Logged-on user accounts do not receive a pop-up balloon to authenticate an 802.1X secured network in Windows 7 and in Windows Server 2008 R2

Applies to: Windows 7 EnterpriseWindows 7 ProfessionalWindows 7 Ultimate More

Symptoms


Consider the following scenario:
  • You have a computer that is running Windows 7 or Windows Server 2008 R2, and the computer joins a workgroup.
  • An 802.1X secured network connection is created in Network Connections.
  • You use more than one user account to log on to the 802.1X secured network from the computer.
In this scenario, only the first user account receives a pop-up balloon to enter credentials to log on to the 802.1X secured network. Successive user accounts do not receive this pop-up balloon. Additionally, the network connection to the 802.1X secured network is in an "Authentication Failed" state. Because of the issue, successive users cannot access the network resources, such as file servers, shared printer or applications.

Note Successive user accounts may sometimes receive a pop-up balloon to enter credentials to log on to the domain after a long wait, such as a wait of several minutes.

Cause


This issue occurs because the Wired AutoConfig (DOT3SVC) service does not handle the event data correctly when a user account logs on to the computer.
