User profile Service
↧
The specified account already exists.
HELP.
I am in a twist here as to what is going on and am unable to resolve.
History.
Two of our Domain Controllers Tombstoned due to network card issues.
I attempted to demote the controllers but had some access issues. I believe at least one of them is now ok and has demoted successfully (I believe). I tried to re-join the domain but kept getting "the specified account already exists" and it would not re-join. I checked DNS objects etc and there were no remnants of the server anywhere. Other Domain controllers cannot see this computer either.
I eventually deleted the Server completely and built another VM using the same credentials as the original. However, when I attempt to join the domain I get the same issue "the specified account already exists".
I really don't know what to do next and need to get this resolved soonest as we are due to migrate objects in AD to a different domain.
Please could someone offer any advice.
Thanks in Advance.
Regards.

how to prevent reuse of account names
The goal here is to prevent accounts from being created with the UPN of an account that existed in the past. So if employee A leaves in 2015, that account ID should never be used again. Is there a secure way of creating an empty, permanent account with no license that would successfully block new users from using the same name when they create their accounts?

Replication access denied
Hi Support,
We have two Windows 2012 Standard DCs.
We did not make any recent changes.
When checked replication today we have seen the below error
Repadmin: running command /showrepl against full DC localhost
Default-First-Site-Name\AD1
DSA Options: IS_GC
Site Options: (none)
DSA object GUID: 653b6bb0-39bc-4610-a4a7-b08248b940d6

DsBindWithCred to localhost failed with status 5 (0x5):
Access is denied.
The other DC, AD2 is fine. That dc is having inbound replication from the problematic DC. AD2 is the primary DC.
Please let me know how do I troubleshoot this.

Enable Remote Desktop access for Domain user
On a newly setup Windows 2019 Server Essentials domain, a user requires to RDP into their workstation.
I have added the user to the Builtin Remote Desktop Users group but they are still unable to RDP into either the server or their workstation.
If I add them to the Builtin Administrators group they can RDP into the server, but not their workstation.
Any suggestions please?↧
Account policy settings not being enforced
Hello, we have a Password policy defined in the Default Domain Policy enforced in AD which is working on all our Windows 2008+ machines except recently deployed Windows 2016 machines.
On those machines which are in the appropriate OU, running gpresult /V shows that the Default Domain Policy is applied successfully. Running RSOP also shows that it is enforced. However, if I run "net accounts" from an Administrator command prompt it doesn't show the appropriate settings. Additionally, access the Local group policy, doesn't show the settings, but they are greyed out.
I have removed one of the machines from the OU where this is defined to a test one which blocks inheritance and the settings are available in local policy to change, but are set to Windows defaults.I have gone through all the Group Policies to see if the settings are defined elsewhere and they are not.
The scope of the Default Domain Policy covers the machine.
Does anyone have any idea why the password policy isn't applying correctly? and how to fix it?
Thanks

Service account permission
Hi guys,
Scenario: I have a service account that is granted permission to run a script on a server. I've noticed that when other users who are non-domain admin sometimes use the credentials for the account to run a script they get access is denied.
I come in and run the same exact script with the same service account credentials and it works. Funny part is once I run it and it works then when they try it works again till they have the issue again. The account is not locked, disabled or anything like that whenever this happens. Password is set to never expire.
This does not make sense to me because they are doing "run as" and using the same credentials I'm using.
Is there a permission that is needed from AD or maybe on the server for other users to be able to use the credentials?

Is Windows 2019 released or not?
Hi,
Is it already available to use Windows 2019 to change my domain controllers?
Is the procedure for installing in a domain and changing DCs the same as what we usually do?
- Promotion new DCs
- Transfer functions
Thank you.

Installation of new 2016 servers to replace the 2008.
Hi,
We have a domain that already has a 2016 server in the forest and there are still two servers 2008 left.
I want to remove these 2008 and install new 2016 servers.
I will do the promotion myself and transfer the functions to the new ones.
Are there any other tasks that need to be performed? How to update GPOs? Etc...
Thank you.

CA not updating revocation list of superseeded CA certificates
Hello,
I have a Enterprise Sub-CA running on Server 2012R2. The root is an offline CA. I have a history of 6 CA certificates (0-5) of which 4 & 5 are revoked. There are still many valid certificates issued by certificate no. 3 in the field. The problem is, that the CA is not issuing revocation lists for certificate no. 3 anymore and therefore I'm getting certificate errors. The CA is issuing revocation lists for ca certificates no. 0,2 and 5 though. I don't mind no. 1 as there were no certificates issued by this certificate, but I have to have revocation lists for CA certificate no. 3. The revocation lists are not issued automatically or if triggered by hand.
Any idea?
Thanx

