recently reinstalled Windows XP Professional on a Dell D420 that has a biometric fingerprint scanner which is utilized by Wave Systems Embassy Security Suite with the Dell Trusted Platform Module(TPM). I thought I had it working properly after the reinstall but I kept running into errors so I attempted to follow the documentation to delete users, enroll fingerprints different ways, and other instructions that I could find on the Wave Systems web site. I seemed to always end up at the same place which was I could type in a password or swipe my fingerprint but when the attempt was made to automatically login to Windows XP a error would pop up stating that no fingerprints were active for this user. Once I clicked the OK button on the error I could swipe the exact same fingerprint and I would login to Windows without issue. Below are details regarding the error, other steps I attempted to resolve the issue, and the final steps that resolved my problem.
I changed the system board on my Dell Latitude D420 because of the on-board Ethernet port only working some of the time. After replacing the system board it is required to enable TPM again and activate it for Windows login.
First you will need to enable TPM in the BIOS.
