Server 2008: No logon servers available to service the request.

hello there.  have set (i think) new windows server 2008 installation running ad in new forest itself, , have been looking clients join domain.  on client, can join domain fine, , without issue.  on server, ad adds computer entry client , seems well.  in client logs, see joined domain successfully, syncs time clock server, etc.  however, seems upon reboot of client, client loses contact server, , there error in log saying can't contact domain because there no logon servers service request.  have printers deployed in group policy, , never added machine, either.  time says can't sync server anymore.  ideas? can still ping server client , vice versa , there don't seem issues.  if disjoin client , add domain, works again until subsequent reboot (it seems).  help!

hi,

 

q: think problem might in group policy overriding dhcp?

 

a: said: manually adding record in forward lookup zone fix being able right click , 'manage' computer through active directory. personally, guess problem may not related group policy settings override dhcp setting.

 

since have verified settings correct due previous post, record of client still doesn't exist in forward lookup zone. name resolution issue.

 

troubleshooting steps:

 

1. may assign static ip address on client, , make point current dns server.

 

2. please run "ipconfig /all" on problematic client ensure dns server pointing correct domain controller.

 

3.  afterwards, can run following command on client check if can manually register ip address on dns server.

 

ipconfig /registerdns

 

q: can ping machine hostname , name somehow resolves. what resolving if there's no record in forward lookup zone?

 

a: think operation system tried resolve name using netbios. although have not configured wins server, clients can still use netbios broadcast resolve names in same subnet.

 

by default, windows server 2003-based, windows 2000-based, , windows xp-based dhcp clients configured request client register resource record , server registers ptr resource record.

 

could verify os version of problematic computer not register ip address in dns server?  if legacy os based-client, need configure dhcp server dns dynamic registration. if linux-based dhcp server cannot it, need use microsoft dhcp server or register ip manually:

 

for more detailed, please refer to:

meanwhile, please ensure dns dynamic update not disabled on problematic client.

 

please check disabledynamicupdate registry values in following keys not set 1 on problematic client.

 

hkey_local_machine\system\currentcontrolset\services\tcpip\parameters\ disabledynamicupdate

 

hkey_local_machine\system\currentcontrolset\services\tcpip\parameters\interfaces\<interface id>\ disabledynamicupdate

 

hope helps.
