Dear all,

I have the following topology:

Two domain controllers (windows server 2008 r2 ) and one cas/hub server and one mailbox server

We have to shut down the primary domain controllers for physical maintenance but before doing this I transferred the masters roles to the additional one ,then shutdown the domain controller but due to a failure in the hard disk of the domain controller I made a bare metal  recovery then  made a dcdiag and I found the following errors

please advuce

objects linked to a computer SID

$

Gents,

I'm trying to find a way to have a comprehensive list of objects related to a AD computer (or possibly its SID) in order that, before deleting that Computer Account, there will be no orphaned object with link to this Computer

For example, let's say i have a GPO with a security based filter pointing to a computer (the question here is not about whether or not is it a best practice). If i deleted the computer, i will be left with the SID when i look at this GPO

The same applies for a Security Group which this computer could be a member of. If i delete the computer account, the security group will have an SID instead

To prevent this, i would like to have command lines or a script which would search amongst all AD objects and find which one has a relationship with the computer account (or its SID) so that i can make some cleaning BEFORE deleting the computer account

Does that make sense to you ? Anyone has already found something to reach that goal ?

Thanks very much for your feedback

Add a manages tab to Active Directory

$

Hello there

So for a while now we have been using the "managed by" tab in Active Directory to keep track of who owns what computer.

Now the problem is that if we know which pc we want to find the user for its easy, but the other way around(User->pc) we have been using powershell to find, this is a bit of a hurdle and would be nice to just integrate in AD. So my question is: is there a way to add a tab on a user that has a list of pc's owned by that user (some have multiple pc's). In the same way the "member of" tab works.

Thanks in advance

UDP port range for AD

I am looking to open port between 2 server that are behind firewall. I got the following link from the Microsoft site.

http://technet.microsoft.com/en-us/library/dd772723(v=ws.10).aspx

However, if you check one of the section says

UDP Dynamic

Group Policy

DCOM, RPC, EPM


Any idea what could be these port range

Only one referral for SYSVOL and NETLOGON

$
0
0

I have a problem that is sort of opposite of what most people experience.

We have network with two AD sites, and a lot of subnets but all the subnets are assigned properly. we have 3 DCs in Site1 and 2 DCs in Site2. All DCs are Server 2016, Forrest and Domain Functional levels are also 2016.

Authentication works as expected, users are authenticated against the closest DC. 

Replication is DFS-r and it works as expected. GPOs, scripts etc. are replicated within site(s) and between sites fast. 

Problem is this:

when I login to client in Site1 and run dfsutil /pktinfo to check referrals for \\domain.name\SYSVOL  i see only one DC from Site1 even though that site has 3 DCs and I see no referrals from Site2.

if i login to client in Site2 and run dfsutil /pkinfo i see only one referral for SYSVOL, which is DC from Site2, and no referral from Site1. Referrals are random and always from matching site.

we also use DFSn a lot and those referrals are as expected. when i check properties of the folder there are always names from the home site and two from the remote site no matter where i am looking at the shares. Only SYSVOL and NETLOGON show that behavior where clients get one and only one referral.

Another issue, which is probably related, if i am logged into Site1 and try \\DCfromSite2\SYSVOL i get "access denied" and vice-versa, if i am logged in in Site2 and try \\DCFromSite1\SYSVOL i get "Access denied". But i can access them vie \\...\C$\windows\SYSVOL so it is not permission issues.  

i've spent days browsing internet but couldn't figure out solution.  

 Any help is greatly appreciated.

Hi,

I am having two different forest running in our infra. Forest A and Forest B. One of the application is part of Forest A. The users available under forest B wants to access the application with their domain credentials. We do not want to create any trust between them because the requirement is to access LDAP only.

How do i create a LDAP referrals between those forest to access LDAP?

Any help is highly appreciate.


The security of this directory server can be significantly enhanced

hi all,

today tI found that replication was not occuring because of one of the objects can not be updates 

as follow

  

ctive Directory Domain Services could not update the following object with changes received from the following source directory service. This is because an error occurred during the application of the changes to Active Directory Domain Services on the directory service. 

Object:
CN=M M,OU=Users,OU=HD,OU=Technical Support,OU=Users,DC=mydoamin,DC=local

Synchronization of the directory service with the source directory service is blocked until this update problem is corrected. 

