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

Hi,

When i'm doing a GP update from GP management i get an error on 1 server.
The error is 8007071a The remote procedure call was cancelled.

There a 3 servers in the same OU and only 1 server gives the error.
All servers are fresh install server 2019 standard edition, with the latest MS updates.

I have 2 server 2019 domain controllers in my lab.
Domain and forest level are at windows2016

Found some google hits talking about DFRS where i found an odd thing.
On both DC in \\hostanme\sysvol\contose.com\policies there are 4 files
But 1 file changed today. Date is equal, time is different.

I'm not familiar with replication so maybe someone can assist.


Thanks

Resource access via Sid History Vs Resource access via Group membership post Inter-forest Migration

$
0
0

Hello,

Resources are in the source domain. "Domain Local" groups of source domain are applied on resource ACL. Those source domain local groups had been migrated from source domain to target domain using Sid History and scope of the source domain group had been changed from domain local group (in source domain) to Global group (in target domain) meaning that now global group in target domain have Sid of source domain local group in Sid History attribute.

So If I add newly created user (created in target domain) inside migrated global group, his access token contains:

Sid for target domain user account
Sid for migrated global group of which the user is a member.
Sid for source domain local group in Sid History attribute of migrated global group

So newly created user now has Sid of source domain local group in his access token and that user will be able to access resource without source domain local group membership (either directly OR indirectly via nesting of migrated global group inside source domain local group).

Please confirm if this statement is true?

If the above statement is true, then what is the point of nesting migrated global group into source domain local group? In my AD infrastructure, I see that migrated global group is nested inside source domain local group.Why is this required? What is the main reason? Kindly explain.

I'm getting confused between "Resource access via Sid History Vs Resource access via Group membership" as the title says. So it would be great help if you share link of good articles for below mentioned topics that can clear all my doubts and confusion

1- Understanding Microsoft's Best Practice for group management

2- Resource access controls

3- Sid History

Please explain specific to all queries mentioned above. 

Thanks in advance!

Limit users who query AD ldap

$

Hi,

How do I prevent ordinary users from querying ldap? We have an application which we had one account used for application to connect to AD Ldap. What we have noticed is that ordinary users can do query against ldap. Can we apply delegation so that ordinary users cannot do query? If so, what would be the permissions? If ever we apply these permissions will it prevent them from logging in to the domain controller or use some other services?

Thanks,

Janus


RODC in DMZ - User Accounts can authenticate - Computer Accounts can not

$

Hi everyone,

i am having a RODC in a DMZ. Useraccount Authentication works fine (IIS and RDS Gateway) - but computer authentication does not.

Our RDS Gateway works with non domain joined computers. But when i try to connect from a domain joined - it fails.

Our Software Deployment Webserver can be accessed by browser with username and password but fails with the computer account.

Is the setup just not right for this purpose or did i miss something?

I removed the global catalog from the RODC because "some applications may not work right" but this did not fix it.

Anyone can help me out?

Best regards

Stephan

Group Policy Priority issue

$
0
0

Hi, 

We have a OU called NewPCs.

There is a GP linked to NewPCs that disables Remote Desktop connections and it is marked as enforced.

Under NewPCs there is another OU called ABVM

There is a GP linked to ABVM that Enables Remote Desktop connections and it is marked as enforced.

I expect that the GP applied to the more specific OU would have the highest priority and that remote desktop would be enabled for computers in the ABVM OU.

However,, remote desktop is being disabled by GP.

Does anyone know what is going on with this?

This exact same heiarchy works flawlessly in other OUs, so I have no idea why it isn't working here.

Excessive 4624 and 4634 events

$

Windows Server 2012 AD DC, users on Windows 7 SP1 x64 are logging in (~800 or so users). A small percentage of them are generating 300-400 logon events in the Security log - *per second*. 

Most other users are not generating excessive logon events... this is filling our security log quite fast. 

P.S. I suspect this happened after Logon and Logoff event auditing has been configured in the Advanced Audit Policy Configuration (Success and Failure). Still - most users do not generate that much logon events when logging in. 

Some incompetent moderator is marking all similar questions as answered even though they are NOT. So I am reposting - yet again - and let's hope this time the mods will hold their horses until the reason and a solution is actually found.

Group Managed Service Accounts: -PrincipalsAllowedToRetrieveManagedPassword

$

Hi

So the documentation (https://technet.microsoft.com/en-us/library/jj128431.aspx) for creating gMSAs says that the parameter "-PrincipalsAllowedToRetrieveManagedPassword" should restrict the ability of using the gMSA to the machines that are part of the security groups given in the parameter. E.g.

