It's been ages since I posted this but the reason it shows duplicates is becasue it's discovered the name, but doesn't know anything about it and therefore assigns it as a 'Network Resource' (The lowest form of asset in Altiris - it basically means it has no idea wtf it is e.g. it can't authenticate to it but gets it's name or ip address from a scheduled discovery task)
It then subsequently has the Altiris Agent Installed, and knows it's a computer because of it, but because it keeps old information in there forever, the old Network Resource' record is never removed until I manually delete it.
This is one of Altiris's biggest sins - automatically classifying devices, and not letting me change the classification. oh such a simple fix in code, but so a huge problem for so many sites, and especially for noobs!
I have the follwoing irritating problem which is caused by this:
1. We import about 500 network devices from an Excel workbook, as 'Infrastructure Devieces' (we can't use snmp for about 6 differnet reasons)
2. The discovery tasks discover not the full list of 500 devices, but lets say about 100 of them. So now I have 100 duplicates that I haven't figured out how to deal with. If I delete them they will just come back on the next icmp discovery. Also it's not possible to 'merge' two different resouce types i.e Network Resource and an 'Infrastructure Device'
:(
