Looking at the query, I think it's case #1 when there is more then one optical drive present...
I'm a bit rusty on my SQL syntax, anyone know how to fix this bug?
SELECT TOP 100 PERCENT dbo.tblComputers.Computername AS computer, dbo.tblOperatingsystem.Description, dbo.tblComputers.Domain,
dbo.tblCDROMDrive.Caption
FROM dbo.tblCDROMDrive INNER JOIN
dbo.tblComputers ON dbo.tblCDROMDrive.Computername = dbo.tblComputers.Computername INNER JOIN
dbo.tblOperatingsystem ON dbo.tblComputers.Computername = dbo.tblOperatingsystem.Computername
WHERE (NOT (dbo.tblCDROMDrive.DeviceID LIKE '%DVD%'))
ORDER BY dbo.tblComputers.Computername
