Hi all,
We have 2008 R2 AD controller, we installed 2019 server as a AD controller and we upgrade the schema.
Most of application using LDAP request stop working.
example of error :
javax.naming.PartialResultException: Unprocessed Continuation Reference...
i see that, we must change port 389 to 3268 GC...
My question : How we must do to continue to use 389 port without changing any thing in the application, and accept referral mode in LDAP?
why that work good before and not work fine now?

Few days ago . Our Primary Domain Controller named "PrimDC01.pooja.com" becomes hangs . Upon forcefully shutdown and then start , it stopped functioning properly .While check , we observed that FSMO roles were transferred to additional DC named "ADC01.pooja.com".After that we can add/remove users successfully in AD . Join workstations to AD successfully , however while joining any new Win Server 2008 R2 , its not joining to AD. DNS is not updating/adding records of newly joined workstations .
Exchange Server DAG is not connecting. Cluster Nodes are not communicating with each other. Throwing error of 'authentication problem'.
Emails flow stopped. No email send /receive .
We run AD health check and got this result .

Can anyone tell me what are the best practices to be followed while configuring Group Policies in a domain.
I would like to know in particular what all User and Computer policies need to be configured following best practices, in which level in the AD the group policies should be configured ideally, etc etc.

Hi,
We are trying to integrate with another AD environment. We need to access Data from this new Domain.
We are creating the One way Trust. So do we need a RODC setup in new domain?

Hello All,
I am trying to add a 2019 server to our existing domain and it gives me this error:
verification of replica failed. the forest functional level is not supported. To install a Windows Server 2019 domain or domain controller, the forest functional level must be Windows Server 2008 or higher.
We are currently functional level is 2008 R2.
Restarted the new server to no avail. According to everything I have researched this should work.
Any insight would be a great help
Thank you :)
Hi,
I am getting the below error when entering GPupdate in server 2012. How to address the below issue.
provide me the step by step troubleshooting.
Computer policy could not be updated successfully. The following errors were encHello. Have an issue where our primary domain owner server starting booting to a blue screen. Code is 0xc00002e2.
If we select DSR mode, it will boot to safe mode but dcdiag shows all kinds of problems. Not exactly sure the next best steps. Do I try and fix the problem which I am having trouble figuring out exactly what that is? Should we do a "role" seizure? ... Which I have never done and a little nervous what might happen. Is there a rebuild routing that might find/fix issues with AD?
Any assistance would be greatly appreciated...
thx !
Hello Microsoft TechNet,
Please can you help with the query below.
We have introduced two new Windows 2016 Domain Controllers to a Windows 2008 R2 Active Directory.
We are seeing the error below in Event Viewer
Error ID 4015
The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly.
The Forest and Domain functional levels have been left at 2008 R2 as there are still other Windows 2008 R2 Domain Controllers in existence in the Active Directory.
Please can you help troubleshoot this error.
Many Thanks in Advance.
Dan,

hello all,
have an issue and i would like some assistance.
i Have 3 domain controllers and i successfully migrated the SYSVOL replication from File Replication Service (FRS) to Distributed File System (DFS Replication) one week ago.
then when i was trying something else my DHCP broke at the PDC so i had to restore to a backup and the latest backup which i had was prior the nigratoin of SYSVOL. so now i get error messages.
PDC: when i run the command: dfsrmig /getmigrationstate i get the the PDC is in (eliminating) state
when i run the same command from the other two domain controllers i get: "Unable to connect to the PDC emulator. Make sure that the PDC is reachable and retry the command later."
any help would be appreciated.
Ok, this is a weird one.
I cannot access file shares in a 2 way forest trust on 1 site only but works if the firewall is down! Monitoring log shows no dropped packets.
Domain admin\enterprise admin\administrators exist in built\admin group on each side.
Trust is validated from both sides.
All servers ping in all directions.
Domain B, access file share site 1 \ does not work. Drop the firewall - works.
Domain B, access file share site 2,3,4,5 \ works fine. Firewall is up.
RRAS sits between them, none domain joined. Has NIC in both Dom A and B. Static routes configured for Domain A gateway for all Domain A sites. Nothing else.
What am i missing?
Firewall rules are controlled via GPO across all sites so all servers are the same.
Totally baffled.
We moved the main (and only) DC from one host to another and in the morning users could authenticate to the DC, they could ping the hostname, domain, ip address, I did the basic troubleshooting like flush dns etc but it didn't work
Users were not able to remote into the terminal server as it couldn't authenticate with the DC and if you created a new share you could give permissions to anyone on the domain only a local account.
I have 2 RODC domain controllers configured in a site but I see no computer or users are authenticating against the RODC's.
I checked the Allowed RODC password replication Group and it has all the PC's in that site and a handful of user accounts. I even checked the Accounts whose passwords are stored on this Read-only Domain controller and it shows me all the computer objects and the user objects.
However, when I login to any machine in that site it authenticates against the RW DC from another site.
I checked echo %logonserver% and Set L and each time it shows me a RW DC and not the RODC.
Can anyone tell me why the users or client machines are not authenticating with the RODC?
Thanks

