Hi,
I have a Primary Domain Controller and Secondary Domain controller. The problem is that when Primary Domain Controllers goes down, Secondary Domain Controller does not authenticate the users.
I've an Exchange Server in the environment but everything goes down with Primary Domain Controller.
Any thoughts?
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...
Hi All,
I have 3 Domain controller under ABC.COM. All the five roles in DC1, DC2,DC3 additional domain controller.
My requirement and query is when the DC1 is down due some failure. All FSMO roles need to move automatically to another DC. Either DC2 or DC3, If it possible ?.I have seen some articles in Microsoft that option is possible.

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

Can i use one of my on-premise systems?
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.
Dears,

Hello,
I recently upgraded to Windows 10 from 7 and found I can no longer access files I encrypted. I don't remember setting a password when I encrypted them, did it default to my Windows user password? I'm not even sure I had one at the time I encrypted the files!
Not sure what to do next.

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.
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 helpHello Team ,
We have DC server and ADC server domain and forest functional level 2000 Native . DC and ADC sync successfully if our DC Down ( which is hold all FSMO role) user not able to access file folder and network resource . when our DC again online user to able to access the file folder and network resource.
Hi Team,
We are in the process of AD domain consolidation\restructuring, I want to know from first to last what are the things that I need to consider, any response would be of great help
Thanks in advance.
Regards.
TIA,

I have configured a Windows 2016 system with an AD LDS role, SSL enabled it and am trying to do some additional verifcation of the environment. I have a defined account within the directory that is enabled and has a password assigned. I had expected to use LDP to remotely confirm the authentication of the system from my workstation as I had already confirmed that I could attach to the directory locally from the server with the appropriate host name, ssl enabled and port defined.
My connection via LDP from the local server (while authenticated as an admin account) returns this:
ld = ldap_sslinit("MYINTERNAL.SERVER.NAME.HERE", 636, 1);
Error 0 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3);
Error 0 = ldap_connect(hLdap, NULL);
Error 0 = ldap_get_option(hLdap,LDAP_OPT_SSL,(void*)&lv);
Host supports SSL, SSL cipher strength = 256 bits
I am able to subsequently bind using the directory account without any apparent issues.
My remote connection from my workstation via LDP (from an entirely different AD domain and account) returns, while using the same connection paramters, this:
ld = ldap_sslinit("MYINTERNAL.SERVER.NAME.HERE", 636, 1);
Error 0 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3);
Error 81 = ldap_connect(hLdap, NULL);
Server error: <empty>
Error <0x51>: Fail to connect to tswadslds03.qa.int.dmz.hban.us.
and concludes with a pop up window stating: Cannot open connection
When I do a bind from the local client using the directory account AFTER attempting this connection it would appear that the account had authenticated but while using port 389 as reflected below:
ld = ldap_open("MYINTERNAL.SERVER.NAME.HERE", 389);
Established connection to MYINTERNAL.SERVER.NAME.HERE.
Retrieving base DSA information...
Getting 1 entries:
Dn: (RootDSE)
I am guessing that LDP in this instance is not getting connected successfully via SSL as originally attempted BUT do not understand exactly why it worked locally via SSL. When I attempt the connection via SSL using the IP address, I get an Schannell error specifying that the certificate did not match the name but no error at all when using the FQDN from the local client.
Any insights / suggestions / references on this would be appreciated.

We replicate a number of vital PROD servers to our DR site and are having a major issue. In the DR site, there is a domain controller (not the PDC) which syncs with the domain controllers in the PROD site so it is always up-to-date.
I our tests we failed over our PROD servers to the DR site and found that the domain controller in the DR site, when rebooted, takes around 90 minutes to boot up and gets stuck at the "Applying Group Policy" screen.
Looking at the logs, I can see EVENTID 3096, "The primary domain controller for this domain could not be located" and I feel that this is the reason the DR domain controller is taking so long to boot.
Is there a fix for this - where we can stop the DR domain controller from looking for the PDC??
The DR domain controller is Windows 2008 R2. Thanks.
EDIT:
I just found out that the domain controller is set to DHCP for an IP and it does not look like it found a DHCP server!.
