Can ping a server by fqdn but not by host.

-

hello team,

we have server can connect using \\ or rdp using fqdn not host name. earlier used work not. can please provide basic checks start see might problem

kits

remove public ip address form dns , add internal dns setting ip address meinolf suggest.refer below link dc/member server/client dns setting recommendation.

-->> dns configuration on domain controller:
------------------------------------------
1. each dc / dns server points private ip address primary dns server , other internal/remote dns servers secondary dns in tcp/ip property.
2. each dc has 1 ip address , 1 network adapter enabled (disable unused nics).
3. if multiple nics (enabled , disabled) present on server, make sure active nic should on top in nic binding.
4. contact isp , valid dns ips them , add in forwarders, not set public dns server in tcp/ip setting of dc.

-->> dns configuration on clients , member servers:
-----------------------------------
1. each workstation/member server should point local dns server primary dns , other remote dns servers secondary.
2. not set public dns server in tcp/ip setting of client/member server.

once done above, run "ipconfig /flushdns & ipconfig /registerdns", restart dns server , netlogon service on each dc.

the ipconfig details posted  i've noticed dc has no primary dns suffix. condition called "disjointed namespace." can fix that.in computer properties, computer name, "more" button. must put back domainname( eg contoso.com) field.the machine must restarted take effect. 

the primary dns suffix dns client service (partly dns dynamic update service) on dc uses register ad information dns looking matching zone name, is domainame( eg contoso.com) zone. if missing, ad (specifically netlogon service) can't regsiter data dns.

then run commands:
ipconfig /flushdns
ipconfig /registerdns
net stop netlogon
net start netlogon
action insures dc registers proper records dns ad can function

hope helps

best regards,

sandesh dubey.

i have pc has power settings pushed out default domain policy in ad environment. of course on local machine "some settings managed system adminstrator". the machine temporarily no longer in contact domain controller (it's been physically moved , not on same network now) can't updated gpo settings. i believe if edit local group policy won't make difference because of group policy processing , precedence. since it's temporary away ad network, still want use settings of ad user. is there somewhere in registry stored can edit power plan manually until can sync domain? (i need prevent sleeping while plugged in - it's set 1 hour) thanks! allen crist i found site: http://gpsearch.azurewebsites.net/#7916 i able add policy to hkey_local_machine\software\policies\microsoft\power using specs found on site. looks solved issue. i'll report if didn't. thanks! allen crist ...
