DFSR replicaion problem between domain controllers
I have 2 domain controllers running server 2012 and recently noticed a lot of errors about replication between 2 of them
i demoted child controller and promoted it again for DC and issue still occurs
so far i noticed that when browsing network and looking for shares on main DC i can see SYSVOL folder there
but it is missing on the other one - it is present in c \ windows but not visible in shares \
also domain folder is empty on the child DC
when i run dfsrmngr and run the diagnostic it doesn't show errors in status also it says that it is enabled
also when trying to manualy create pair of folders to replicate the contents it says at one of the steps it is already used ....what would be the best
thing to do at this point o have replication issue solved ?

Communication issues between domain controllers
Hi everyone,
I am experiencing some problems in communication between domain controllers in our organization
We have three domain controllers, one of them is a Windows 2003 server service pack 2 which is physical (controller A), another which is Windows 2008 Service Pack 2 (controller B), also physical, and a third one (controller C) which is a Windows 2008
service pack 1 and is virtual.
I have problems with this last DC, it won't respond to pings, or DNS query. I can't Access it by remote desktop client even when it is enabled. I cannot update it, it prompts error messages if I try to do so.
This problems are solved if I reboot it, it will work fine some hours or days, but not much longer. I have checked event viewer and I didn't found any message about this.
I read some time ago it would be great to have a DC in a virtual machine, so I did it, but is it right?
Do you know what might be going on with it? would depromoting it and seting it up again the best solución?
Thank you very much.
Best regards.
David.This sounds like a NIC issue, which is odd since it is a virtual machine. Have you checked the host for any logs about the client?
I think the first thing I would do is destroy the current virtual NIC card and add a new one. Since this has nothing to do with Active Directory I would also suggest you post this in a forum of for the Host (VMWare or Hyper-V).

Unable to Sync SYSVOL Folder between Domain Controllers
Good Afternoon All,
I have the following issue on my current domain configuration, I say current as we are seeking to go to Server 2012 R2 within the next few months, but for now, we are at the 2008 R2 functional level.
We have three Domain Controllers namely Server-001 to 3, with Server-002 holding the PDC Emulator Role. Now when policies are created or updated through GP Management, I have noticed that they sync without issue between Server-002 and Server-003, but not
Server-001. In the SYSVOL Folder in each DC, the folder totals in policies are as follows:
Server-001 - 72 Folders
Server-002 - 96 Folders
Server-003 - 96 Folders
So here, it can be clearly seen that there is some sort of replication issue between Server-001 and the other controllers. I have researched and read several articles and opinions regarding the same issue and have ran many of the commands outlined including
repadmin, dnslint, gposync, etc. with the only output displaying errors being gposync. I have checked all the event logs for each DC with added focus on the DFS Replication Logs and have seen no errors regarding replication on Server-001 which is the server
at fault, but have noted that it appears that Server-001 is only replicating to itself, while Servers -002 and -003 are syncing/replicating between each other. I created a text document in Server-002's SYSVOL Folder and checked in Server-003's and verified
that the document successfully synced across, but on Server-001 nothing happened. I did some research on the issue and came across non-authoritative sysvol restore as an option, but when I tried this on Server-001 via ADSI Edit, I noticed that the following
path:
OU=Domain Controllers>CN=Server-001>CN=DSFR-LocalSettings>CN=Domain System Volume
is missing. Initially, DSFR-LocalSettings was missing as well, but I re-created it. I then attempted to re-create Domain System Volume, but when I tried entering the Replication Group GUID, I got an error that "one or more of the values are not in the
correct format", even though this is the same GUID used on the other two DCs. I tried changing the value to octet, hexadecimal, etc. but nothing worked. i still got the same error. I am convinced that this is where the disconnect lies, but with no possible
idea how to fix this broken section, I am unsure how to further proceed. We were going to demote the server, bring up a 2012 R2 unit and have it seize the roles, but I convinced my Systems Administrator for us to try and see if there is a fix available before
commissioning a new server. As is, group policy is somewhat broken as policies either do no get applied at all, or, get applied to certain groups or OUs.
If you are interested I can forward you our DFSR Logs from each server, along with any other reports that I have run in the hopes that someone will be able to assist. I hope that I have been as clear as possible and have provided as much information as is
possibly required.
Thank you all in advance.Hi,
To perform non-authoritative synchronization for DFSR-replicated SYSVOL, the following article can be referred to for more information.
How to force an authoritative and non-authoritative synchronization for DFSR-replicated SYSVOL (like "D4/D2" for FRS)
http://support.microsoft.com/kb/2218556/en-us
Besides, we can use dcdiag command to check the health of the DC.

