SYMPTOMS

Consider the following scenario:
  • You create a non-administrator user account on a computer that is running 64-bit version of Windows Server 2008 R2 or of Windows 7.
  • The user account joins the Network Configuration Operators group.
  • You log on to the computer by using this user account.
  • You open the Network Connections window (Ncpa.cpl) and then try to open the Properties dialog box of a network connection.
  • You are prompted for the user password in a User Account Control (UAC) dialog box.
In this scenario, you receive the following error message after you enter the correct user password:
You do not have sufficient privileges for configuring connection properties. Contact your administrator.
Therefore, you cannot edit the network adapter settings even if you are a member of the Network Configuration Operators group.

CAUSE

This issue occurs because UAC does not add the user access control entry (ACE) to the security descriptor of the access token for the thread. This behavior causes the access denied error when the access check is performed before you can open the Properties dialog box of a network connection.
