Windows 10: Windows 11 periodically stops resolving domains.

I have been having an occasional moment where my Windows 11 system just loses the ability to process DNS requests from all applications. An IP ping is fine. I can even hit 8.8.8.8 with no issue. I try to hit www.google.com for example, and it went to 10.0.0.1... My router scope isn't in the 10.x.x.x network. So browsers, chat apps, remote apps all stop working.A fix is doing an ipconfig /release and /renew. While it fixes it, I'd like to find out why it is doing it in the first place.Windows is up to date and I believe all of my drivers are up to date.Thanks.

Question:- How to add client to domain from domain controller side?

Hi Guys,

-I have domain called lab.com created on virtual machine Windows Server 2008
-I have added a client machine Linux machine rhel6 to domain lab.com in /etc/host file
-I am able to ping DC from linux machine by IP and hostname .
But from DC I can only ping Linux machine by IP address and not by its hostname "rhel61.lab.com"

I don't want to add linux machine entry to DC's hosts file as it is DC so it should resolve it

But I wish to know what step or doings I am missing from DC side that I am not able to ping linux machine by its hostname.

Please suggest.

Thanks.

Step 1: If you have installed any third party security software, I suggest you to temporarily disable them.

Disclaimer: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other
software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Step 2: I suggest you to refer to the following article and check if it helps.

Raising the windows domain and forest issues?


hi,

I run a domain that was all 2003 r2 servers. I recently upgraded all my domain controllers to windows 2012 r2.
That went off without any problems.. Our trust relationships had no issues also.

My first step was to raise the Domain and Forest levels past 2003 to 2008. This went off without a hitch.
These are the features for raising the levels to 2008:

• Features and benefits include all default Active Directory features, all features from the Windows Server 2003 domain functional level, plus:
• Read-Only Domain Controllers – Allows implementation of domain controllers that only host read-only copy of NTDS database.
• Advanced Encryption Services – (AES 128 and 256) support for the Kerberos protocol.
• Distributed File System Replication (DFSR) – Allows SYSVOL to replicate using DFSR instead of older File Replication Service (FRS). It provides more robust and detailed replication of SYSVOL contents.

Forest Level Windows Server 2008

• Features and benefits include all of the features that are available at the Windows Server 2003 forest functional level, but no additional features. All domains that are subsequently added to the forest will operate at the Windows Server 2008 domain functional level by default.

My next step is to raise the domain and forest to 2008 r2, then 2012, and finally 2012 r2. I have been trying to find out exactly what I could expect from raising the Domain and Forest for each step.

The step involving 2008 r2 seems relatively a non issue. But getting the couple of new features seem very nice

Domain Level Windows Server 2008 R2

• All default Active Directory features, all features from the Windows Server 2008 domain functional level, plus 2 new features

Forest Level Windows Server 2008 R2

• All of the features that are available at the Windows Server 2003 forest functional level, plus the following features:

• Active Directory Recycle Bin, which provides the ability to restore deleted objects in their entirety while AD DS is running. <== New Feature very cool
• All domains subsequently added to the forest will operate at the Windows Server 2008 R2 domain functional level by default.

Here is my big concerns for the next raising of domain and forest to 2012.

Forest Level Windows Server 2012:

• All of the features that are available at the Windows Server 2008 R2 forest functional level, but no additional features.
• All domains subsequently added to the forest will operate at the Windows Server 2012 domain functional level by default.

Domain Level Windows Server 2012 R2: <=====Need to investigate more and why this post

• DC-side protections for Protected Users. Protected Users authenticating to a Windows Server 2012 R2 domain can no longer:

• Authenticate with NTLM authentication <==============(what issues may arise)
• Use DES or RC4 cipher suites in Kerberos pre-authentication
• Be delegated with unconstrained or constrained delegation
• Renew user tickets (TGTs) beyond the initial 4-hour lifetime

Will this affect my exchange anywhere users with remote access authenticating either clear of NTLM???
and what would/may not to work properly day 1 when I raise the domain and forest to 2012. I cant really find anyone that can answer a straight question.

Has anyone gone through this? what problems did you have, if any , if a lot???

Any thoughts and suggestions will be much appreciated??

thanks
