Use the Internal DNS Lookups tab on the Hub Transport Server properties to specify whether to use the Domain Name System (DNS) servers that are associated with a network adapter or manually configure DNS servers. Internal DNS servers are used by connectors that resolve IP addresses for servers inside the organization.

Use network card DNS settings

To select an installed network adapter from the list, select Use network card DNS settings, and then select a network adapter. The server will query the network adapter when it looks for a DNS server. The default setting is All Available. If you select this setting, the server will use the DNS servers for all the adapters on that server.

Use these DNS servers

To have the server select from a list of manually-entered DNS servers to query when it is resolving a remote domain, select Use these DNS server. To add a server to the list, type the IP address of the external DNS server, and then click Add.