Difference between domain controllers and group policy objects in GPMC
Hello,
Am in confusion, someone can tel me the difference between
1.Domain controllers>default domain controller policy and
2.Group policy object>default domain controller policy
In Group policy management console and also i would like know where to define these categories. I normally use second option.
I have attached screenshot for your information.
regards,
Dharanesh,This first/upper item is a link to the GPO, the second/lower item is the actual GPO.
(notice the link, has a shortcut arrow showing)
by default, when you double-click on a link, a message will display which says "you have clicked on a link....." and the messagbox offers a checkbox for "do not display this message again..."
Effectively they are equivalent to a shortcut-to-a-file vs. the actual file.

Excessive Traffic on Port 445 between 2 Domain Controllers
Hi, my company has over 45 DC's across about 25 sites worldwide. We are noticing a lot of traffic using wireshark and Network Monitor on Microsoft-DS port 445. I have been searching if this is normal and what I see is that it is used for SMB File and
print sharing. Well, I don't have any file shares on these DC's other than the normal admin shares and sysvol share. I don't believe this is replication traffic since these 2 servers are not replication partners. I have checked sites and services to make sure
the intersite and intrasite connections look good. This traffic is constant over weeks and it is about 1 GB an hour between the 2 servers. This would not be a big deal if this was just on the local LAN but it is over the WAN and
that saturates the line. Should 2 DC's be talking that much that are not even replication partners? What type of traffic could it be. I am at a loss for troubleshooting this. I have done packet captures but that really does
not tell me much ( that I can read anyway). Oh, I have run AV scans alos and finding nothing.
Any help would be greatly appreciated.

SteveActually, DFS/FRS/DFSR replication is not related to NTDS replication. It uses a directory change notification event to trigger replication to a replica, and that is to all DCs in the domain. That's why you can have SYSVOL replication problems but AD replication
of the partitions do not have problems, such as when you create a user on one and it replicates to it's NTDS partner.
Below is a summary. You can read about how the whole process with NTFRS/DFSR works in the links below, if you like:
Introduction to Administering DFS-Replicated SYSVOL
"DFS Replication technology significantly improves replication of SYSVOL. ... When a change to a file occurs, FRS replicates the entire updated file. With DFS Replication, for files larger than 64 KB, only the updated portion of the file is replicated."
"To replicate only updates to files, DFS Replication uses an algorithm called remote differential compression (RDC). RDC detects changes ... without having to replicate the entire file. RDC detects insertions, removals, and rearrangements of data
in files. The DFS Replication service monitors SYSVOL, and, if a change occurs to any file that is stored in SYSVOL, DFS Replication automatically replicates the file updates to the SYSVOL folders on the other domain controllers in the domain. "
http://technet.microsoft.com/en-us/library/cc794837(v=WS.10).aspx
How FRS Works - Windows 2003
http://technet.microsoft.com/en-us/library/cc758169(v=WS.10).aspx
DFS Replication: Frequently Asked Questions (FAQ)
http://technet.microsoft.com/en-us/library/cc773238(v=WS.10).aspx
I think 316 MB in SYSVOL is a good amount of data. What is in there taking up that much space? Is something using SYSVOL to store it's data, such as an app that's constantly changing data?
The reason I'm asking is that this could be the cause of the issue, since if it changes on one DC, then it replicates, then another change occurs, etc., and it keeps going and it appears that a ton of data is being moved back and forth.
Quick story - I remember a customer was using SYSVOL to store data so they can access it across the WAN link. He said he did it because of its "cool" replication features. I said, yea, but it's meant for domain data (GPO policies, templates, etc.)
and not for custom data. Create a DFS share for that so it works independently of SYSVOL.

