SYMPTOMS
When you manually log on to your Microsoft Windows XP-based computer with a user name and a password, the Winlogon.exe process may prematurely end the Mpnotify.exe process. The Mpnotify.exe process hosts network provider .dll files. Specifically, the Mpnotify.exe process calls the NPLogonNotify function of the network provider .dll file. Therefore, the network provider may not function as expected.



CAUSE
This problem may occur if the following conditions are true:
 * You have a smart card reader attached to the workstation.
 * The Winlogon.exe process detects the smart card reader in the background during the logon process.

The Winlogon.exe process incorrectly ends the Mpnotify.exe process when any secure attention sequence (SAS) events are detected in the background.
