Fingerprint Enrollment in constant endless loop

[andyP Community SuperMod]

jidus, welcome to the forum,

try disabling cssauth.exe, hopefully this will do the trick also.

Unfortunately, neither disabling the exe with msconfig, nor changing its name helped the problem. The fingerprint software still loads at the login screen, and I still have the loop error.

Did anyone ever resolve this?  I've been trying to fix the same issue on a T61.

i was just having the same dumb problem with my T60 -- endless enrollment loop.  spent like 2 hours renaming and disabling stuff, no use.

eventually i managed to open the "ThinkVantage Fingerprint Control Center" in Safe Mode.  Open Settings -> Logon -> switch to Standard Windows Logon.  That should do it.    Nothing else needed to be disabled.

This has been happening to me on a T61 off and on.  I have found that if I do not try to log in for, say, 8 minutes after getting the logon prompt, it is more likely towork.  However, this morning, not even that works.

I try to logon with either fingerprint or username/password, and end up on the "Enroll" panel for fingerprints.  My username is already entered on the form, read-only, with a apassword prompt.  I enter my password and get the error "that passport cannot be used..." and then get logged off.

I have not yet tried the Safe Mode/rename/disable approaches, but these just turn off the feature.  How do I fix it?

It's amazing to me that Lenovo has shipped a product that won't let me log into my own laptop.  And incredibly frustrating that I cannot log in at all.

How can this be fixed, short of respinning the whole disk, which I just did a couple of months ago.  Is it necesary to do this every few months?

Hmm...

I seem to be in the same situation as well now?

My IT people have been out to see my lap (T61) and have had no luck.

They want to try a full rebuild, but I have important project information on board that has not been backed up anywhere else yet.

I really need to gain access again to this lap.

HELP

I'm running into the sam issue as well.

I've found a few work arounds.  First and easiest method is pull the battery for a minute, Second go into the BIOS goto Security Fingerprint and reset all fingerprint data.  If these methods don't work hit f8 on boot go into safe mode and log on as local administrator.  After your in safe mode goto start>run>regedit.

Drill down to: HKEY_LOCAL MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Set the following keys to:

BaseGina=MSGINA.DLL

GinaDll=MSGINA.DLL

This should get you around the loop.  I'm still interested in a real fix not a work around if anyone has any further information.

I don't know if will fix everyone's issue, but I dealt with this problem today.  I went through all the same things listed here.  The last resort was pulling the hard drive out for a while to get some files I needed on my desktop and then plugging it back in.  Went to the bios and disabled fingerprint at start function in security.  Bam!  fixed. 

Disabled the software once I was in windows and now I'm back in business.  I'm done with this stupid thing.

I don't know if it was a fluke, but give it a shot.

Boot into Safe Mode

Go to Start->run type in regedit

In the registry go to HKEY_LOCAL_MACHINE\software\Microsoft\windows nt\currentversion\winlogon make sure key baseGina needs to point to msgina.dll

If the Base Gina String is not the registry add it: create a string under the Win login Key called basegina and the value should be set to msgina.dll

Also locate and change the GinaDLL string valve to msgina.dll

Then go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\TVTGINA

Set MonitorInterval to all "f"s

Once you have changed both reg keys close out of the registry and reboot.

Now you can login like normal, uninstall the fingerprint software and reinstall\update to a newer version or roll without it.

We have seen this happen after deploying full drive encryption and single sign on with the fingerprint software on T60/T61's. (Fingerprint software version 5.8.2 ) We remote into the registry and change the ginadll to msgina.dll (from vrlogon.dll). This will get you back to the Microsoft logon prompt and you can login. Then open the fingerprint software to check the settings and the key will revert back to vrlogon.dll, the looping will stop and you can use the fingerprint sign on.