Replication and AD Domain sevices errors between 2 Domain Controllers
Hi,
I've a 2 Domain Controllers (NJ-DC1-2K8 and NJ-DC2-2K8) setup in VMware Workstation 10. Recently, I've run into different errors in regards to Replication, DNS and AD Domain services. Both of my DC are setup with static IP pointing to each other for fault
tolerance. Initially, One of my DC had a lingering object error which I was able to fix after spending some time. The next day, when I tried to replicate 2 DC, the number of errors grew. Ran dcdiag, it produced a list of crazy errors that I never saw before.
I'm a newbie to the server environment, trying to gain knowledge so I can't get those errors sort out even I tried a lot. I read a lot of online articles on different forums like here Microsoft TechNet trying to overcome this problem but didn't work. I even
removed DNS role and re-added it but same problem. I guess removing the DNS role doesn't remove everything related to DNS. I'm going to upload pictures here of the different errors through the commands I got. I would appreciate if someone can help me to get
it fixed.
Other than that, I also would like to know what is the best way to remove DNS, AD Domain Services and then reinstall them without demoting the server. What are some of the things I would have to keep in mind before doing that. How can I make sure that doing
this wouldn't impact in AD data loss like user account, GP Policies, Computer account and etc....?

Please someone go through these different errors and walk me through exactly what I got to do to fix them.
ThanksHi,
Actually, I made copies of those VMs to my external usb 3.0 hdd, so I can load up some of the VMs from it than from my internal hdd since it would freeze on my internal one sometimes. Copied ones worked fine for few days until recently when I started having
these different issues. I did look at USN rollback and applied the fix, didn't work. For the past few days, I been spending endless hours on fixing them but it doesn't look like they are going to be fixed. It's driving me crazy and the bad news is that I've
no backup of my data. I got 2 DC and both have these issues.
Building new domain controllers in VMs won't be a problem for me but I'm worried about losing my AD database in both DCs which includes user and computer accounts and a bunch GPOs.
I'm a newbie to the server environment. Can you please walk me through on exactly how can I save AD database if possible before I start doing the cleanup process on both of my DCs. I read some articles online which provide instructions on how can I cleanup
the AD with Metadata and take both DCs offline but it's all confusing to me. They don't explain anything about saving AD database rather demoting bad DCs. If you know a fix for my DCs that I can apply, so I won't have do it all over and save time. Please let
me know step by step process or whatever you could help me to bring those 2 DCs backup.
Thanks -
Problem creating external trust between domains
Hello,
When I try to create one-way incoming external trust between 2 domains (to DomainA from DomainB) in separate forests I get this info:
This domain already has a one-way trust relationshp with specified domain.
But I cannot see it on the list of trusts either incoming or outgoing (in both domains).
For sure trust was never setup before.
In DomainA there are several other external not transitive trusts with other domains. But for sure DomainB do not have any incoming or outgoing trusts on list. Name resolution betwen domains is OK. I can ping domain name on both sides.
Any help is welcome.
Darek.Hi,
Were there error events logged in Event Viewer? Besides, did we open necessary firewall ports for creating external trust?
Regarding firewall ports, the following thread can be referred to for more information.

DFSR failed to contact domain controller
Im having an odd problem with DFSR group we created to replicate web content between two of our web servers.
In event viewer we have this event 1202 for DFSR.
"The DFS Replication service failed to contact domain controller to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can
be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues.
Additional Information:
Error: 160 (One or more arguments are not correct.)"
In the DFSR logs I see this.

