Problem:
A BACnet device created in the server project is configured to use Whols/Iam for Device Discovery. Users may encounter the following problems:

1. Automatic tag generation fails in the new project.
2. The server fails to connect to the device on projects that have been moved from one PC to another.

Possible Cause:
WhoIs/Iam is a Broadcast UDP message. In most cases, there is a smart switch located between the server and the physical device that is blocking Broadcast UDP messages.

Solutions:
1. In the smart switch, change the setting to allow Broadcast UDP messages.
2. Change the device's Discovery property to the BACnet device's IP address.
