Thank you for your message.
Please clarify if you are on a local network with Active Directory
If the Viewer is installed on a computer that belongs to an Active Directory network, the Viewer fetches the AD tree automatically.
If this is the case, please try to disable showing the Active directory tree. Open the Viewer
, click Tools ➝ Options
, navigate to the Misc
tab and enable the Hide default domain controller
Please note, that endpoints in your Active directory tree also count.
If your computer doesn't belong to Active Directory network, please try to reset the Viewer options by deleting the file config_4.xml
found in %appdata%\Remote Utilities Files\
folder. This will reset the Viewer settings/options. Your address books won't be affected by this action.
Hope that helps.
