nslookup returns wrong adapter

-

i asked question , i'm puzzled.

two servers, replication partners for vmware.  both have 2 adapters configured, 1 172.x.x.x address , 1 10.x.x.x address. (the 10.x.x.x adapters not cabled)  replication failing @ 6 pm work after tech manually ran , continue regularly scheduled throughout night. doing nslookup 1 server other server returns 172 address , 10 address.  co-worker said when failed, nslookup returned 10. address.

is possibly because both adapters set dynamically update dns?  replaced 2003 ad dc's 2008 dc's.  2008 dns work little differently 2003 did?  there random bind order changes if dns lookup? 

thanks clarifying not domain controllers. when first said "replication," assumed meant dcs.

fyi, if servers not dcs, don't have rras or dns installed, can safely disable registration in nic don't want register. can delete forward , reverse entries in dns.

you'll want set binding order of interfaces 1 want (the 1 on prod side) first in binding order. blog shows how part of steps.

it's not mystery algorithm, rather it's random. guess you've been "lucky" see wrong 1 resolved @ 6am.

an ad member linux bind server if linux server listed in it's dns entries in nic. ad, want ad dns servers listed host ad zone. if there else need resolve, can configure forwarder linux bind server on ad dns servers. way ad members query own dns insure ad works, , dns forward requests based on forwarding config.

in case, if may suggest, allow ad dns servers host primary forward , reverse zones, , configure secondary on linux bind server copy of zone 1 of ad dns servers. makes easier , more secure, actually, because if make zones ad integrated, have secure update option, can still configure zone allow zone transfers linux bind servers. , know, ad integrated zones, zones automatically appear on dc/dns servers, won't have configure zone transfers among them, nice feature.

Edit Group Policy

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 ...
