Active Directory Services Can't Connect to Domain
I removed Active Directory services form a server running 2012. I then went to reinstall and reconfigure it, but I keep running into issues. When I launch active directory admin center it gives me an error that it can't connect to any domain, and I can't
make any changes. The local server has already been promoted to the domain controller. Here is the output from dcdiag:

I've been trying to debug errors one at a time, but I'm having a hard time finding any information that pertains to this issue as a whole. Anything you can tell me about this would be great, thank you for reading.
It was the only server in the network, the only dc in the old forest. When I re-installed ad ds I gave the new forest different name, but I guess the old settings are still in the system somewhere conflicting with the new setup? Is there a way to
purge the old setup entirely and start over with ad ds, or am I going to have to re-install the whole OS? Thanks again for the help.
Honestly, the best way to handle this is to rebuild the server. There are many things that are "left behind" when you remove the Domain / Forest from a Domain Controller. In fact many articles will say after using ADMT (active directory migration
tool) you should decommission the original Domain Controller (aka reinstall the OS).
While you could spend more time trying to get that domain controller working, it absolutely is going to be 1) More reliable 2) faster to reinstall the OS on the old domain controller. If you are still leveraging storage, or services on that domain controller,
you will want to back them up, or have a transition plan before reinstalling everything on the server. I have a feeling if you choose to keep troubleshooting this, you will run into more issues down the road.

Having your storage device join Active Directory Services can be relatively straightforward. What do do if the JOIN button fails? This demo goes through a basic checklist from network to server. Demo covers integration between the NSS2000/3000/4000/6000 platform and Microsoft ADS Server 2003.
Part 1 - Network Overview
Part 2 - NSS Configuration
Part 3 - Connecting a share
Part 4 - Server 2003 Administration
Note: Some artistic license was used to make the test environment more easy to illustrate but the principles are the same in a live network.Hi Angus,
Policy Server does not require a specific LDAP schema. During configuration you simply map the LDAP attributes of your schema to the ones that Policy Server supports (e.g., common name, email address, etc).
If you are configuring Policy Server to use an LDAP, it will use the LDAP to authenticate the user (Policy Server does not store the password itself in this case).
If passwords are stored outside of the LDAP (e.g., in a database), it is possible to write a custom authentication provider to authenticate against this source.
Hope this helps,

Active Directory accounts no longer connect to Server
I administrate a small office network.
We have a Windows 2000 Server with active directory and a Windows 2003 Storage Server Appliance. (From Iomega)
After upgrading to 10.4.8 (it seems), our Mac integrated to the Active Directory has had problems connecting to the storage server.
When attempt to connect to smb://storage (the 2003 server appliance) we get a Error code -36 -- could not be read or written.
This only happens when logged into an AD account. Local accounts on the machine access the server as normal.
Also of note, the AD accounts have no problems accessing shares on the 2000 server.
Any ideas why this is only effecting AD accounts and a solution?There are a couple of things you can check...
1. Check to make sure that the SMB signing option is disabled for the Windows 2003 Storage appliance. This can be done in the local group policy on the Server.
2. If it is a storage appliance, you should be able to run Microsoft's Services for Macintosh. This would give you AFP on the file server - a potential way to eliminate the need for using SMB on the Macs.
3. Use a 3rd party software on the Windows 2003 Storace Server called ExtremeZ-IP by Group Logic. It is a full featured AFP/IP file server for Windows (replacing SFM). We have an HP DL380 NAS device on our network (running Windows 2003 Storage Edition) that has 1.5 TB of storage for our MAc users. We use ExtremeZ-IP... I have nothing bu great things to say for it... -

Why the error occurred ?
What is the resolution to this error ?
Appreciate any help. Thanks.This error message is telling you that SGD failed to find any site objects in your AD tree. This should not stop users from logging in, it will just mean that SGD will not be able to work out which AD site is local to the SGD server.
If you are not using sites in your AD setup, then you do not need to worry about this.
Hope this helps,

Changes in Microsoft Active Directory Services into a file
I am in need of sample code to capture changes in Active Directory services into a flat file.
Here is my requirement:
I would like to capture user information changes from the Active directory server into a flat file.
For an example, When a user is newly created in Actives Directory Server, I need to Capture that user info and write into a flat file. Similarly for update and delete user in Activer Directory server, i need to capture the changes and write into a file.
Would appreciate, if any could help me on this
Thanks in advance
Thanks

DNS The Zone cannot be deleted - the active directory service is not available
Hello TechNet Members,
As you can see from the Summery, I got this message when I'm trying to delete DNS Zone.
It's not matter if the DNS Zone newly created or its an Old One.
After this message the computer is telling you "The Computer is about to make Restart".
It's so strange and i really don't know what to check first.

