Hello Expters,
We have multiple 2016 Domain Controllers
We have demoted one DC from GUI and it was successful , But after removal of DC , this DC still shows in Sites and Services .
So , any Idea why its not deleted from Sites and Services ,
Did I miss any steps for demotion ?
Thanks for your help.
Thanks , Prakash ,Please Note: My Posts are provided “AS IS” without warranty of any kind, either expressed or implied.
In domain forest,it a few sites, how can a client ping the domain name of domain, DNS will return only dc of local site but not dc of external site?
For excample, I have a AD: A.com, and two sites: Site A and Site B.
Site A have DCs: DC01.a.com and DC02.a.com, Site B have DCs: DC03.a.com and DC04.a.com.
AD replicate between DC01 and DC03 ad bridge. other machine in Site A can't connect to Site B, the same for Site B's machine.
client of Site A, try ping a.com, it will only revert DC01 and DC02 IP Address.
Is that feasible？ If yes, how to do?
Hello everyone,
I have a domain on servers 2019 with forest functional level and domain 2012.
I have tried to join XP client computers to the domain, but it gives me "internal error".I have enabled SMB1 on the DCs and it still doesn't work.
Would it be possible to add those XP computers in the domain?
Thank you.
I am planning a test to handle an application with a domain user under the domain environment.
I don't always use "domains" in my development environment Install Windows Server 2016 on one computer We have set it as an Active Directory / Domain Server.
Connect this and one client machine (Windows 10) with PtP I want to make this client machine a machine belonging to the domain.
(Finally, register the domain user on the server side, Even if the user is not registered on the client machine A domain user, can use the application. It should have been implemented, but the environment is set for the demonstration experiment.)
!! However, this client machine cannot register the domain.
Control panel → system → Computer name, domain and workgroup settings → Change settings → System properties (computer name tag)
→ Click Change to change the computer name or join the domain → Click [Change]
Or
→ Click Network ID to use the wizard to join a domain or workgroup → Click [Network ID]
I get an error if the domain I configured on the domain server is not found.
The NetSetup.LOG generated in the Windows \ debug folder will have the following results:

