Hi, I hope this is the right forum for this question. We are using Smartcards to authenticate in our company. So every PC (workstation or notebook) needs a cardreader. Our notebook-users also have UMTS-cards integrated. The problem is: When UMTS is turned on the Credential Provider on Vista-Logon-Screen always shows an additional cardreader for UMTS. I think thats not nice but no problem. The problem is that this additional Cardreader always shows a "Smartcard error". Is this a bug or can I configure this in any other way? Thanks. BR
