Domain Users are unable to login

Within the past few days we have had a number of Vista computers and Windows Server 2008 R2 servers that are preventing users from typing their password in the password field after entering CTRL, ALT, DEL. EventID 1000 Faulting application LogonUI.exe version 6.0.6001.18000 time stamp... faulting module ADSSProvider64.dll. If I remove the GINA application from ADSelfService Portal, within a few moments the user can then login.

                  New to ADSelfService Plus?
