When you right-click on Active Directory Users and Computers \[<Domain Name>\] and press Connect to Domain Controller, you cannot successfully connect.

This behavior is indicative on incorrect permission on the HKEY_LOCAL_MACHINE\SYSTEM\CurentControlSet\Control\SecurePipeServers\WinReg key of the remote servers registry.

To resolve this problem, use Regedit / Edit / Permissions to verify/set the following minimal permissions:

Administrators group          Full Control, Read                              Backup Operators group        Read                              Enterprise Admins group       Read                              Local Service account         Read
NOTE: If a group or account is missing, press Add, type the identity, press Check Names, and OK.
