  1. I've been tasked with migrating a customer off of server 2008 R2 to Server 2012 R2. All FSMO roles have been transferred to the newly created Server 2012 R2 DC's and replication is taking place. Tomorrow, I would like to migrate dns off of the 2008 boxes. The scopes have replicated to the new dns servers, but how to I make sure the clients get pointed to the 2012 dns servers once I take the 2008 servers offline? I do have dns integrated into AD. I'm stuck at the "ensuring primary dns server" becomes my 2012 DC. Would the below powershell command set this across the domain? Set-dnsclientserveraddress –interfaceindex 15 –serveraddress (“xx.xx.xx.xx”,”xx.xx.xx.xx”) Any advice would be greatly appreciated. Thank to everyone!
  2. Hello All, I've been troubleshooting an issue with Name resolution between two separate active directory forests (trying to get a SCCM 2012 client assigned to a site, but I need to resolve this DNS issue first). There is a two-way trust setup, but something changed which is preventing a successful trust validation\nslookup\ping domain name. Here's some context and more detailed info: Forest/Domain A (a.local), Domain Controller A (DNS installed) - Conditional forwarder zone setup for "b.local" in DNS - can successfully ping b.local - can successfully NSLOOKUP b.local - DCA has two virtual NICs (private/backup) - Communication between other forests\domains works fine Forest/Domain B (b.local), Domain Controller B (DNS installed) - Conditional forwarder zone setup for A.local - Can NOT ping a.local - Can NOT NSLOOKUP a.local (2 second timeout message) - CAN ping backup IP address of domain controller (DCA) in a.local - DCB has two virtual NICs (private/backup) I have tried several ipconfig /flushdns, ipconfig /showdns, disabling/re-enabling the virtual nics and switching around of DNS IPs on the NICs, etc but i can't nail down the problem. It almost seems like network requests for "a.local" are never forwarded to the DCA server. I probably should install and run a network trace, but I don't have much experience with those apps. Anything come to mind by the information I've provided? I would really appreciate any troubleshooting ideas/advice as I'm new to DNS, especially with multiple network interfaces/ AD domains/etc..
  3. I have a situation that doesn,t allow me to add the DHCP servers to the DNSupdateProxy group for Dynamic Update to work correcly in DNS. We have credentials set in the DHCP IP settings and have option 81 setup with out the option for Name protection. The DNS records are getting updated somehow with the user account that we are using but it isn't quick and there have been complaints. Can DHCP still update DNS Dynamically with out the DHCP servers being in the DNSUpdateProxy Group? If not, How is the user account owning the record and updaing the account without the help of DHCP? We have a ton of DNS update failures in the DHCP log and the only ones that are successful are the new records that are created.

    DNS HELP PLEASE URGENT!!!

    I am getting the following error: The error was: "DNS name does not exist." (error code 0x0000232B RCODE_NAME_ERROR) The query was for the SRV record for _ldap._tcp.dc._msdcs.sage.dom Common causes of this error include the following: - The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses: 192.168.2.XXX - One or more of the following zones do not include delegation to its child zone: sage.dom dom . (the root zone) I demoted the older server from being a DC and now I am getting this error: how can i fix this?

I have 2 servers 1) Windows server 2008 R2 Roles Active Directory Domain Controller (GC) DNS Files services 2) Windows Server 2003 Roles DHCP Print Server DNS Domain Controller I want to move the following roles over to the Windows 2008 server ( DHCP, Print Services) and I want to wipe out the Windows 2003 server and upgrade to Windows 2008.