Unable to create user accounts until DC is restarted
We have experienced 3 times lately where we have been unable to create user objects in Active Directory. The first two had the same errors. I'm not sure if the third one is related or not.
I have 4 DC's, two in each of two sites. One of the Domain Controllers, DC1, has all the FSMO roles They are all Windows 2012 R2, but the Domain and Forest Functional Level is at Windows 2008 R2 until later this week. We have a single domain forest. We have about 650-700 actual users, so even with shared and special user ID's, we probably have less that 2000 user objects. Not a large Active Directory structure.
While I first noticed the problem when working in Exchange, this is an AD problem. Almost 6 weeks ago, I suddenly was unable to create a user account when trying to create an Exchange mailbox. The error in Exchange was "Exchange couldn't find any usable connections to the Active Directory server DC1.domain."
In the System log on DC1, there were numerous Event ID 16642 error events from Directory-Services-SAM:
“The account-identifier allocator was unable to assign a new identifier. The identifier pool for this domain controller may have been depleted. If this problem persists, restart the domain controller and view the initialization status of the allocator in the event log.” After finding very little about troubleshooting this error, I restarted DC1. Once DC1 came back up, I was able to create user objects again.
Early last week, I experienced the same thing with the same errors. I restarted DC1 again, and again I was able to create objects normally.
I was off last Friday, but received an email from a colleague that we were again unable to create user objects. They restarted DC1 and were able to create users again.
I looked through the Event logs on DC1 and did NOT find the Event ID 16642 from Directory-Services-SAM. I did not find anything in the Application or System log that looked like an explanation for this inability to create users on Friday morning. This time, I looked at the Directory Service log and saw error Event ID 1519 repeated many times:
"Internal Error: Active Directory Domain Services could not perform an operation because the database has run out of version storage."
I saw a Microsoft blog about version storage at "https://blogs.technet.microsoft.com/askds/2016/06/14/the-version-store-called-and-theyre-all-out-of-buckets/". This blog discussed increasing the maximum size of the version store, but it related the need for this with information that would be found in error Event ID 623. DC1's log does not contain Event 623.
Unfortunately, the Directory Service log went back only a few days, so I could nor look for what might have been in there during the time frame of the first two instances of being unable to create users.
Can anyone offer me any help with what I need to do to prevent this situation from recurring?

How to make LDAP SSL call using DsBrowseForContainerW API
Hi,
I am using DsBrowseForContainerW( ) to load all container (OUs ) from given domain.
Internally Its using LDAP Non SSL call to read data from domain controller. But I want to use LDAP SSL communication to read data from Domain Controllers.
How can I achieve this?
case-1 : ADsPath = "LDAP://Domain100.Lab/DC=Domain100,DC=Lab" working fine and LDAP Non SSL calls
case-2 : ADsPath = "LDAP://dc12.Domain100.Lab:389/DC=Domain100,DC=Lab" working fine and LDAP Non SSL calls
case-2 : ADsPath = "LDAP://dc12.Domain100.Lab:636/DC=Domain100,DC=Lab" NOT working fine
LDAP Non SSL port = 389
LDAP SSL Port = 636
Code :
DSBrowseInfo dsbi = new DSBrowseInfo();dsbi.cbStruct = System.Runtime.InteropServices.Marshal.SizeOf(dsbi);
dsbi.pszCaption = caption;
dsbi.pszTitle = title;
dsbi.pszRoot = ldapPath;
dsbi.pszPath = sResult;
dsbi.cchPath = 1024;
dsbi.hwndOwner = hwnd;
if (user != null && user.Length > 0)
{
dsbi.pUserName = user;
dsbi.pPassword = password;
dsbi.dwFlags |= DSBI_HASCREDENTIALS;
}
int ret = DsBrowseForContainerW(ref dsbi);
In case-3, its giving error as unable to connect to domain with given user name and password.
Please help me to solve the issue. How can achieve LDAP SSL communication by using DsBrowseForContainerW() api.
Thanks & Regards

DNS - Server addressess
Hi All,
I am having some difficulty with client machines not logging into the nearest Domain Controller at their local site. For example some of our client machines in HQ connect to a satellite site some distance away. Dito for some clients on satellite sites who sometimes connect to other satellite sites. Information from client machines has been gathered via CMD and SET command, the logonserver shows Domain controller.
Our sites and services have been verified, configured correctly and have the appropriate IP Subnets setup. The costs etc are all setup as per Microsoft recommendation.
I am now looking at DNS configuration on the Server network cards. The way it is set-up now is that we apply a static IP address on all servers and click the Radio button "Use the following DNS server addresses:". The addresses we use are the local DNS server and a DNS server that points to the replication DNS server, for example: a Satellite Server would have its own DNS IP settings configured as Preferred and the HQ DNS IP Settings would have the Alternative settings set. I am beginning to doubt if these setting are correct as it seems everything in Sites and Services is correct.
Any help or advice on how I can overcome this problem would be very gratefully received.
