Windows 10: Domain Controllers Synchronization Problems

Hello,I have a closed network with 4 Domain Controllers running Windows Server 2012 R2, DC1 DC2 DC3 DC4.By accident I have found that the baseline DC is the secondary DC DC2 and not the primary DC DC1 DC2 is the PDC but DC1 is the master of all other FSMO rules.Furthermore, in the Group Policy Management DC1 has the "SYSVOL Permissions are not in sync" error,and DC3 & DC4 are Sysvol Inaccessible.The Permissions on the Sysvol Folders seem to be identical, there are no networking issues that might cause this,and all the repadmin commands /syncall, /kcc, etc return successful.Are there

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

One more point... I am not sure if I posted this to the correct forum.. So if I was wrong and it should be in a different one..
PLEASE LET ME KNOW

 

UnattendedJoin error: failed to find the domain data (0x6e)

Thanks for the suggestion! I don't want to add a domain account, as this is a generic unattended install that will be used for all company machines. Do you think it's possible that the computer would join the domain if, instead of using UnattendedJoin in specialize, I used your steps but left out the specific account?

The other thing I was thinking was to use a generic account to allow the domain join during the specialize step. I added a machine password in the UnattendedJoin component, and instead of getting the error listed above, I got an authentication error, which makes me think I could probably do a secure join instead of the unsecure join.

Thoughts?

 

Domain Controller cannot synchronize with the Backup Domanin Controller

Dears,

I have 2 servers: Server 1 is Domain Controller and Server 2 is the Backup, they synchronize with each other. At the pass, 2 DCs run normally with windows server 2008 R2 for a long time (about 5 years). Recently, I upgraded the OS of 2 DCs to Windows server
2012 R2. After upgrading the OS, I upgrade 1 software (The Symantec Backup Exec System Recovery 9.x to Veritas System Recovery 18.x )at Server 2 (The Backup DC). After that, I found 1 problem: If have any change at the Server 1, the server 2 (The Backup)
can not synchronize the change but If have any change at the Server 2 (The Backup), the Server1
still synchronize the change.

Anyone can help me to fix the problem.

Thank you very much.
