I created virtual desktops and those desktops got added to the OU. I right click on those desktops to go and manage it so I can add a user as the local administrator easily instead of going through each computer and adding it, and I GET THE following error. I am not able to open it.

Set "Subject Name Format" to "Fully Distinguished Name" for certificate template in Powershell.

Hello,

I have created a certificate template with all the properties I wanted. Except for one, which I cannot figure out.

Basically in the Subject Name tab it needs to select : "Build From This Active Directory Information" and then in the drop down for Subject Name Format it needs to say "Fully Distinguished Name"

Anyone knows the properties and values that need to be modified?

Any help greatly appreciated!

Domain trusts and logon servers

$

Hello,

I have a situation that seems a bit unique and all of the information I have found online doesn't quite match up to my scenario. 

I have two DC's server.domain1.local andserver.domain2.local when both domains are functioning normally by themselves, but I am trying to create a trust between the two. It would seem since they are both called server they cannot communicate even though they have different FQDN's. 

When trying to create the trust I get an error "There are no logon servers available" I get the same error when trying to UNC from one to the other.

I did create the conditional forwarders before creating the trust, and want to point out that they are connected via VPN and as far as I can tell from the traffic log the VPN Firewall isn't blocking any traffic. I also turned off thewindows firewall temporarily as a test to see if that was the issue.

Any help would be appreciated.

Thanks

Permissions for External Monitoring of Domain Controllers

$

We have eight domain controllers being hosted by an external data center. The data center administrators requested a domain administrator account for their monitoring tools and to apply monthly Windows Update patches.

Question: Is there a set of permissions I can assign their account which will allow their monitoring and update tools to work without the full domain administrator assignment?

Thanks for your thoughts.

Local account locking out domain account with the same name

$

We have a 2012R2 Standard Application server that has a local account configured that is used for the day to day operations of the locally installed application. We have a domain account with the same name but with a different password that is used for a service that performs file copies and print jobs to network locations.

We are seeing that the domain account is getting locked out even when the domain account is not in use or the service is not running. From the event logs on the DC (2016) we can see that the domain account is getting locked out from the 2012R2 application server but it would appear that the local account is querying and locking out the domain account?

I have seen other articles in which this is referenced, can you advise if this is expected behavior and why would the local account be attempting to authenticate against the domain?

AD 2019 New features

Hi All,

Is there any Microsoft official confirmation regarding AD 2019 features ?

Since we have found one for AD 2016 as below. But don't see any MS article for AD 2019. 

https://docs.microsoft.com/en-us/windows-server/identity/whats-new-active-directory-domain-services

From the below articles, we do see nothing new in AD 2019 except one performance update. 

https://adsecurity.org/?p=4187
https://www.reddit.com/r/sysadmin/comments/99etbt/whats_new_in_active_directory_2019_nothing/

But don't find any MS official confirmation regarding AD 2019 features. 

Group Managed Service Accounts - multiple domains

Hi, I want to know if GMSA created in parent domain can be used in child domain too or I have to create GMSA in child domain as well? GMSA is used as credential inAzure ATP Portal but we have 10 Domain Controllers in total (7 in parent domain/3 in child domain) in 2 domains - hence DCs in child domain should have right to retrieve password of GMSA in parent domain if feasible.

I assume answer is no but just want to confirm that. So far I have always used GMSA only on computers in domain it was originally created in?

Hello,

I have a forest with a domain that corresponds to my company.

This company is made up of several entities which have their own IT. I would like these computer scientists to be administrators of their OU.

That they can also be administrator of the domains of the servers of their OU, but only their OU and their children.

How to proceed?

Thanks a lot.


Active Directory Migration Issue

$
0
0

I am attempting my first active directory migration and having some problems Google can't help me resolve.

In order to utilize resources on the new domain ahead of the AD migration, the users have been manually created in the new AD. The idea of the migration is to:

  • Remove the old domain from use once complete turning a PDC into BDC
  • Migrate the users to new domain so they do not have to remember multiple account credentials
  • Maintain Security/Distribution groups
  • Computers will be moved manually so they can be "cleaned" and standard/approved software is available.
  • Users will be migrated with a merge, meaning any attributes that are set for newdomain\User will be maintained and not overwritten, only missing atrributes will be added again because we only created them to access specific resources on new domain)

I have two domains set up, users/groups/etc in both domains. I have created a trust and validated incoming and outgoing from each domain successfully. I made a test olddomain\User with Password123 and used ADMT to migrate the User to the new domain where newdomain\User with Password456 already existed. I then logged into a computer (still on old domain) with newdomain\username and Password456 successfully.

