Is the windows XP client's domain the same as the computer being scanned?
Is this the only error in your errorlog.txt file?
All the computers are in the same Windows 2003 AD domain. The Windows XP computer running the service is a member of the domain. All services are running with the domain\administrator account.
Every computer on the domain generates the same entry in the errorlog.txt except the Windows XP computer running the Lansweeper service.
The Connection tester application gives OK on most of the computers.
Even the AD domain controller generates "scanning multiple domains requires the premium version" in errorlog.txt.