I did Demotion for one of the DC to troubleshoot, but with no luck i'm back to the same point i started
I tried to delete the brand new Zone from the commandline using DNScmd it's still not working and the computer is reboot himslef.
I've checked the permissions from the ADSIEdit.msc:

Strange DNS, Group Policy & Active Directory Issues - Can't track down root issue!
For the last few weeks, we've been getting complaints, from our developers, about not being able to authenticate on various systems. The issues were hit & miss but still problematic enough to warrant our looking into it. It seems to be getting
worse... I now have new servers that aren't getting group policy updates. They may get some, like the list of local admins but won't pick up NTFS permissions for folder-access. Those that pick up the AD group full of local admins have trouble
authenticating members of the group. Some were showing event log entries regarding authentication issues due to being unable to contact an AD DC. We reloaded that DC but many of the issues still persist. At this point, I'm running
out of places to look for ideas. I've spent the last week looking up Event Log IDs and looking though their meanings and possible remedies but, again, the issues persist. It doesn't seem to matter what the OS is. We've been seeing
this on 2008, 2008-R2 & 2012-R2.
Here are some examples of events I'm seeing. I can't figure out the root cause(s).

Note that these servers are sitting in OUs that are full of other servers that don't have these issues. These GPOs have been in place for years. I suspect there's a deeper issue with AD, GP or a combination thereof. The group policy issues
seem to only affect freshly loaded servers...Hello,
assure that no firewall is blocking connection for AD required ports as listed in
https://technet.microsoft.com/en-us/library/dd772723(WS.10).aspx
You have error about not connect setup from AD sites and services with the used subnets in your network and linking them to the correct site, please check this in AD sites and services and also have the DCs placed correct to the site they belong to.
"During the past 4.20 hours there have been 83 connections to this Domain Controller from client machines whose IP addresses don't map to any of the existing sites in the enterprise. Those clients, therefore, have undefined sites and may connect to
any Domain Controller including those that are in far distant locations from the clients. A client's site is determined by the mapping of its subnet to one of the existing sites. To move the above clients to one of the sites, please consider creating subnet
object(s) covering the above IP addresses with mapping to one of the existing sites. The names and IP addresses of the clients in question have been logged on this computer in the following log file '%SystemRoot%\debug\netlogon.log' and, potentially,
in the log file '%SystemRoot%\debug\netlogon.bak' created if the former log becomes full. The log(s) may contain additional unrelated debugging information. To filter out the needed information, please search for lines which contain text 'NO_CLIENT_SITE:'.
The first word after this string is the client name and the second word is the client IP address. The maximum size of the log(s) is controlled by the following registry DWORD value 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters\LogFileMaxSize';
the default is 20000000 bytes. The current maximum size is 20000000 bytes. To set a different maximum size, create the above registry value and set the desired maximum size in bytes."

As the output will become large, DON'T post them into the thread, please use Windows Sky Drive(with open access!)
https://skydrive.live.com and add the link from it here. Also the /e in dcdiag scans the complete forest, so better run it on COB.

Please help me to delete the Dead domain (was a domain the in parent forest, but to child domain), which had trust with parent domain as well. It showing presence in Active Directory Domains & Trust also.
Please show me a path to remove dead domain.
Thank you.
-ShamilHi,
To remove a domain from a forest, we need to demote every Domain Controller in this domain or perform
metadata cleanup using ntdsutil.exe tool.
We can run Dcpromo.exe to demote a DC, please remember to select
This server is the last domain controller in the domain check
box when you are demoting the last DC in
the domain.
Please make sure that DCs in this domain don’t holder any forest-wide FSMO roles.
If all domain controllers have been taken offline without demotion process, we can
perform metadata cleanup to remove this domain.
You can use ntdsutil.exe tool to connect to the
Domain Naming Master role holder, then remove the specific domain from the forest.
For more information please refer to these articles below:
How to remove orphaned domains from Active Directory

I hope this helps.

