Hi, Please help clarify the following questions: 1. Does the smart card logon error occur for one user or all the users? 2. Did the smart card logon work after you enable it? 3. Does the issue occur on some computers or all computers? What is the OS version of the problematic computer? For the error “the system could not log you on. your credentials could not be verified”, please check the following support article first: Guidelines for enabling smart card logon with third-party certification authorities http://support.microsoft.com/kb/281245 Although the article is with third-party certification authorities, the checklist is similar for your situation.
