Hi,
Is there any other way we can give RDP access to Domain Controllers? Since, when i promote a server as domain controller unable to login to those servers. When i looked the GPO's applied to the domain controller OU, nothing related to that access permission. Is there any other way we can check the policy or some other settings related to this?
Thanks in advance.
Hello Team,

Hello Everyone,
I'm with a problem when i try deploy LAPS in my infrastructure.
I looked for the solution here but in my case it didnt solve.
So when i use the "Update-AdmPwdADSchema" the error appears:
"Update-AdmPwdADSchema: An Operation error occurred.
At line:1 char:1
...
+CategoryInfo : NotSpecified: (:) [Update-AdmPwdADSchema], DirectoryOperationException
+ FullyQualifiedErrorId : System.DirectoryServices.Protocols.DirectoryOperationException,AdmPwd.PS.UpdateADSchema"
I'm using the domain administrator account whitin the group Schema Admin.
I downloaded the LAPS from the official MS site and beforehand i installed and used the command "import-module admpwd.ps".
I'm using Windows Server 2016 and the firewall is disabled.
Anyone have this solution?
Thaks!!!
Hello tech world, I ran the following command on DC01 (however DC02 passed test RidManager), both are in the same site, both can talk with the Rid Master, all DC's ports are open, i.e 389,636,53,123,88,135,137,138,139,445,464,3268,3269
DCDIAG /Test:ridmanager /v
then got the following error:
Available RID Pool for the Domain is 64878 to 1073741823
FQDN is the RID master
DsBind with RID Master was successful

Hi Support,
I have remove the domain controller 2008 r2 and promote again but name is still showing and RODC unable to communicate with new Domain controller.
I have remove all the old domain controller from DNS and site & services and active directory pc but still when run the below command the showing old server name:
C:\Windows\system32>Repadmin /replsum
Remove the Old server TEST-LAB-DC-01 ip address 10.0.045
Active Directory Domain Services did not perform an authenticated reHi to all
In our domain we have 2 DC servers. Windows Server 2003 R2
The second one is also a file server.....
Today when i came in my office a hear a lot of complains from some of our user that is unable to open the map drive of our file server. When i see that i was unable to login in our Pri DC i make a check and i see the server is off. After i power on the server everything works as expected.
I would like to know why the second DC does not authenticate the user.
The current configuration is very old and i don't know a lot of things from 2003 Servers.
Please help me to find a solution with as details as possible.
Thanks and regards.