New-ADServiceAccount -name dev-service -DNSHostName dev-service -PrincipalsAllowedToRetrieveManagedPassword gMSA-dev-service-allowed-hosts

should, as I understand it,  allow only the machines that are part of the security group "gMSA-dev-service-allowed-hosts" to access the password of the the account dev-service thereby limiting the machines that can use the account.

My problem is that I can not get it to work that way. Even on a machine that is not a member of "gMSA-dev-service-allowed-hosts", the account can be used without problem.

Did I misunderstand the meaning of -PrincipalsAllowedToRetrieveManagedPassword ?

Thanks

Best,

Deniz

Adding WS2016 to existing domain

$

Hello,

I know this is a simple one, but for some reason I am struggling. I have two WS2016 machines, one is domain joined and the authoritative DC. The other is not domain joined and I have been trying to add it to the domain via Server Manager. I have already set the DNS settings to target the original DC, so DNS settings are fine. I have also disabled the Windows Firewall to prevent any interruptions from it. The specific error I get when trying to join is "The wizard can not access the list of domains in the forest. The network path was not found." For reference I will put the internal IP addresses below to help.

Original DC: 192.168.1.217

Machine I'm trying to add to existing domain: 192.168.1.227

Thanks,

Connor

dns and ad not working.

i get this error in dns log

The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

I get this error in ad

The security of this directory server can be significantly enhanced by configuring the server to enforce  validation of Channel Binding Tokens received in LDAP bind requests sent over LDAPS connections. Even if  no clients are issuing LDAP bind requests over LDAPS, configuring the server to validate Channel Binding  Tokens will improve the security of this server.
 
For more details and information on how to make this configuration change to the server, please see https://go.microsoft.com/fwlink/?linkid=2102405.

Grant User Read Access to DNS Server

$

Hi,

I would like to allow a single user read access only to our DNS server.

On the Security tab of the DNS Server properties, I have added the user with Read only rights.

This does indeed allow him to connect to the DNS server, but what I have found is that he can actually make changes to the Forward Lookup Zones i.e. he can add new host A records and also delete existing records.

When I look at the Effective Access for the user, it comes back to tell me he has nothing but Read access (which is what I would expect), but he can indeed make changes.

Am I missing something here?

Thanks,

Bob

Is there any known issue in AD 2016 ? We see there there was an issue when a non-Windows platform application which performs LDAPS queries against AD 2016 as per below blog

https://blogs.uw.edu/barkills/2017/09/11/ws2016-ad-upgrade-problem-tls-ciphers/

Not sure whether it is still an issue. Additionlaly we see that SMB 2+ over NetBT is deprecated for AD 2016 as per MS, is there any potential issue can occur because of this ?

Servers are not getting authenticated with their Gateway servers through Kerberos.

Hi ,

We recently faced a issue where some of the servers are not getting authenticated with their Gateway servers through Kerberos. So we received few alerts for heartbeat failure. When we check the status of the server, they were pingable and able to RDP. 

we tried restarting the Microsoft Monitoring Agent service(MMA) but still the alert is not getting cleared from SCOM.

Here the environment is Parent and Child. for example: AAA.local is the Parent domain and bbbb.AAA.local is the child domain.

Servers in child domain have alerted as unable to authenticate Gateway server in Parent domain through kerberos 

We are asked by the client to check Kerberos authentication between Parent and Child in the domain.

Following troubleshooting steps we performed:

1>We checked the Trust between Parent and Child domain, its getting validated. No errors.

2> We checked the PDC emulator of child domain, its showing no errors.

3>We checked few servers which alerted and no event found for the same at the time when alert got generated.

Looking for some advice/suggestion in this case. Please assist.

Sidhistory vs Recursive group membership vs access token

$

0
Hello,

I migrated users and groups from source to target domain using sidhistory of both users and groups. So when user login to target domain and access token is build, 

Please confirm if it contains:

Sid for target domain user account
Sid for target domain groups of which the user is a direct member.
Sidhistory for target domain user account (Sid of source domain user account)
Sidhistory for target domain groups (Sid of source domain groups) of which the user is a direct member

Now my questions are

1- Does access token also contains Sid for all recursive target domain groups of which user is an indirect member?
2- Does access token also contains Sidhistory for all recursive target domain groups (Sid of source domain groups) of which the user is an indirect member?

What I mean by recursive group membership is: for example User(source/target) is member of Group1, Group1 is member of Group2, Group2 is member of Group3 and so on

Kindly reply specific to all points mentioned above.
