Solution
This could be an issue where the software hasn't been installed correctly onto the target, or it could be that you have restricted access to only certain IP addresses when in use previously.
1. To resolve this issue, use the Format Disk tool in NI MAX. Check the Attempt to Restart into Safe Mode box. Select to Reset all of the networks adapters to their default settings.
2. Connect the sbRIO with host PC using Ethernet cable instead of USB cable.
