Do these devices have mulitple NICs?.
Could you create a new report which includes the MAC Address and AgentGUID and filter systems based on IsDuplicate.
This will help identify why Duplicate systems are being created.
Yes, they have multiple NICs.
Any workarounds to avoid duplicating those devices with multiple NICs
Which OS are you seeing the Duplicate systems for, Windows, OSX .....?
2008 r2 std for example, 2012 r2 std... yes Windows OS
Sorry more questions.
Are these bonded NICs on the Servers for Resilience, or do they form part of a Cluster?
One server is 3cx gateway and it needs two nic (one for server, one for voip telephones), other is similiar (lync server which needs two nic, one for server and other for sip trunking).
