I'm having trouble connecting a Windows 7 computer to my Domain. I'm running a private network inside VMWare Workstation and have successfully connected a WinXP and Win10 machine to the network without any issues. However, this Windows 7 machine is giving me grief,
I'm running a Windows 2012 R2 Server that's my AD, DNS, and DHCP server. The Windows 7 machine is able to utilize the DHCP features and is autoassigned an IP address.
When trying to join the domain, I get the following Error:
An Attempt to Resolve the DNS name of a domain controller in the domain being joined has failed. Please verify this client is configured to reach a DNS server that can resolve DNS names in the target domain.
I've tried searching google for solutions with no luck. I've set up a Reverse Lookup on the DNS server, changed the Authorization settings, and a few other things without any luck.
Has anyone had this issue before? How can I get this computer to join the domain?
EDIT: Forgot to include that I'm able to ping the DC without any issues. I can also access the Windows Server from the Windows 7 machine via the
\\BNET-DC1 name. Network connectivity is fine, just unable to join the domain
EDIT 2: Trying to join with the DNS name rather than the NetBIOS name and I get this error:
Note: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt. The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "BNET.domain": 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.BNET.domain 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: 220.127.116.11 192.168.8.10 - One or more of the following zones do not include delegation to its child zone: BNET.domain domain . (the root zone)
ipconfig /all results from Windows 7 Machine: Screenshot of ipconfig
EDIT 4: ### SOLUTION ###
This is only a theory because all evidence has been removed. I logged into the one of the other machines in the domain and tried doing and
nslookup bnet.domain and it came back with an error. This meant that something in my DNS was corrupt. I demoted my DC and removed the DNS role. Then re-installed DNS and re-promoted my DC. This set things back to default and I was able to connect to the domain on each of the computers in the network.
A few quick things to check for anyone else having this problem:
Make sure your client and server are on the same subnet.
ipconfig /all is your friend. Use it.
Double check that the DNS Server address on the client is pointed towards your DC (if your DC is also pulling DNS-duty)
nslookup [DOMAIN NAME] to see if you have a valid DNS connection.
