Overview
You require a list of agents showing their machine names and the corresponding agent build number as well. There is no direct report that shows the agent build number but this information can be obtained using SQL queries on the LanGuard scan results database.
Solution
Run the following SQL query on the LanGuard scan results database (named LNSSScanResults12 by default):
select
c.[Domain], c.DnsName [DNS Name], c.Name [Host Name], a.BuildNumber [Agent Build Number]
from Agent a
join Computer c on a.ComputerID = c.ComputerID
where a.Status = 1
order by c.Name
The results will show the machine names that have agents installed, along with their corresponding agent builds as well as DNS and Domain names.
You may modify the query as you wish (for example, sorting by the build number) but such modifications are not within the Support scope.