When I run "dfsrdiag pollad":
[ERROR] PollDsNow method executed unsuccessfully. ReturnValue: 12 (0xc)
[ERROR] Failed to execute PollAD command Err: -2147217407 (0x80041001)
However I can run "dfsrdiag dumpadcfg" and it outputs everything fine.
We don't have any other problems with AD. It seems like this started after we installed KB2467173 & KB2538242. We are going to uninstall those and see if it works.I can successfully run "dfsrdiag.exe dumpadcfg" and it outputs the entire config. Why does "dfsrdiag pollad" fail then if the config can be read.
Why did it work before I rebooted the server? In both cases it broke after rebooting.

Windows 8.1 Pro Cannot Connect to Domain Controllers through Wi-Fi
I have a domain joined Surface 2 Pro running 8.1 Pro Update that is suddenly unable to connect to the domain controllers on the local network. The machine is fully patched. I'm guessing that it is some network level security issue because the wi-fi is working:
It has no trouble connecting to my Wi-Fi hotspot on my phone.
It has no trouble connecting to other Wi-Fi at coffee shops etc.
It is connecting to my home Wi-Fi and gets an address from DHCP on the domain controllers, but can't ping the DCs, access the DCs through remote desktop even using their IP address.
It can ping the router and ping systems on the internet using their IP address rather than hostname.
I can fully access internet systems if I point it at DNS on the router but still cannot access internal systems by name or IP address.
The Wi-Fi network shows as a public network rather than a domain.
It will work fine when it is docked and using the dock's ethernet adapter.
If I use VPN to loop back through my router then I am able to fully access local systems.
None of the other systems on the network are experiencing the same issue.
I have tried the following which didn't work:
Switched off the Windows Firewall on the Windows 8.1 system and a domain controller.
Network Troubleshooting - which told me that the network seems OK but the DNS servers are not responding.
Uninstalling the Wi-Fi device and restarting the system to re-install it.
Resetting TCP/IP.
I am not aware of any changes, but the system did install System Hardware Update 8/07/2014 (again!) but I can't recall if that was when the problem started or was just a coincidence.
Any suggestions?
Thanks,
Richard
Richard-FHi Richard,
Apologize for my slow understanding.
I thought as it could obtain IP address from the DC, it should have connections between them.
For the current situation, you may take a try to disable the firewall on the DC, then check the port that used by AD environment is all available,
Active Directory and Active Directory Domain Services Port Requirements, you could take use of this tool:
PortQryUI - User Interface for the PortQry Command Line Port Scanner
If all available and issue still insists, then issue here seems to be restricted with the wireless router. You may try to contact the router side and see if they could offer any further useful information regarding this situation.
Best regards

I have 2 domain controllers running 2003 server, server1 and server2. I ran dcpromo on server1 and removed AD and removed him from the domain and disconnected from network. I then added a 2012 server
with the same name and IP address server1 with no problem. Replication from sites and services work fine on both controllers.
The new 2012 server1 is GC. I transferred all FSMO roles to server1. Again no problem and replicating using sites and services. AD on server1 is populated correctly.
Now what I had intended on doing was a dcpromo to remove server2 from the domain so I can then add another 2012 server. That is when I get the: "The box indicating that this domain controller is the last controller for the domain
is unchecked. However, no other Active Directory domain controllers for that domain can be contacted.
I have DNS installed on both servers and both look good with replicating there. Strange thing is when on the 2012 server within DNS if I right click and connect to another DNS server I can add server2 just fine but from server2 adding server1 it tells me it
is not available.
Help please!Hi,
As there is server 2012 DC (SERVER1) DC is operational in a domain then "This domain controller is the last controller for the domain" should be remain unchecked when you demote SERVER2 DC.
If you are getting error "Active Directory domain controllers for that domain can be contacted" while demoting SERVER2 DC then check the DNS pointing on both as per below article, disable windows firewall on all DC, less possiblities but worth to check if both
are different site then check the ports are open on firewall.

http://social.technet.microsoft.com/wiki/contents/articles/584.active-directory-replication-over-firewalls.aspx
run “ipconfig /flushdns & ipconfig /registerdns“, restart DNS server and NETLOGON service on each DC and try to demote server2 DC.
If issue reoccurs, post dcdiag /q result.
NOTE: If initial replication was completed between both DC (new 2012 and old DC) then you may remove the server2 DC from Active Directory forcefully (DCPROMO /FORCEREMOVAL) and perform metadata cleanup.

