When the DNA Agent is installed, and it connects to the DNA Server for the first time, it provides its MAC address. This is checked by the DNA Server to see whether there is already a record with the same MAC address in the DNA database.
If a record with this MAC address does exist the DNA Server will provide the DNA Agent with the unique Node ID for this record. If, however, the MAC address does not exist, the DNA Server will provide a new Node ID to the DNA Agent.
From then on, whenever the DNA Agent connects to the DNA Server, it will supply its unique Node ID to the DNA Server. Any information for this DNA Agent will be updated in the DNA database for the record with the same Node ID.
If you are using imaging software such as Ghost or Drive image and have a DNA Agent installed before creating the image, each machine you restore the image to will have the same Node ID. This will cause the record in the DNA Database to receive information from different Agents which is undesirable.
To avoid this, you must delete the Node ID registry entry from the DNA Agent before taking the image. This means that when the DNA Agent connects to the DNA Server, it will supply its MAC address, which will be unique and will, therefore, obtain a new Node ID.
Delete the DNA Agent unique Node ID
- Open the services.msc window.
- Stop the NetSupport DNA Agent service (so the Agent will not be able to connect to the DNA Server and retrieve its Node ID). You will need admin rights to do this.
- Run regedit.
- Navigate to the following registry key:
32bit HKLM\Software\NetSupport Ltd\NetSupport DNA\Client
64bit HKLM\Software\Wow6432Node\NetSupport Ltd\NetSupport DNA\Client
- Delete the NodeID registry key.
- Image the machine.
This article is advising you to modify the registry, and you do so at your own risk. Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow the steps carefully. For added protection, back up the registry before you modify it.
