Dear All,
I am struggling to FIX my Primary DC, the issue seems to related to the DC Replication. I have searched a lot on google, the Popular solution I found is to Seize the Operation MASTER and Cleanup Metadata.
Secondary DC is working fine and Operation Master is available, I just wanted to know after doing the above can I still manage to get my DC 1 Back? as there are a lot of solutions available on the internet, can someone tell me what is the best Solution to Fix Operation Master on the DC1
Quick Help will be highly appreciated
Thanks and Regards,

Dear All,
We have to plan and Design DC 2016 for 500-1000 Thousand Users, I need Proper Guidelines to set it up.
1. How many Domain Controllers do we require for the load Balancing or Failover Purpose?
2. How many DNS servers do we require for such amount of USERS, we would have a 500+ WIFI user using the same DNS Server.
3. I need Proper Servers Infrastructure Guidelines and Best Practices to Setup this environment.
Hello Team,
We have DC and ADC , DC and ADC sync properly after change the password user not able to login , user able to login with OLD password are reset the password with SAME password . DC and ADC Sync successfully .but user not able to login .

After having demoted and removed one of two domain controllers I cannot add any new servers to the AD. Both the DC and the server I am trying to add is running Server 2016. I have enabled netbios over TCP/IP. The new machine has only the DC as DNS, I have started the netlogon service and the DC passes all teh dcdiag tests. The new machine can ping the DC and vice versa. I am completely stumped.
Have to migrate a lot of servers from one domain to another over an extended time period. On each server, there are services running with the same domain user account. Have read the ADMT Migration guide and https://blog.thesysadmins.co.uk/admt-series-6-service-account-migration-wizard.html, but can not find an answer to the following scenario.
1. Run the ADMT Service account translation wizard, specify server1 and <olddomain>account1 which is used for the service.
2. Run the ADMT User Migration Wizard and migrate <olddomain>\account 1. This procedure works without any problem. The <olddomain>\account 1 is migrated to the new domain, and ADMT then presents the option to change the SC entry of server1 from<olddomain>\account1 to <newdomain>\account1. This also works fine.
3. After some time, I run the ADNT Service account translation wizard again and specify server2. Server2 has services which run under the same account <olddomain>\account1.
4. Here the problem starts. When running the ADMT user Migration Wizard again and choose the already migrated <olddomain>\account1 and specify the option "do not migrate source object if target object already exists", ADMT stops at this moment and doesn't offer the option to change the SC entry of server2 from <olddomain>\account1 to <newdomain>\account1.
What is the correct procedure to change the SC service entries on all servers with ADMT? We do not want to touch existing servers and change service accounts a long time before the migration. And we do not want to migrate the <olddomain\account1> again to the new domain. Because ADMT does not migrate passwords for service accounts, we had manually set the password of <newdomain>\account1 after ADMT has migrated this user.
Thank you all in advance for any helpWe have Certificate Services deployed in our 2008 R2 AD infrastructure. We have a GPO set up in limited production that allows workstations and servers to request certs via a custom template. All servers and most workstations have only requested one cert, but I have a few workstations that have requested multiple certs and I can't figure out why. Many of the workstations with multiple certs have only two, but I have one that currently has 12. All workstations are subject to the same GPO and cert template, the name and display name for the template are identical, certs are published in AD, and the "do not automatically reenroll" option is selected in the template. GPO settings are listed below. What am I missing?
Automatic cert management: Enabled
Enroll new, renew expired, etc.: Enabled
Update and manage certs that use templates from AD: Enabled
A few weeks ago the domain controllers in our Lab domain was attempted to be migrated from FRS to DFS. The domain is at Windows 2008 R2 functionality level and the DC's are on Windows 2019. When the migration was initiated with Dfrsmig this error appeared every 5 minutes when it tries to migrate SYSVOL:
DFSR was unable to copy the contents of the SYSVOL share located at C:\Windows\SYSVOL\domain to the SYSVOL_DFSR folder located at C:\Windows\SYSVOL_DFSR\domain. This could be due to<g class="gr_ gr_222 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins replaceWithoutSep" data-gr-id="222" id="222">lack</g> of availability of disk space or due to sharing violations.
Additional Information:
Sysvol NTFRS folder: C:\Windows\SYSVOL\domain
Sysvol DFSR folder: C:\Windows\SYSVOL_DFSR\domain
Error: 367 (The process creation has been blocked.)
Replication between the two domain controllers <g class="gr_ gr_265 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar multiReplace" data-gr-id="265" id="265">were</g> working without any issues. I've tried just about everything to fix the problem, adjusting permissions on the folders, running the Robocopy command manually (which did copy all the folders and files without error), deleting all GPO's not being used, running DCGPOFIX, removing all DC's except one, even performing a System State restore to a new DC (with an auth restore of AD and Sysvol). Rolling back the migration and starting again.<g class="gr_ gr_1532 gr-alert gr_gramm gr_inline_cards gr_run_anim Style replaceWithoutSep" data-gr-id="1532" id="1532">Nothing</g> has corrected the issue.
Has anyone seen this error or have any suggestions?
The domain holds no important data, there has been no exchange or other AD-integrated application.
How do I blow the forest away so I can remove and reinstall all the roles (AD roles,DNS,DHCP) as to create a fresh domain, if possible without reinstalling the server operating system?
Edit: To clarify the domain controller is the only one in the forest and domain.
Hi there,
I'm trying to use Get-ADUser for the following purpose: Checking if SharePoint users even exist in their Active Directory. Now there's only a one way trust between domain of SharePoint servers and SharePoint users (e. g. PeoplePicker had to be configured for that reason). There also is a strict firewall between these domains. What am I able to do is to use LDP tool to connect via port 389 from the SharePoint server to the Active Directory. This at least was opened for User Profile sync...
However, I'm trying to connect with a different user and naming the foreign server, of course foreign domain is one way trusted and name resolution works:
Get-ADUser -Server dc1.foreigndomain.corp:389 -Credential FOREIGNDOMAIN\adreaduser
In a full trusted environment without any firewall that works like a charm, unfortunately not in my scenario. Could you please help me? Which additional ports are needed? Does this work with one way trusts at all? Which other possibilities do you see for reaching my target which actually was to check SharePoint identities against the Active Directory?
Thanks in advance!