We have a forest trust between A and B.
Clients in A have accounts in B and access resources in B using those accounts.
Nothing has been granted to B to access A.
Our PDC is logging No_Client_Site authentications for all kinds of clients from B. I checked the security log and couldn't match any audit success or failure to the Netlogon.log entries. So I'm unclear why these clients would even be touching my domain controller. Is this normal?
Thanks!
This is a strange one. It keeps happening...
I have a total of 8 Domain controllers, this only happens to one specific site and one specific child domain.
Server 2012r2 and Server 2016. forest level of 2008r2
the DC will be working fine, handling all requests etc. However when you reboot, you can no longer log in to console.
This is happening on physical and virtual machines.
If I disable the vm's nic in VMware, start the machine up with out being connected to the network, I can log in. Then I turn the nic back on.
The other symptoms are when the machine reboots it uses all ram assigned to the VM if it is going to fail.
It will get to 'waiting for ADDS', then reboot again.
When it does come up, I can enter my password (or any password) and it won't allow me in.
I disconnect the nic, reboot, it allows me to log in and turn the nic back on.
Some of the things I'm seeing in event viewer
The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (CreateSession).
I'm trying to create an OU using the command prompt.
I am running the following command in ntdsutil partition management:
create nc DC=xxx,DC=xxx,DC=xx NULL
It gives me the error:
ldap_add_ext_sW error 0c44(68 (Already Exists).
When I check the partitions in ADSI Edit, I don't see the partition there. So I can't delete it because it's not there, but I can't create it because the system is saying it already exist.
Has anyone run into this issue before? Any ideas on how I can get this OU created? I have to create this specific OU for one of our programs to work.
Running on Windows Server 2012 R2
Thanks,
Hi All,
We have around 8 AD servers along with 4 multiple AD sites running 2008 server. More Than 4500 users with multiple subnets.
All the AD servers are running some application and services like DNS, DHCP, ADFS, Attendance file system, Ad Audit Plus.. etc.
Active Directory is synced with cloud. Currently we are facing a lot of issues like replication, authentication issue, downtime issue, application down issues.. etc.
In our concern kindly clarify and explain below:
1. Best practices for AD with multiple sites along with DNS, DHCP services and applications.
2. Whether we can implement with old servers or we need to migrate the servers from old to new.
3. How to avoid AD Replication and user authentication latency issues.
4. Ho do we overcome application latency issues and downtime issue.
5. How do we set Site and services topology for multiple site replication.
6. Is it enough Additional Domain Controller or we needing Child Domain.
7. Is it the better choice rather branch offices in RODC servers.
8. Best Practices for Active Directory Infra.
9. How do we set FSMO roles along with multiple sites.
10. Domain Controllers capacity for users.
Thanks,
Leenas
We have a file folder (FolderA) with inheritance enabled. UserA is the owner of the folder. The AD groups associated in advanced security settings like this:
Type Principal Access Inherited From Applies To
Allow AD Group A Modify FolderB This folder, subfolder and files
Allow UserA Full Control FolderB This folder only
Allow Creator Owner Full Control FolderB Subfolder and files only
Allow Administrators Modify FolderB This folder, subfolder and files
The checkbox "Only apply these permissions to objects and/or containers within this container" is NOT checked. I don't find that checked up the chain either.
When UserA drops any files in this FolderA, the security on them is limited to UserA and Administrators. None of the users in AD Group A have any access to the files. I am certainly not very experienced with NTFS permissions, but that doesn't seem correct. When any other user that is a member of AD Group A drops files into FolderA, inheritance is working.
Any ideas what might be wrong?
We got some issues with Applocker and Adobe XD CC, when we block open Windows Store via GPO it works windows store can't open but when we install Adobe XD CC it also cannot open too it alert "This

What should we do for these issues?

Hello!
Could you please someone help me on this:
I need to create an AD account for a helpdesk tech that he will be able to do some basic stuff on the active directory. Like a reset or an unlock. Is there a default security group (but not the domain admin) that it has this ability?
And how i can add this account to the local administrators group for every pc inside the company. I think it can be done with a GPO?
Thank you in advance!