Looking at this log, it says "trying to find DC in domain 'MYDOM'". It seems that the domain controller is kicked out because it is not in the domain'MYDOM ',
Before that
it say "NetpCheckDomainNameIsValid [Exists] for 'MYDOM' returned 0x0",
This check requires a domain controller, which seems inconsistent.
Until now, even if you set up a domain in such a test environment It would have been nice to set the default settings according to the wizard without thinking about it. I'm having trouble finding the way to deal with this time, which one is the policy, Or it would be helpful if you could give us a reference such as a reference site or literature.
Hi,
Is there any solution (e.g. for MSP) to connect an external o365 tenant with customers' on-premise AD?
It would be great if the MSP's tech guys could authenticate with their o365 accounts in customers' on-premise servers.
Just started at new company and doing AD Health Checks on Forests.
Found out in the DEV Forest Root that it is not replicating to the Child Dev Domain.
Running repadmin /showrepl I see that the Forest DC's are replication fine, but failures on Child DC's. Using Get-ADReplicationFailure from any Forest DC, I get "Either the target name is incorrect or the server has rejected client credentials.
Running these commands from Child Domain shows replication is fine. No Errors.
From the Child DC's, I ran nltest /sc_query:ChildDev /server:AllForestRootDC Names.
Every DC response from Forest DC's returned Success, except for DC05, from every Child DC, I got "Error_NO_LOGON_SERVERS"
Running nltest sc_query:ForestDEV /server:AnyChildDC Name returns "Error_ACCESS_DENIED"
From the replication errors, it looks like the Forest DC's have not replicated to the Child DC's since April 2019.
I believe I can either try to run Reset-MachinePassword on DC05
Or Force Demote DC05
Doing this, I hope the Secure Channels from Forest DC's to Child DCs' will be rebuilt and replication will happen.
But, since the Forest and Child have not replicated in over a year, how are these partitions going to figure what data is valid? Even though this is a DEV Forest, from conversations, this is heavily used (Fortune 100 Company), so me breaking it would not be good.
Hi Experts,
Currently we are running Primary & secondary domain on win 2016 server and would like to add 2012 as 3rd DC and the reason being using is to utilize the Local administrator account management policies which not available in 2016 & 2019 but supports LAPS which is good solution but since the program shows in the add/remove program files I personally don't feel using it.
recently I installed 2008 R2 as 3rd DC and deployed the local admin account mgmt policy and it works fine considering this I linked to domain computers since then the policy not affect to even single workstation checked the rsop it applied but not affecting not sure what went wrong, so need to try with 2012 for this option.
Kindly advice if I can run both 2016 & 2012 dc's in the environment.
Thanks in advance
Hi everyone.
My internal CA certificate will expire soon (windows server 2008) and when I proceed to renewing process using the console the wizard end normally no error but when vewing the certificate Index number there is no new one and the same certificate remains the same.
Please help
Hi!
I have tricky problem. I have a Active directory setup where I have entered a password policy in the default domain policy. But when I run Get-ADDefaultDomainPasswordPolicy it shows different numbers than the ones entered in the default domain policy. It also seems to be those numbers that are in effect.
If I use Set-ADDefaultDomainPasswordPolicy and set a value that value will be populated into default domain policy as well.
What could be the cause of this.
Answers for a couple of questions:
- No finegrained pwd policy active
- The only policy that has password settings is the default domain policy
- There is no block inheritence for gpo:s on the domain controller OU
- Domain is 2019 at 2019 level.
Hi All
i would like to ask a question about Unsigned LDAP how one can explain it as simple as possible you know.
If you can't explain it simply, you don't understand it well enough.
So my assumption was that like with Certificates when Dc reply to LDAP query it signs LDAP with is private key, then client could check CRL having RootCA chain see that the replay is valid and authentic and decrypt with DC public key (SSL handshake)
i have a lots of Linux boxes they trigger Unsigned events (i know it could be false postive but still) my assumption was that if i install RootCa cert on them i would resolve the issue. but it seems that Kerberos itself its signed (with what ? krbtgt password?) also What does exactly Unsigned LDAP means? that client sending the query could not be check for autheticity ?? i could read MS documentation but no clear explanation is given imho.
so one thing that i am sure of is that i don't know how it is working =) thanks for any feedback
Hi,
We have 6 servers 2012 R2 and 1 server 2016 DC's in our domain. 2 of these are in the same subnet and the reset are in different subnets.
Today find out that when create a new gpo on the PDC this gpo dont get replicated to the sysvol of other DC's
I the gpo mangment console for this gpo can see that sysvol is inaccessible.
In the events of the PDC dont see any error regarding the replication.
Any suggestion on how to get the sysvol syned again?
Thanks
Shahin
UPDATE,
On the PDC see the DFS warning 2213. the last one is from 3 days ago.
Could this be the root cause of this issue?
Hi,
So I heard there is one-way and two-way ssl certificate for ldap. When you request for certificate do you need some special parameters for this or the oneway twoway function is more of how the ldap client and ldap server behaves?
For this example:
web application authenticating to AD via ldap, what certificate should this be? one-way or two-way?
I have looked into the documentation below but I can not find out if it will work with/ for IPv6, does the command listed below also work with IPv6?
New-ADReplication
Hi Everyone,
I have been tasked with trying to implement a GPO (if it exists), to prevent a user from logging in to multiple PC's at the same time using the same credentials.
From my research, thus far, there doesn't seem to be a solution for this. And i hope that is incorrect :P
I am using a Window domain environment, where the profiles are all local.
This is the long and short of what i am trying to accomplish. Hopefully, someone has a (Microsoft) solution.
Hello, in the TechNet site documentations about Active Directory, there is always a note stating that "In Windows 2000 Server and Windows Server 2003, the directory service is named Active Directory. In Windows Server 2008 and Windows Server 2008 R2, the directory service is named Active Directory Domain Services (AD DS). The rest of this topic refers to Active Directory, but the information is also applicable to Active Directory Domain Services. " or vice versa. Does this mean that AD and AD DS are the same but are named differently in different systems? If so, does the name AD DS also apply for Windows Server 2012, Windows Server 2012 R2 and further versions? It's not stating there. Although the documentations were updated in 2014.
On the other hand, in other documentations of Active Directory, e.g. Wikipedia, it seems to me that AD DS is one service that AD offers, which also includes other services such as AD LDS, AD CS, AD FS, etc.
Hello,
This is to request some guidance.
I do have a Default scope on my DC Server and it leasing ip address already.
I have created a new Subnet in my Network for users. Which i have created aScope on the Same DHCP Server, it's not leasing or giving out ip.
Please advise.
Thanks and Regards,
Ronald.

Hi,
I've got a 2003 domain with 2 DCs (2003 SP2) which needs to be migrated to another forest. The target forest has 2012 R2 DCs with a 2003 domain and forest functional levels. The forests have DNS and 2 way trust setup between them.
I'm after a step by step guide on how to migrate users, computers and required resources from the 2003 forest to the newer forest with 2012 DCs. Ideally, I'd like to do this with free tools such as ADMT.
Please can someone advise?
Thanks

Hello,
I have an issue with our AD, when I use the LDAP too, and I try to authenticate with the full UPN and and incorrect password, it will successfully authenticate.
Example 1
user@company.co.uk and incorrect password = authenticates successfully
Example 2
user and incorrect password = authentication fails
When you use the full UPN when using LDAP it seems to successfully authenticate. Any ideas why this is happening?
Hi All
one of my users active directory account is disabled. From the Attribute editor for that user, is there any attribute which tells me that this account is disabled.