Greetings,
First of all, sorry, english is not my mother tongue.
In my company, we are currently preparing an AD migration from a domain to another. The other domain is available and i'm preparing the migration by recreating the OUs in the new domain.
To do so, i used the tool "LDIFDE". Everything worked fine, but i noticed that some OU's were not created by the ldifde command.
After some investigation, i concluded that the not created OUs were those who had avery long distinguished name.
In our current domain, we have a very long active directory tree. Some OUs (those not created by ldifde) have, for example,312 characters.
Currently, we do not have problems with those OUs, but does anyone know if that DN lenght can cause troubles ?
Is there a limitation recommended by Microsoft ?
Thanks, regards.
Hi I have a question regarding my DFS.
I started DFS replication between 2 servers about a week ago. The sending server has 475GB to send over
The receiving server has a 1TB partition dedicated. I can see that on the receiving server has 344GB used up. When I look inside the folders I see that the entire folder structure is present however everything seems to be empty. When I go to properties of the folder it is telling me only 20GB is used. I was getting a few errors regarding staging quotas that were set too low. I ran 2 commands which told me that the recommended size was to be 71GB which I set it to.
So I am trying to understand why I don't see anything in the receiving server yet? Is it simply not finished yet?
If it is not finished how can I see what is going on. I've scoured the Internet to find some kind of tool that can tell me verbosly what the DFS is doing but such a tool does not seem to exist. I am looking for something that says something to the effect of
Sending server is sending XXX file at XXX% or DFS replication is at XXX% complete.
Basically, anything that can give me a little information as to what exactly is going on, there doesn't seem to be much information as to what the DFS is doing, how much bandwidth it is consuming, resources..ETC..
Thanks!
I would like to verify various modules within our network. Active Directory Certificate Services seems to be the ideal way to do this.
Is there a charge for creating these certificates with AD CS? Any of the modules will be used only within our Active Directory domain...
Hello is there a way to manage azure ad GPO without having to spin up a VM in the azure cloud?
Can i use one of my on-premise systems?
i've created an OU higharcy and delegated access to a group with full control over all objects and descendant objects. Why cant a member of the group with delegated access rename a domain joined computer in the OU? i've verified the group is local admin on the server and even created a second delegation for the write all properties of descendant computer objects in the OU. I can see in the security setting on the server object all of the settings are as expected. there are no deny's in any of the settings on the OU. Could there be a GPO i'm not thinking of that is restricting this?
i've gone through multiple pages on technet looking for answer that isnt local admin / write all properties on the computer object.
thanks,
jason
I've been working on a DCPromo issue for about 6 months that I can't seem to get around. Some of my specific details are a little fuzzy at this point since it's been so long but I tried the process 3 times in the last 24 hours & I still get a failure.
2016 servers were RWDC & I demoted them & then tried to DCPromo as RODC. I continuously get these results:
The operation failed because:
While promoting Read-only Domain Controller, failed to replicate the secrets from the helper AD DC.
"The replication operation failed because the target object referred by a link value is recycled."
I have tried deleting any related AD recycle bin records short of just deleting everything, which I'm not doing. I'm searching by date, by server name & by "KRBTGT_" & deleting anything I find but the issue persists:
Get-ADObject -IncludeDeletedObjects -Filter {(IsDeleted -eq $true)} -Properties * -Server domaincontroller.domain.com | Where-Object {$_.DistinguishedName -like "*krbtgt_*"} | Select-Object Name,DistinguishedName,WhenChanged | sort whenchanged
Get-ADObject -IncludeDeletedObjects -Filter {(IsDeleted -eq $true)} -Properties * -Server myDC.mydomain.com | Where-Object {$_.DistinguishedName -like "*xxxxxx*"} | Select-Object Name,DistinguishedName,WhenChanged | sort whenchanged
Get-ADObject -IncludeDeletedObjects -Filter {(IsDeleted -eq $true)} -Properties * -Server myDC.mydomain.com | Where-Object {$_.WhenChanged -gt "7/17/2018 4:00:00 PM"} | Select-Object Name,DistinguishedName,WhenChanged | sort whenchangedI've also waited over 30 days between attempts (after deleting the recycle bin items) - no good!
The only way around it is to promote as an RWDC again.
Any suggestions would be appreciated.

Hello,
After setting up a brand new forest (dmz.example.com) a one-way trust was created with a trusted domain (example.com), and with brief testing it looked to work. But then I needed to rename the only domain controller, and now there is odd behavior from
the trusted domain, where my test client cant access the trusting domain.
From a client when attempting to access network share \\dmz.example.com a pop-up comes up and request login, with error "The system cannot contact a domain controller to service the authentication request. Please try again later". But I can ping the domain controller and the domain name.
This is a one-way trust where dmz.exmple.com is the trusting forest and the example.com is the trusted forest. and clients on the example.com get a pop-up when attempting to access \\dmz.example.com.
Any thoughts?
Thx
Robert
