Hi,
I have three windows server 2012 r2 domain controller on three different subnets and window 8.1 , windows 7 clients.
Frequently users domain lock automatically or thier sessions with domain controller losses automatically (RANDOM) due to which when they open internet explorer for internet (PROXY SERVER - TMG) they asked to provide authentication. i checked event viewer and found following logs.
Event ID : 4776
The computer attempted to validate the credentials for an account.
Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
Logon Account: abcd.zyx
Source Workstation: FNC-AHSAN
Error Code: 0xC0000071
Event ID : 4771
Kerberos pre-authentication failed.
Account Information:
Security ID: CSAPLHO\hasnain.abbas
Account Name: hasnain.abbas
Service Information:
Service Name: krbtgt/CSAPLHO.PK
Network Information:
Client Address: ::ffff:10.1.0.47
Client Port: 2751
Additional Information:
Ticket Options: 0x40810010
Failure Code: 0x12
Pre-Authentication Type: 2
Certificate Information:
Certificate Issuer Name:
Certificate Serial Number:
Certificate Thumbprint:
Certificate information is only provided if a certificate was used for pre-authentication.
Pre-authentication types, ticket options and failure codes are defined in RFC 4120.
If the ticket was malformed or damaged during transit and could not be decrypted, then many fields in this event might not be present.
I restarted all domain controllers but still not able to find any solution , pls help and advise.
Hi
Whilst trying to understand functionality of "BUILTIN\Pre-Windows 2000 Compatible Access group" and i was able to enumerate a specific set of Information ANONYMOUSLY when using certain APIs like SAMR named pipe with SMB, detailed HERE. The tool i used to enumerate Information anonymously from AD using a a NULL session is called SuperScan.
The Key in this First Scenario is add to special identity"NT AUTHORITY\ANONYMOUS LOGON" to "BUILTIN\Pre-Windows 2000 Compatible Access group" and use a software which uses noted APIs to query/enumerate information.
If we look at Default Security Descriptor of Domain, we can Pre-Windows 2000 group is present with some pre-defined level of granted rights (Refer first image pasted below).
Now i continue with the Second Scenario where i try to enumerate information anonymously but using LDAP/LDP.exe
Now by default with Windows Server 2003, anonymous LDAP Bind operation isn't permitted, unless this behavior is explicitly has been overridden usingDsHeuristics attribute. As per this article, author indeed changed the noted attribute value but he also changed the Security Descriptor of targetted Containers (in author's case - SENECA) to allow "NT AUTHORITY\Anonymous Logon" with List Contents and Read permission!
Now if we don't add & grant rights to "NT AUTHORITY\Anonymous Logon" for the given container/object, then we won't be able to Search/Browse information anonymously using LDP.exeand this is the part that confuses me.
If i look at the default ACL of Domain Object, we see that by default, multiple permissions including LIST contents & READ permission exist for "BUILTIN\Pre-Windows 2000 Compatible Access group" applied recursively (This Object and all child Objects), as shown in attachment.
Now If i have already added "NT AUTHORITY\ANONYMOUS LOGON" to "BUILTIN\Pre-Windows 2000 Compatible Access group", then "NT AUTHORITY\Anonymous Logon" should automatically possess all of the rights adhered by "BUILTIN\Pre-Windows 2000 Compatible Access group" and i should be able to view information anonymously using Simple LDAP bind, but indeed its NOT! Please correct me if i am wrong here.
I am trying to enumerate information under USERS container anonymously.
Please Assist.

Hi
KB216970briefs about the role of Global catalog for Accounts (User and Computer) in various operations like explicit UPN name resolution, Group membership population in case of Domains with Functional level >= Windows 2000 Native (i.e. with introduction of Universal Security groups).
At the bottom of this KB, it states
"In a Mixed-mode domain, universal groups cannot be created. If a Windows 2000-based computer is located in a down-level or Mixed-mode domain, different behavior occurs. Other domains may be in Native mode and universal groups may have been created that contain the user as a member. The domain controller authenticating the logon request will add the SIDs of the global groups of which the user is a member to the user's token and the local computer adds SIDs for groups of which the user is a member on the local computer as appropriate. When an attempt to use resources in another domain occurs, the computer hosting the resource contacts a domain controller for that domain, which adds the SIDs of the groups local to that domain (which may include universal groups) of which the user is a member to the user's token."
The highlighted part confused me and indeed it doesn't work so as stated. Hence, I tried to simulate this scenario, please have a look at THIS Document covering this case scenario and please let me know if i am wrong in deducing the quoted text or implementing the simulation as per quoted text!
Please Assist.
Thanks