OIM provisioning to Multiple Domain Controllers of a single Domain
Hi experts !
Our client has offices in different parts of country and they are using MS AD. We have to integrated this AD with OIM. The issue we are facing is that there is a cluster of domain controllers (DC) at each location for example NewYork, Dallas and Ohio and OIM is being deployed in NY. All the DC at all location are part of a single domain "example.com" and they is no child domain.
Now if a User Administrator in Ohio logs in to this central OIM online and creates / modifies user profile of a user in AD, it means that the OIM will create / update the user profile in the DC placed in NY and through AD replication, it will be pushed to Ohio.
As the communication between few sites is not reliable, thus managers at these locations will have to bear the delays if the replication between DCs takes time even when they have modified the resource profile in OIM.
Is it a possibility that the user administrator at location A, when modifies the user resource profile, the modifications is carried out in the DC of location A? for example, if the administrator in Ohio logs in, whenever, he changes the profile, OIM modifies the profile in DC placed at Ohio?
I have gone through "Configuring the Connector for Multiple Installations of the Target System" in MS AD connector Documentation but i am uncertain whether this "target system" means DC of same domain or different child domains?
Any help / idea would be really appreciated.
Best Regards.

Edited by: Zia on May 8, 2011 11:22 PMthank you for your reply sir
initially i was of the idea to place OIM servers at each location with DB at a central point. However, there are more than a dozen such locations! have you come accross any such scenario where more than 12 machines running OIM at different places point to a central DB? i was a bit reluctant in proposing such design due to network instability. So we decided to deploy OIM at a single location in cluster mode and admins at each location will access this single instance (cluster) over the WAN. This cluster will populate domain controller at this specific location and will be replicated through AD replication.
But now the analysis team has pointed out the problem scenario as i have mentioned in my earlier post. so we are in a bit fix how to handle this situation :-s -
DFSR replication stopped between sites after all servers updated (Event 1202)
Hello,
I'm afraid, i will greatly appreciate any help on this one.
I'm working on it since 2 days without success (I read many thread without help).
So the fact:
I have 2 AD (2008 R2) on site 1 and 2 AD (2008 R2) on site 2.
I have also 2 files servers (2008) on site 1 and 2 files servers (2008 R2) on site 2.
The files servers run DFS system.
DFS Namespace is host on all AD.
DFS Replication and share are on all files servers.
After update all my servers. I got a big problem.
Communication between files servers and AD of site 2 isn't working properly now.
By this fact, DFSR is not working anymore between site 1 (all seem fine on this site) and site 2.
DFSR on site 2, pop this events all time:
Event 1202 - Source DFSR
The DFS Replication service failed to contact domain controller to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can be caused
by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues.
Additional Information:
Error: 160 (One or more arguments are not correct.)
Event 1055 - Source GroupPolicy
The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following:
a) Name Resolution failure on the current domain controller.
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).
>dfsrdiag dumpadcfg
Operation Failed
>dfsrdiag pollad
Operation Failed
On ADs site 2, dcdiag /e don't reveal any issue.
I tried to install hotfix ref on this thread (without help) -> https://social.technet.microsoft.com/Forums/en-US/7d486eb5-6b03-471c-a4dc-65826e712fc3/dfsr-replication-event-id-1202-the-dfs-replication-service-failed-to-contact-domain-controller?forum=winserverfiles
I don't have issue with DNS (nslookup work fine).
Firewall are disable on all servers.
My problem looks a bit like here (but he don't speak about 2008 R2 - old article) -> blogs.technet.com/b/askds/archive/2011/04/08/restrictions-for-unauthenticated-rpc-clients-the-group-policy-that-punches-your-domain-in-the-face.asp
Any help will be greatly appreciate.

