Based on the given scenario, the most likely reason for the connectivity issues reported by the users on a different network segment is that the DHCP relay agent was not configured on the adjacent network segment.

When a new DHCP server is added to a network segment, it starts offering IP addresses to devices on that segment. However, if there are other network segments that need to receive IP addresses from the DHCP server, then a DHCP relay agent needs to be configured on those segments. The DHCP relay agent is responsible for forwarding DHCP requests and responses between different network segments, ensuring that devices on those segments can receive IP addresses from the DHCP server.

If the DHCP relay agent is not configured on the adjacent network segment, the devices on that segment will not be able to receive IP addresses from the new DHCP server. This could lead to connectivity issues since devices that do not have an IP address will not be able to communicate with other devices on the network.

Options A and B are less likely to be the cause of the connectivity issues since they are related to the configuration of the DHCP server and not the network infrastructure. Option D is also less likely since private IP addressing would only affect devices on the same network segment as the DHCP server, and not on other segments.

In summary, the most likely reason for the reported connectivity issues is that the DHCP relay agent was not configured on the adjacent network segment.
