One laptop is getting IP from DHCP server. IPconfig shows the new IP, but Ping to the <hostname> of the laptop name resolves to the OLD IP address. DNS zone also hosts the records mapped to the old IP.
DHCP server belongs to a different trusted domain (abc.com) and client PC belongs to a different trusted domain (zyx.com). In the scope of the DHCP server; both DNS servers' IP is added; means DNS server of both the domain. DHCP Scope is configured to "Always dynamically update DNS A and PTR record".
I tried with ipconfig /flushdns and then /release /renew, But still in the DNS the host record maps to the old IP.
Please advise what could be the possible reasons?
