your secondary server pointing to previous primary dns for external name resolution
now you need to point it to present primary dns server
you need to go to secodary dns server console and go to dns server properties and go to forwarder tab, add present Primary dns server ip there as forwarder and keep it at top in the list
this will ensure that external name resolution queries will get forwarded to present dns server
add "DNS" as a topic so that more dns experts will help you

Question how allow secondary DNS point to the present dns server?

The answer depends on how the DNS servers are being assigned to clients. Check the IPv4 properties of each client's network adapter:
IPv4 properties
If the Use the following DNS server addresses radio button is selected, you can modify the client's list of DNS servers in the fields below it. If the Obtain DNS server address automatically radio button is selected, however (as it is in the image), that client is getting its list of DNS servers via DHCP, and the DNS server list will need to be changed on the DHCP server. The steps for making that change will depend on what is acting as the DHCP server on that network.

Be aware that changing the list of DNS servers assigned through DHCP will affect all DHCP clients on the network.
