Symptoms

Consider the following scenario:

  • You have a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1 in a network environment.

  • You use Windows Explorer to view all the computers that are connected in the network.

  • Windows uses the Computer Browser service to map the computers that are connected in the network.

    Note The Active Directory directory service is the default service for mapping computers that are connected in a network. However, Windows uses the Computer Browser service when the Active Directory directory service is not available. For more information about the Computer Browser service, go to the following Microsoft website:

    General information about the Computer Browser service

In this scenario, Windows Explorer does not display all the computers that are connected in the network.

Cause

This issue occurs because the call to the initialization function has a wrong priority.