This operation will be tried again at the next scheduled replication.

so I fix this solution making a defragment of the ntds database .but after that i run dcdiag and found 

this warning in KCC what should I do about it 

        Event String:
            The security of this directory server can be significantly enhanced
by configuring the server to reject SASL (Negotiate,  Kerberos, NTLM, or Digest)
 LDAP binds that do not request signing (integrity verification) and LDAP simple
 binds that  are performed on a cleartext (non-SSL/TLS-encrypted) connection.  E
ven if no clients are using such binds, configuring the server to reject them wi
ll improve the security of this server.

I work for a fairly large organisation with multiple remote offices. I am trying to find out if there are users setting up their own small shadow domains not connected to Corp domains. How could I go about identifying these domains? and what tools do i need to use to identify them either through LDAP/ DNS queries etc.

Active Directory FSMO Roles Question

$

Hello,

Our company has 4 Domain Controllers, 2 in each Datacenter. They've failed over to the secondary cutting off the 2 DC's in the primary site, one of which had all the FSMO Roles. 

So my question is,

With this excercise lasting for a few days, should we have the DC's in the second site seize the FSMO Roles?

And if seized, when the primary comes online will it automatically be moved back to the original Primary server? 

Thanks

WIndows 2012 R2 Active directory promblem after applying GPO

$

Geetings,

We have a single domain  based on two DCs  windows 2012 R2.
We added  a gpo on  domain tree in GPMC. I noticed  that  access to domain exchnage store  stooped and immediately removed the GPO. But it was too late. It seems that has done some issues to Active directory.

All domain computers and member servers have lost  introduction with the DCs. What I mean is  that , instead of the domain name ,on network icon, appears "network".
I removed  and rejoined  computers  on the domain  without problem but still the domain name is not come up. ONLY the two DCs  have domain name on network identification.


All domain services (DNS,netlogon) are running.
My main concern is the exchange which  I removed and rejoined  on domain but  network  icon says "Network" Not the domain name  ( Information store and  exchamnge address is in "starting" mode)

I did  dcdiag /c  for DNS testing  and failed   on  Delegation test
The error reffered to an oold  dc that has been  removed  a year ago. Is that could be a problem for the whole domain systems to see: the domain ?I beleive ius the GPO taht caused the issue. But I am lost on what that might be

Thank  you for listening. Any ideas will be more appreciated.

DNSLOOKUP AD Domain

when I use NSLOOKUP for a AD Domain (example:Domain1,example.com). I noticed some IP addresses listed are DCs that were decommissioned. any idea where these IPs come from, I checked the zone and I don't see these IPs listed.

Example:

Nslookup

Domain1,example.com

Some IP listed are DCs that were decommissioned.

If I lookup the SRV for the zone:

Set type=all

_ldap._tcp.dc._msdcs.Domain1,example.com

the correct DCs list returned.

Thanks,

Hi,

So this is our setup. We have 10 AD/DNS, 2 of which have their DNS Forwarders pointing to the other department's DNS server facing the internet. Now our security team called our attention because of DNS traffic from the two AD/DNS servers to public IPs, there are about 700 IPs that they want us to check. Now I have checked some of  these IPs and they are legit coming from cloudflare, amazon, Microsoft, etc... My question is How do I respond to them and affirm the validity of these DNS traffic and I want also to know how the workflow of DNS query is.

Enabling AD DS Recycle Bin fails

Trying to enable the AD DS Recycle bin, and it is failing with an error message (at end of post)


Going through the check list for enabling this feature, as well as numerous other posts from technet / Microsoft.

Forest Functional Level - ((get-adforest)) ForestMode:Windows2008R2Forest .  Verified.

Credentials: My user is an Enterprise / Schema admin. I added it to Domain Admins specifically when this command failed as a test.

Running PowerShell as an Administrator (Elevated Privileges) :: or without, and it is the same result.

To double check the module load, import-module activedirectory has been run.

Enable-ADOptionalFeature -Identity 'Recycle Bin Feature' -Scope ForestOrConfigurationSet -Target xyz.priv   ((where xyz.priv is my actual domain)) there are no sub-domains.  Also, entering the Distinguished name for the recycle bin feature has the same results.

Also - If I run just Enable-ADOptionalFeature  it prompts me for -Identity, -Scope, -Target, and when supplied comes back with the same error.

 

I've tried this short hand, or with the full DN going as far as copying it from the atrribute set from Sites and Services.  I even verified effective security permissions on the Recycle Bin Feature msDS object, and the configuration partition lists the object 'CN=xyz'  crossRef properly when looking at it through ADSI edit.

 

Do I really have a typo somewhere, or process error?