Hi guys,
This is the exact log we receive up to 5 times in an hour in Event logs:
EventID: 0x00000004 (4) >The Kerberos client received a KRB_AP_ERR_MODIFIED error from the serverserveros1$. The target name used was ldap/serverok1. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal
name (SPN) is registered on an account other than the account the target service is using. Please ensure that the target SPN is registered on, and only registered on, the account used by the server. This error can also happen when the target service is using
a different password for the target service account than what the Kerberos Key Distribution Center (KDC) has for the target service account. Please ensure that the service on the server and the KDC are both updated to use the current password. If the server
name is not fully qualified, and the target domain (KOCOTO.LOCAL) is different from the client domain (KOCOTO.LOCAL), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server.
I checked if there are duplicate SPNs or DNS records but didn't spot any. There are no non-existent or unused account in ADUC. The servers questioned are both DCs running Server 2008 R2 on them. We receive this log only forserveros1. I think it's been like this since the day we installed the system.
It doesn't seem to cause any specific problems or it's just that we didn't face it yet.
I'm looking forward to listening your thoughts and advices on this.
Thanks in advance.
Hi
If I have a Windows 2003 domain controller server and I want to move it to a new Windows 2012 server, why do I have to upgrade the 2003 server before I can move it over?
The question was in a practice test but I don't get why you would have to do this?
Thanks
Aaron
Hi ALL,
Anyone could help me in finding reporting tools for Active directory
Thanks
I have a account which is keep locking out but this happens night time where we are not able to take logs or grab logs. So what I like to do is write a powershell script to take these logs for me.
I'm using AL TOOLs. Within ALTools the is program called LockoutStatus with this program they is column calledOrig Lock
I just like to know where this information is collected from, is it from even or from user?
I only need the Orig Lock info
Please see below screenshot
So I have a small domain, 1 forest, 1 domain - maybe 10 users / computers. I am looking to replace their DC (Windows 2003) with a new server, (Windows 2008 R2).
So I got my new server all fired up and patched. I joined it to my existing domain. Then the AD DS role was installed on the new server.
Then, I raised the forest and domain functional level from Windows 2000 native to Windows 2003. Then, on the 2003 DC, I ran adprep /forestprep, adprep /rodcprep, and adprep /domainprep /gpprep.
Once this completed, I tried to run dcpromo on the 2008R2 dc and it will not complete. I am selecting adding it to an existing domain in an existing forest, but it keeps telling me that I need to run adprep /forestprep in order to continue. I am a bit stuck - I haven't gone through the process of 2003-2008 in a few years now so I feel like I am missing something.
Any help is appreciated.
Thanks

Hello,
We have a domain (abc.com) running two windows 2003 domain controllers. User names are in Arabic language. Now we are planning to create a windows 2012 r2 active directory domain (abc.local) in our environment and to migrate all the users from windows 2003 domain to windows 2012 r2 domain. There is no connectivity in between two domains old and new (abc.com and abc.local). total number of users are 150.
Please advise and guide what is the best possible way to achieve this goal.
Thanks in advance.
Hi,
I have an active directory with two dns (windows server 2012 datacenter) and I would like to know how I can deploy the print management console in AD (per computer)?
What I really want is to manage and drivers and printer in the computers of the domain. Now I'm able to deploy printers.
Thanks in advance.

Hi,
I try to rename a domain but it is not possible to change the case of the TLD from LOCAL to local for the LDAP Attribute DC (possible it will also not work for the domain part, but this I didn't try).
Any idea where the case is saved? I think it must be stored somewhere in ldap, but I dont know whre (ldap search for *=local do not perform).
I also tryd the rename from domain.LOCAL to domain.test (where the case was ok) and back to domain.local, but it become again domain.LOCAL.
Notice: the dns name is renamed the the right case (only on some points you can read the tld with upper case), but not the ldap attribute (I see DC=domain,DC=LOCAL)
Regards,
Thomas
Where I work we must join computers to the domain using the netbios name (ex: mycomp) vs the FQDN mycompany.tx.com or else problems occur and the computer must be rejoined to the domain again with the netbios name- it can be joined to the domain initially, but after about 15 - 30 mins we'll get an error message when trying to logon.
The error message I believe is:
"The system cannot log you on to this domain because the system's computer account in its primary domain is missing or the password on the account is incorrect."
I haven't seen it happen in a while, but if I remember correctly this is the error message we get -I could be wrong though.
It may also have just been a "domain is not available" message.
Some additional info:
The netbios domain name is diffent then the DNS name ie: "mycompany.tx.com" was not made "mycompany" for netbios, but "mycomp" instead.
Our DFL is mixed mode with some 2000 and some 2003 servers
We used to use WINS, but now we do not.
And lastly we usually add a WINS address along with the dns address in each workstation via "advanced TCP/IP settings" (why I do not know) and occationally I will not be able to join a computer to the domain until I add this WINS address. I know what your thinking, and I will say that I am not 100% all of our WINS server were deactivated.
Any info on how to figure this out or troubleshoot this would be greatly apprieciated. Thanks a lot.
Hi all,
I have DC1 ( win2003 holding fsmo roles ) and DC2. ( 2008 r2) - win 2003 functional level
Whenever my DC2 is restarted without my DC1 running, then DC2 has no services available anymore. Following errors occur on DC2 :
- AD domain service ( naming information cannot be located because: the specified domain either does not exist or could not be contacted )
- DNS ( the server DC2 could not be contacted. The error was: the server is unavailable. )
- DFS not available
- network is in unidentified network & Public network. ( but firewall allows AD, DNS, DFS )
=> is this an expected behavior when an additional DC doesn’t find the DC holding fsmo roles ?
=> Or should I still have my services including dns available in DC2 ?
=> Is the only way to resolve this is to seize all roles on the DC2 ?
Thank you
Hello!
can I bind either a Managed Service Account or a Group Managed Service Account to a DC if the service is running on the DC itself?
Are there any roles / member server types I can NOT bind
1) a MSA
2) a gMSA
