i have noticed on pc cannot connect various hosts in network. upon pinging host, find ip address not supposed , has taken on external address. issue can fixed running "ipconfig/flushdns" followed "ipconfig/registerdns" , can connect host right ip. discovered not isolated 1 pc, other users see behavior when looking @ "ipconfig/displaydns" seems bind same external address. found external address ip our website our internal domain shares same name. can offer insight/suggestions problem. many thanks!

ok, pretty sure caused issue. marking resolved. found best practice info below open new thread this. thanks

  • all domain-joined computers must use internal dns servers. if domain-joined computer configured use external server alternate dns server, temporary lack of connectivity internal dns server cause machine begin using external server resolution. external server unable resolve queries inside ad domain, , client machine not automatically revert internal dns server when connectivity restored. manifests inability access resources in domain affected machine. be advised if using small-office/home-office (soho) router assign dhcp addresses client machines, assign external dns servers clients unless has been manually configured otherwise.
