Windows 10: Windows server 2008 dc/dns issues

I’m investigating an issue with a windows server 2008 DC/DNS. Will not allow me to join a new computer to the domain. What would be the reason why the ForestDNSZones and DomainDNSZones are not showing in DNS? Only thing visible is _msdcs. Note that this is the only DC/DNS Server on this small network. I’m at a loss here.

DNS server causing problem

Hi Andrea,

DNS is a server that translates websites' addresses so that browsers can connect to them. If the addresses become outdated or the server has issues, problems and DNS errors occur. For us to provide an accurate solution, we would need you to answer the following
questions:

• Which build, version and edition of Windows is installed on your computer?
• What changes have you made to your device before this issue occurred?
• Are you experiencing the same issue regardless if you are trying to be connected to a wired or wireless connection?

For initial troubleshooting, we suggest deleting the DNS cache. This can refresh the DNS files and settings on your PC. Follow these steps to delete the DNS cache:

• Using Search type Command Prompt.
• Form the search results, right click on Command Prompt (Desktop app) and then choose Run as administrator.
• In the Command Prompt window, type ipconfig /flushdns and then hit the Enter key.
• Once done, restart your computer and then check if the same issue persists.

We are looking forward to your response.

 

DNS SERVER NOT RESONDING

Hi Rita French,

This issue often occurs when the DNS settings are incorrect. I suggest you to perform the following methods to troubleshoot the issue.

Method 1:

I would recommend you to change the Preferred DNS server and check if it helps.

• Press Windows + R keys to open Run window, type
  ncpa.cpl and press Enter.
• Right-click on the connection that you use for the local connection, and then click
  Properties.
• Click to select Internet Protocol Version 4 (TCP/IPv4), and then click
  Properties.
• In the Internet Protocol window, let's change the Preferred DNS server to
  208.67.222.222
• Click OK twice to complete the modification.

Note: If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220.

Method 2:

If that does not help, try to flush the DNS. Follow these steps below.

• From Start screen, type Command Prompt.
• Right-click on Command Prompt and choose Run as Administrator.
• Type: ipconfig /flushdns and press Enter.

Note: The ipconfig /flushdns command provides you with a means to flush and reset the contents of the DNS client resolver cache. During DNS troubleshooting, if necessary, you can use this procedure to discard negative cache entries from the cache, as well
as, any other dynamically added entries.

Hope any of these methods help!

Kind regards,

Leon

 

Demote 2008 DC - access denied

Hi,

I'm working on server updates, updateing my companies DCs from 2008 to 2016. I have the replacement server built but unable to demote the old server from AD. When I start the proccess it stuck of:

The operation failed because: Active directory Domain Services could not configure the computer account (dc name) on the remote Active Directory Domain Controller (secondary DC name). "Access is denied"

I been searching through the internet for result but couldn't find the right one so far.

I was checking all the suggestins from this link: Access Denied " During Demoting Domain Controller "

But none of them seems to be the issue. The account I use has all the necessary rights to perform this but still failing.

I would appreciate any help or suggestion. Thanks in advance.
