It is possible to change the IP address of the DNA Server within the Agent configuration via Group Policy using the ADMX templates provided with the software. You may need to do this if the DNA Server has been migrated to a new machine or the Agents are currently configured with an incorrect address.
If you haven’t already imported the NetSupport DNA ADMX Template file, please refer to the following technical article for steps on how to do this:
How to apply the NetSupport DNA ADMX Template file
Once imported, open the Group Policy Management Console and create a new policy at the level of your choice (it needs to be at a high enough level to apply to all DNA Agent machines).
Edit this policy and navigate to Computer Configuration > Policies > Administrative Templates > NetSupport DNA Configuration.
Edit the “NetSupport DNA Server Address” policy, set this to enabled and then enter the new IP address or hostname of your DNA Server machine.
After the Agents have picked up this policy, they will then start connecting to the DNA Server using the newly specified address.