I'm trying to follow this article but I'm doing something wrong and or misunderstanding what I'm supposed to do. https://www.jacksontechnical.com/article.htm?id=57
I'm trying to replicate between two 2016 servers in different domains. Perhaps I'm trying to modify the wrong objects or looking under the wrong names for services in 2016.
I tried setspn but failed
setspn -S "Hyper-V Replica Service/hostname" host1
or
setspn -S "Hyper-V Replica Service/host1" host1 or with the domain extension
Call to DsGetDcNameWithAccountW failed with return value 0x00000525
I can get to the other by name by ping or smb file share.
I'm trying to find the AD settings in the link above in 2016 and must be looking in the wrong place. I'm in active directory users and computers. I went to advanced view. I selected the host server properties. I have no idea how to add Microsoft Virtual Console Service or any of the other services listed there. I have found a few similar articles but can't find something I can follow on how to add the service.
Hello,
linux users use Active Directory for authentication and use samba server to get own profile.
1. User enter AD credentials on Linux-PC-01
2. AD approving and allow enter to computer. User getting kerberos ticket.
3. Then on this PC internal service try connect to samba and ask access to profile
4. Samba validate user through AD
5. AD approve and user start mount and copy profile
The problem begins i user logon on other computer Linux-PC-02. He pass authentication successful (steps 1-3), then try mount profile. Samba ask AD and ADSOME TIME answer, - "Do not trust for this user". As a result samba deny access to profile, and user have local (temp) profile.
After few hours, if re-try mount profile the problem is not arises.
P.S. In organization two domains, in each domain own samba and client. In A domain there no problems, but in new domain B the problem is present. Some thin options are present in "A" AD domain (previous administrator configure it), but this options are lost in "B" domain.
Hi Guys,
I have a Domain with one Domain Controller. In the past the domain had an SBS 2008 Server. The server has been removed and replaced with a new DC (DC-A, Win2012R2 - Data).... long time ago (Just in case its relevant, i dont know how exactly the SBS 2008 was removed by the old admin)
I have set up a new server and promoted it to a secondary DC ("DC-B", also Win 2012 R2 Datacenter).
I promoted the server a week ago, so all replications should be done.
When I open the DNS Manager of the first DC-A and add in the MMC-console the secondary DC ("DC B") then all looks fine. All zones (AD integrated) are fine and filled with DNS entrys.
DNS-Manager on "DC-B" list all zones, but in the zones only the nameserver entrys are present.
When I open the "DC A" over the MMC of "DC B", then also all zones are listed, but only the namserver entrys are present.
So I checked the replication status. All fine!
No errors... i double checked it with the Microsoft "AD Replication Status Tool".
When I open on the "DC B" the AD computer & server or AD location & service all changes getting replicated fine.
Also creating a new AD user or a new AD-Site location works fine.
Even when I change a password von "DC B", the changes are replicated to "DC A".
So it seems to work fine.
But my DNS Zones on "DC B" are always empty. DNS resolving works like a charm (Also tested different network DNS settings on both DC´s... primary DNS 127.0.0.1 / DC A / DC B /... and so on and rebooted many times)
DCdiag /TEST:DNS also fine.
When I create a new AD-integrated forward zone or DNS entry its not replicated to the other server (tested from both sides).
The eventlog on DC-B tell me "Source: DNS-Server-Service, ID:4". So the DNS server tell me the loading, replication of zones was successfully.
So I thought, bad luck and tried to demote the server "DC B"... this failed.
In DNS Manager I found "Forward-Zone -> Domain.local -> _msdcs" only the nameserver of the SBS 2008 server, I changed it but this solve not my problem.
In the eventlog I just see errors regarding to PKI (remains of the old SBS 2008), but I think the certificates should not effect the AD-Integrated DNS-Zones (no DNSSEC in use).
Source: CertificateServicesClient-CertEnroll - ID 82 and ID 13
At this time, I have no idea what to do next.
I could force a removal of the new DC-B, but what if this happens again by the next promote?
When the replication works, the DNS AD-Integrated zones schould be also replicated without problems. What could cause this problem?
Hopefully someone can give me a hint.
Kind regards,
Matthias
Hi All,
I need to know what is the Bandwidth recommendations form the Sites "same country" to head office site "distance 400 KMs max" :-
Dear All,
Recently we have started facing issues while logging to server
Authentication (Login or challenge) has failed
We have 3 DC. All are replicating fine , so far I have seen any replication Errors.
One one of affected server getting
he Kerberos client received a KRB_AP_ERR_MODIFIED error from the server rjopsvpwflmap01$. The target name used was RJOPSVPWFLMAP01$. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Ensure that the target SPN is only registered on the account used by the server. This error can also happen if the target service account password is different than what is configured on the Kerberos Key Distribution Center for that target service. Ensure that the service on the server and the KDC are both configured to use the same password. If the server name is not fully qualified, and the target domain (ROYALJETGROUP.COM) is different from the client domain (ROYALJETGROUP.COM), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server.
I have reset the SPN also from DC
Replicated the DC, still the same issue
Just to update we have PAM software installed on the servers (Centerfy)
Please help me to get this sorted out.