Dear All,
I need to migrate Active directory from 2008r2 standard to 2012r2 standard in Hyper-v of 2012r2 standard server.
I have created two virtual Machines in hyper-v and one new private virtual switch and connect both virtual Machines to that switch.
VM1-2008R2-IP: 192.168.2.2
VM2-2012R2-IP: 192.168.2.1
dns: 192.168.2.2
Both machines are pinging to each other.and they are on the same network.
previously 2008r2 domain server was on diifferent network and its ip was 192.168.1.206. it was migrated from 2003 server
2008r2 is still working on dedicated physical machine on the subnet of 192.168.1..... . I created the VHDX file of server and run on hyper-v.
I have also created new zone of 192.168.2... network and also created new pointer to 192.168.2.2 in reverse lookup zones.
when i tried to join 2012r2 server which is installed in physical machine to existing domain on network of 192.168.1..... . it joined but on hyper-v with different network it shows error: can not complete this funtion.
Please help and suggest me. What should i do to reslove this error.
can any one help me on this.
Hi,
there is something strange happening with our company's domain environment, especially with DNS servers. Our domain controllers do not have ad-integrated DNS server, they are using InfoBlox DNS appliance instead. When I nslookup the IP address of one of domain controllers, the result is:
> 192.168.10.3
Server: DomCtrlr1.domain.lan
Address: 192.168.10.3
Name: domain.lan
Address: 192.168.10.3
> 192.168.10.3
Server: DomCtrlr1.domain.lan
Address: 192.168.10.3
Name: DomCtrlr1.domain.lan
Address: 192.168.10.3
> 192.168.10.3
Server: DomCtrlr1.domain.lan
Address: 192.168.10.3
Name: domain.lan
Address: 192.168.10.3
> 192.168.10.3
Server: DomCtrlr1.domain.lan
Address: 192.168.10.3
Name: DomCtrlr1.domain.lan
Address: 192.168.10.3
> 192.168.10.3
Server: DomCtrlr1.domain.lan
Address: 192.168.10.3
Name: domain.lan
Address: 192.168.10.3
> 192.168.10.3
Server: DomCtrlr1.domain.lan
Address: 192.168.10.3
Name: DomCtrlr1.domain.lan
Address: 192.168.10.3
> 192.168.10.3
Server: DomCtrlr1.domain.lan
Address: 192.168.10.3
every odd DNS query returns only the domain name, every even query returns the FQDN name of the domain controller.
Does anybody know what is not configured properly or what is not OK?
Hi,
We want prevent domain administrators to connect on workstation due to security reason.
how we can prevent domain administrators to access on workstation?
Hi all,
I've demoted several 2003 Servers during the last few months in our customer AD, moved subnets and succesfully deleted sites under ADSS.
So far, so good, but in DNS I can still see entries under _sites and nameserver domain properties tab.
As per the nameserver domain tab, I think they can be deleted as they are unreacheable/unresolvable records, I still got confused though by the _sites entries as some of them are not showing up and some others are still there and they has an entry under _tcp that point at a DC that has never belonged to the sites in object, but has some FSMO rules.
Some interesting points:
I'm somewhat new to advanced DNS management, How I can safely go further from here?
Thanks
I am having issues with Macs connecting to the domain and I just want to understand what the error message means.
The following client performed a SASL (Negotiate/Kerberos/NTLM/Digest) LDAP bind without requesting signing (integrity verification), or performed a simple bind over a clear text (non-SSL/TLS-encrypted) LDAP connection. Client IP address: 10.63.10.23:55885 Identity the client attempted to authenticate as: Domain\test-mac$ Binding Type: 0
Plus, I am seeing some services connect with Binding Type: 1
When I force the mac to use signing, it just doesn't connect. dsconfigad -packetencrypt ssl or dsconfigad -packetsign require
Is this an actual issue that I need to be worried about or what?
Thank you
Charles
