Here're some general tips to verify for Windows Vista computers:
You must have administration rights/privileges over your domains, workstations and servers of your network: you must be a member of the "Administrators" / "Domain Admins" groups.
The "RemoteRegistry" service must be up and running on the remote computer.
Network discovery need to be activated. When Network Discovery is on, the Windows Vista computer can see other network computers / devices and become also visible to other network computers and to our software.
This is in Control Panel, Network and Sharing center
- File and Printer sharing :

Before administrate a Windows Vista station, we strongly recommend you first to DEACTIVATE "User Access Control" aka UAC.
This is in "Control Panel" ,"User Accounts" , "Turn User Accounts Control on off".
To take the remote control of Windows Vista computers with "TightVNC", you'll have to add an exception on the remote computer, into the Windows Firewall for the communication port used by the program (5900 by default) and/or for the program "\Windows\Pointdev\VNC\WinVNC.exe" (VNC Server service) if you use version 1.X of the remote control tool, or for the program "\Windows\Pointdev\VNC\tvnserver.exe" (tvncserver_Pointdev service) if you use version 2.X.
Last, check in the Network Settings if NetBIOS layer is enabled.
