DNS Server Crashed / How to join new server to domain?

-

hello all,

we have issue in old environment, without backup/restore posibilities.

the environment has 2 w2k servers, both of them domain controllers, , form sql cluster (yes, against ms best practices). there aren't other server or domain controller in domain.

- server1: domain controller + node of sql cluster.

- server2: domain controller (with fsmo roles) + dns server + node of sql cluster. 

 server2 crashed couple of days ago, , operating system lost. unfortunately haven't kind of backup :-(  . server 1 keeps working. there's not dns server, guess server1 still works due dns cache (but not sure that).

now server2 has been reinstalled (only operating system), cannot join domain because of dns problems (dns server cannot found).

we need join server2 domain in order cluster node again. steps should follow?

we thought seizing fsmo roles in server1 (with ntdsutil), , create dns server on server1 (maybe populating info see on ipconfig /displaydns).

any ideas?

thanks in advance.

your last assumption correct.  seize of roles on server 1.  also go ad sites , services , make sure server running global catalog server (gc).  then install dns role on server.  create ad zone on server. point dns client settings on server 1 point dns.  restart netlogon service necessary records can updated in dns zone. 

after this, report more information if needed.

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 ...
