so I did an install of Windows Server 2008 Enterprise on a spare system i have and configured it for a local domain (xxxx.local). Now my issue is, if I use my home router (192.168.1.1) for a default DNS, it does not pick up the domain controller. But if i configure the IP of the system for the DNS to be the DC (192.168.1.15) it picks up the domain and everything works like candy and puppies. But now I have another issue, I cannot connect to any other system on the network (which is a problem considering I have another machine that houses my SQLServer 2012 for my testing), which I need to be able to do. Is there a way to configure the DNS of the router to pick up on the domain controller instead of using the domain controller as a DNS within itself? Or at least get the DNS service on the DC to show other systems on the network?
I never set a secondary DNS for the server, so it could never reach out to the local network. After setting a loopback for the primary and the router's ip address as the secondary dns, i can now see all the other computers on the network.

I am joining Linux and Windows instances to an AD domain (). The machines are joining fine to the domain and I can use ssh/RDP using the AD credentials to login to the machines post domain join.
I can also get all the computer objects (host names) by running Get-ADComputer -Filter * on a windows server and providing the domain credentials. The issue is that, the host names for Linux based computers are not resolving to an IP address. Whereas all Windows hosts are resolving fine.
nslookup <windows-host> is returning host's FQDN and the IP address.
nslookup <linux-host> is returning Non-existent domain.
P.S: All these resources (windows and Linux hosts) are in the same network, using same DHCP/DNS server and can communicate to each other with no issues. Also I can resolve and connect to the AD domain from all these hosts
Any idea why this could be happening and how to resolve this ?
My use case is to get the IPs of all the computer objects in my AD domain.
Normally when using DHCP Windows will attempt to register its own A and possibly PTR records in the configured DNS, not sure about Linux. You may configure your DHCP server to update DNS for the clients (instead of leaving it to the clients themselves), i.e.:
To configure a DHCP server to register and to update client information with its configured DNS servers, follow these steps:
Open the DHCP properties for the server
Click DNS, click Properties, click to select the Enable DNS dynamic updates according to the settings below check box, and then click Always dynamically update DNS A and PTR records.

I make a web site to my local. I set bindings local.com and www.local.com. I add hosts xml to
127.0.0.1 local.com
127.0.0.1 www.local.com
So, I can connet on my pc like
local.com,
www.local.com,
192.168.1.35
But another pc on my network can't conenct with friendly name
www.local.com,
local.com,
But same pc can connet with ip
192.168.1.35
How can that another pc connect with friendly name ?
IP Addresses are the numerical identification for each device on a computer network.
Named Addresses invented, because remembering each device Address's turned to a difficult job.
So someone must know's which names must be converted to which IP Address.
DNS Servers are responsible to do this translation. But you done that locally. Actually you don't have a DNS Server on your local System, So you can't tell to others that "WWW.Something.COM" is my Address.
If you didn't connected to the internet, you must establish a DNS Server or done this task manually in all clients:
https://helpdeskgeek.com/networking/edit-hosts-file/
Running a DNS Server is another task. you can search for DNS Server applications like https://simpledns.com/ or you can setup a DNS Server using Windows Server. for both scenarios you need to tell to your clients to add your DNS Server Address to their network Adapter settings.
or If you are connected to the Internet, you can Use a NoIP to register a free Address:
https://www.noip.com/
you then need to download an application (In Noip.com) to monitor IP changes, it will monitors your IP address and it changes and then tells to NOIP.com to translate your address into your current IP address.
Actually NOIP will registers your address globally around the Internet network and each one who can access to the internet is able to reach to your address.
I'm going to host a web site in one of my computers toaccess it from the another computer. (Same local network) This what I have done so far.
Step 1 : Host the web site in IIS.
Step 2 : Using "Edit bindings" I changed the host name.
Step 3 : Then I changed the host file located at "C:\Windows\System32\drivers\etc"
192.168.8.100 mylocalhost.com
Step 4 : Turn off both private and public windows firewalls. (I know this is bad. But for now its fine. I can add inbound rules after resolving this issue)
I try to access to the url http://mylocalhost.com:8082 using hosted environment. It is success, but when I try to access that url from the other computer(in the same local network) it cannot be access. Without the above binding name (mylocalhost.com), I can access to the web site using http://192.168.8.100:8082
I want to access to the website using a url with any computer/mobile device connected to the local network. Can anyone show me a direction to resolve my issue?

Your problem is step 3 - your assumption that the host file on a single client computer will apply to all computers on your network. You need a server of some description for the behaviour you describe.
A hosts file is only used by that single computer to resolve or override dns. Each computer has it's own file and there is no default way of sharing this file with other computers on the network. Your choices are:
Add the host file entry to each device.
Setup a DNS server. your router might support this, and is likely providing the DNS server to your clients via DHCP so no additional config would be nessersary. Just login to its web interface and configure the dns name. If your router cant do it for you you would need a DNS service running on one of your computers and then configure either your routers dhcp/dns to use this new DNS service, or manually configure all clients to use the new DNS for their DNS resolution.
Setup an active directory server and join all your pcs to the domain (setting up AD includes a DNS server).
Some Public DNS providers allow you to specify a private ip in public dns. So assuming you owned the domain example.com you might be able to create an A record my.example.com for your 192.168.8.100 ip address. This would be public, but only devices on your private network would actually be able to connect to your server (ie different physical computers/networks that happen to use the same internal ip).
I have just taken over as a developer for a company. They host their development site on Rackspace. When I arrived, this server was spun down. Upon bringing it back up, I discovered that the IP address of that server points to the live website. There must be some kind of forwarding in place (I assume that it is through Rackspace) that does this. How can I fix this? I searched for settings on Rackspace to no avail. I would like to be able to access this dev site at least through the direct IP address until the network admin reappoints the develoment domain name to proper IP.
I'm guessing that you mean the live website domain routes traffic through to this server? Off the top of my head, you either have DNS load balancing in place - so an A record on your domain matching the IP address of the powered down machine OR you have a load balancer within rackspace that is routing traffic to it.
I have two Active Directory servers performing both authentication and DNS.
One server is 2003 and the other is 2008. It is my understanding that there is no primary Domain server in this scenario and that everything will replicate from 2003 to 2008 without issue.
I have a 3rd virtual 2008 server which has been preforming DHCP for over 2 years without a problem.
It is now appearing that I cannot properly authorize DHCP (Red downward arrow).
When I attempt authorization, I do not get an error. It simply does not function and appears to not be authorized. I also tried netsh for authorization.
I have an error in the logs of the DHCP stating:
"The DHCP Service failed to see a directory server for Authorization"
One change that was made recently was that I tried to revive the old physical DHCP server for performing another service. I changed the IP and the Computer name before I networked it. I have since turned it off, but I believe that this is when the problem began.
What is the problem?
Additionally, are one of the AD servers more primary in the authorization of DHCP, or are they of equal authority?
Thanks
Note: I have removed all outdated entries regarding DHCP from DNS.
Also, forest functionality level is set to Windows 2000, though we have nothing on our network older than XP.
Your first domain controller in your network is the "primary" domain controller. The primary domain controller keeps 5 FSMO roles of the entire Active Directory forest.
In your case, I think there might be some problems with DNS. Most of these types of problems were caused by DNS. You can try to use DCDiag utility to test the connection and DNS configuration from both domain controllers.
After fixing your DNS, you might want to restart the Net Logon service on both Domain Controller to refresh the SRV Record.
In the worst case that it happens to me, I had to dis-join the DHCP server (standalone server) from the domain, and join it back it, re-authorize it with AD.