ACS Integration with Microsoft Active Directory Services
Hello Everyone,
I've been tasked to design the integration of ACS with MS AD. What I want to know is the below assuming I have a software ACS or a ACS device and the protocol for authentication is Radius
- What is the criteria for the AD to integrate with ACS software of appliance
- Should that AD be hosted on the domain controller or not?
- If not, on what (Domain Controller, Tree, Forest, Branch, Flower, Fruit ) should the AD be hosted on?
- What will I have to do to authenticate users logging into Cisco Security Manager with ACS integrated with AD?
- Are there any other dependencies that I will have to categorically mention in my design document?
Thanks,
RishiIn ACS v5.x, there is a screen for integrating the ACS with AD.
(Users and Identity Stores > External Identity Stores > Active Directory)
Just enter the local domain name (domain.com) and a valid AD administrator account username and password, and the ACS will connect to the domain. This allows you to use existing AD credentials to login and administer your network devices.
Tying the ACS to AD really only takes one screen and less than a minute, but you will still have to tell the ACS which AD groups get which permissions (for example, read-only or read-write access), and you will have to setup a search sequence (Users and Identity Stores > Identity Store Sequences) to tell ACS to first look at AD for credentials, then check the local ACS user database for valid accounts. The permissions part is still fairly quick, and it only takes me about 45 minutes to build an ACS from scratch including all AD integration and custom RADIUS attributes for some of our devices.
The authentication would occur like this:
User SSH/telnet/console to device
Device contacts ACS using TACACS or RADIUS
User receives login prompt and enters AD credentials
Devices sends credentials to ACS
ACS validates credentials in AD
ACS sends authentication OK message to Device
Device logs user in.
Command Authorization looks something like this:
User enters a command
Device sends command authorization request to ACS
ACS looks at which AD group the user belongs to and looks up permissions configured in ACS for that group
Based on the permissions you have assigned, ACS either sends an allow or deny message to the Device
Device allows or denies the user command.
Criteria: We use an ACS 5.2 virtual machine and have had it work perfectly with Server 2003 and Server 2008.
AD is hosted on our local domain controller (Bonus: no planting of flowers required!)
Dependencies:
Issue: The Device looks to ACS. ACS looks to AD. If AD fails, users cannot use their AD credentials to login.
Device ---> ACS ---> AD
Solution: Configure the Device to look at ACS first, then a local table if ACS is not available. Also, configure the ACS to look at AD first, then a local ACS account list if AD is not available. (You can configure local user accounts on the Device and in the ACS)
Device ---> ACS ---> AD
Device ---> ACS ---> AD ---> ACS local
Device ---> ACS ---> AD ---> ACS local ---> Device local
The new version of Cisco ACS is UNIX-based, and you can download a free trial to load up and try before you buy. It is far FAR superior to the old ACS v3.3 that we had for years.
I hope this helps for your design document!

Windows Server Active Directory services
Hi,
We have installed Windows server 2008 R2 as a primary domain controller.
the domain controller "xxxxxxx" (2008R2 SP1) gets freeze intermittently and at the time of issue we are not able to ping and take RDP session of this server from any other server.In the
event log : 4015
The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error.
Kindly advice how to resolve this issue.
Thanks,
BalajiHello,
Could you check your servers hdd, nic and another services pls. Also this error (4015) occur DC is not respond requests
from the DNS Server.
Check your DNS functionality (Dcdiag /test:DNS) and refer these
articles please.
DNS Event Id: 4015, 4513 and 4514
Event ID 4015 — DNS Server Active Directory Integration

Main points: Be sure your local time is being updated by a time server on your network, be sure that all devices are syncing with the same NTP server.
Pre add your computer you want to bind in your domain.
Key: in Directory Utility, choose to authenticate against a known server. So under the Administrative tab choose "prefer this domain server" and enter in the DNS name of a DC in your domain. Also uncheck authentication with any DC in the forest.
Now bind and click Ok.
Now in Directory Utility, click on Search Policy, and add servers in the Authentication tab by choosing Custom Path. Click the + and you should see your domain or multiple domains in your forrest listed. Add them appropriately. In some configurations, you may want to do this for "Contacts".
You can now go back into the Active Directory plugin, and choose to authenticate from any DC in the forest, and remove the selection that allows only authenticating against one server.
Sorry for the lack of deep explanation, but if you are at the point where the AD and DNS is working fine, then this should be pretty straightforward and to the point.alex.est wrote:

The only thing I've seen thus far on the negative side is the recurring "can't connect to server" errors.
A reset seems to help, but I didn't have this with previous versions.
Anyone else seeing this?
ScottI'm having the same issue. It only seems to happen with 3g, no issues with wifi. Resetting the iphone helps for a few minutes then the error returns. Was having the issue until today (Feb 1, 2009). Now seems to be working normally. Hope Apple/at&t have figured this out and it won't come back.
