hi,

we changed name of our wsus server , name did not replicate across domains.?
understood comments wsus server's new name registered in dns server in prod.net domain not in prod-web.net .

next

the name change on prod.net on 2008 correct , prod.net on 2003 incorrect. there 1 way trust between domains.
resolve issue, check required ports open on firewall

see ports requirement ad.

in addition,

active directory replication on firewalls

you may use portqryv2.exe, command-line utility can use troubleshoot tcp/ip connectivity issues.

also ensure below configuration dc , clients:

-->>multihoming domain controllers not recommended, results in multiple problems.
------------------------------------
1. domain controllers should not multi-homed
2. being vpn server , running rras makes multi-homed.
3. dns itself, better on single homed machine.
4. domain controllers pdc role automatically domain master browser. master browsers should not multi-homed

272294 - active directory communication fails on multihomed domain controllers http://support.microsoft.com/default.aspx?scid=kb;en-us;272294

191611 - symptoms of multihomed browsers
http://support.microsoft.com/default.aspx?scid=kb;en-us;191611

-->> ip configuration on domain controller:
------------------------------------------
1. each dc / dns server points private ip address primary dns server , other internal/remote dns servers secondary ones
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.

-->> ip 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 ws.

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

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?
