When User Manager is launched from Lookout menu (6.02 Full Development Version), a "User Manager for Domains" window opens and an error dialog with the same title says "Could not find domain controller for this domain."
Hmm.. do you perchance have LabVIEW / DSC 8.0 installed on the same machine? I know LabVIEW / DSC 8.0 has added "domain" funtionality to the security stuff. It could also be the latest Logos.
