@jonathon_eades: "Everyone else sees the new intranet. Mine still loads the old one." IT moved the site to a new server last night. ping hub.contoso.com goes to 10.0.0.15, the OLD server. nslookup says 10.0.0.42, the NEW one, so DNS is right. The twist: ipconfig /displaydns shows this PC cached the old answer, with about 20 hours left before it expires. ping and the browser read that cache; nslookup asks the DNS server directly, which is why they disagree. Fix: ipconfig /flushdns. ping now goes to 10.0.0.42 and the new intranet loads. nslookup right, ping wrong? Flush the DNS cache. Did you know nslookup skips the cache? 👇 #CompTIA #CompTIAAPlus #helpdesk #techtok #itcareer