When I check AD it appears not one of the Security or Distribution groups were migrated along with the user. Some Googling led me to believe I should have migrated the groups first. I created a test Security group and placed this test User inot the group, then attempted to migrate the group and I'm met with"

    "Could not verify auditing and TcpipClientSupport on domains. Will not be able to migrate Sid's. Access is denied"

I tried adding the olddomain\domainadmin to my Built-In Admin group on the new domain but the error persists.

This is where I'm stuck, I'm not sure what the point of migrating these groups is if I can't migrate SID's. Has anyone seen and overcome this error?

Root CA vs Subordinate CA

$
0
0

Installing, what I thought, was my first CA and during the CA setup I am asked if this is the Root CA or Subordinate CA.  The weird thing is the wizard defaulted to Subordinate which confuses me.     That makes me think it detected something that result in it thinking I already have a CA somewhere in my environment.

We might have had a CA a long time ago but the CA feature is not installed on any servers in my environment.

How can I very this?

FGPP is applied, but still getting drop down notifications that password is expiring

Hey guys,

I am a domain admin and have a 2012R2 domain with Windows 10 clients(1909).  We have a default domain GPO the specifies maximum password is 90 days, but my account also booted up being member of an AD group that has a FineGrainedPasswordPolicy that is applied and says maximum password age is 10675199.  When I login to some web consoles, they are telling me that my account with expire in 12 days.  Does anyone have any ideas what I might be missing?

I saw this with Windows 7, but was assuming it is fixed with Windows 10

Dear all,

We have a fine grain password policy implemented in our domain and it is working as expected.

We have observed that password change reminder balloon message stays for few seconds less that 5 sec and most of the it is getting ignored by users and creating problem.

With FGPP - is it possible to increase time of reminder message and can we put our Custom message.

in-short we are looking setting for Interactive Logon Prompt which will display password change notification.

RODC DNS Server

$

Hello,

I have a DC a RODC (Both 2016). I configured my RODC DNS server to forward non AD queries (internet queries) to my ISP's DNS. My workstations have the RODC as primary dns server and the DC as secondary. The name resolution works fine but I realized that my domain controller also caches the requests of of my workstations. I checked that RODC have only my ISP's DNS in forwarders.

Now I wonder if DC and RODC synchronize the cache or my RODC do not actually forward the requests to my ISP but to the DC for some reason.

Thank you in advance.

2012 Active Directory Restore Plan Best Practice

$
0
0

I have one surviving vm DC in the environment that holds no fsmo roles. Its virtual. 

My primary dc contains all fsmo roles (all servers are 2012) and its dying.

1. My plan is to transfer the fsmo roles to the virtual dc.

2. demote old server.

3. Skip the process of restoring other VM DC from backup and just create new DC's and have them talk to the new virtual pc holding the fsmo roeles.

4. Clear metadata of the decommissioned dc using ntdsutil.

5.Remove reference of removed server from DNS.

6. Delete Old server from Sites and Services.

repeat steps 4-7 for all the other VM DC's that were replaced by newly spun up dc's.

This should avoid painful lessons and keep me in the clearly with no surprises in 90 days correct?

Or is there a painful piece of information I'm overlooking?


Domain Users accidentally added Administrators group in Active Directory and gets re-added because AdminSDholder

$
0
0
Because we wanted to apply a password policy to our domain we disabled block inheritance on the domain controllers OU.

But we did not know there was a gpo active on domainlevel that would added the local administrator and the domain users to the builtin administrators. Really bad design... but even badder we did not noticed. 
This gpo is no problem for the workstations but for the domain controllers it is!
This meant all the domain users suddenly were members of the administrators security group. Something you really don't want.
When we noticed we deleted the membership.

But because of the AdminSDholder the membership gets re-added after some time.
How can we prevent the re-adding of the membership to the Administrators group?

Kind regards,

Richard