Site to Site VPN connection for two Domain Controllers
I need to set up a site to site vpn connection using 2 pix 500 series firewalls to connect 2 domain controllers. Once the site to site vpn is established, do the servers automatically see each other for replication?
Thanx.My Active Directory guy has taken a good look at a small site-to-site VPN setup that I'm having a BIG problem with, and his answer is "They're supposed to." He said that as long as DC#2 (in the remote office) has the ability to resolve DNS for DC#1 (in the primary office) then the two should automatically replicate.
I have a two-office IPSec site-to-site tunnel between two 831's running 12.4.11T (soon to be upgraded to the latest 11T or even 15T1). XP SP2 machines in the remote office have full visibility back to the shares in the central office, and pings and nmap scans work perfectly in either direction, but my newly-added DC#2 in the remote office isn't replicating back to DC#1 (the original DC for the environment). I ran a full nmap scan from the central office against DC#2, and can see all of the expected ports/services open (e.g. 389(LDAP), 445 (msds), 135, 137, 3389, etc) but I can't view shares on DC#2 (or any other PC in the remote office) from the central office. Again, DC#2 and remote office PCs have no problem seeing shares back at headquarters.
Sorry for not being more helpful - hopefully someone out there can shed more light on the topic. If not, I'm going to call it into TAC and I'll let you know.
But again, from an Active Directory perspective this should 'just work' so it seems that either the IPSec tunnel or perhaps the "ip inspect" IOS CBAC firewalls are getting in the way. -
I need to find domain controllers that have been removed but never demoted.
Here's the story...
I came on an Active Directory administrator for an organization which has 600+ domain controllers, most running Server 2003, but I have some Server 2008R2. Throughout all this time the organization has had DCs that have stopped working, crashed or failed
for some reason and all the IT department has done is created another domain controller name it the same thing with an (A), (B) appended to the name and then never removed any of the failed controllers from the directory.
Thing is this has been going on for quite some time, don’t know for sure how long as I am still trying to clean up DNS replication problems and have been having to go around and reset machine passwords for the forest. What I need to be able to do is to script
something that will return all the failed DCs so that I can go into the directory and use NTDUTIL to clean the machines. I don’t want to go into the directory and remove a machine that’s still out there. No one in the organization has a list or record of failed
machines.
You can see this may be a gargantuan task, but I need to be able to make it easier on
myself by finding the machines first and cleaning out DNS, cleaning the DCs out of the “Sites” and cleaning them out of the directory.
Appreciate any help I can get…Hi,
Thanks for posting in the forum.
Regarding your question, maybe we should remove these orphaned DC from AD, please try to refer to the following articles to perform the cleanup task.

Blue Screen on Domain controllers after Updates
After patching our Domain controllers (virtual on ESXi 5.5 U2) recently we started getting Blue screens and reboots. Other changes in our environment around this time include enabling vshield drivers and scanning with Trend Micro. I have removed patches
from April but cannot remove Patch KB3020370 - there is no uninstall button. The error still persists, I have removed the Vshield driver and am waiting to see if the issue reoccurs. Can anyone assist in interpreting the details below? Also is it possible to
remove the patch KB3020370? This only appeart to affect Domain Controllers, regular servers appear unaffected.
Thanks

Followup: MachineOwnerHi,
Dump file displays:
BugCheck 7F, {8, 80050031, 406f8, fffff800018d4e14} and Probably caused by : ntkrnlmp.exe ( nt!KiDoubleFaultAbort+b2 ).
Bug check 0x7F typically occurs after you install a faulty or mismatched hardware (especially memory) or if installed hardware fails.
A double fault can occur when the kernel stack overflows. This overflow occurs if multiple drivers are attached to the same stack. For example, if two file system filter drivers are attached to the same stack and then the file system recurses back in, the stack
overflows.
You may reference the link below for detailed resolution about this problem:

Besides, you may try to restore the server to the state before installing these Windows Update.
Best Regards,
Eve Wang
