Global catalog problem

hello everyone
in our company we are upgrading our DCs to server 2012R2 we have one Dc 2008R2 we installed another DC 2012R2 and make it GC from sites and services the problem appeared when I demoted the 2008 server I noticed that nobody in the company is able to log to
the domain I realized that even the global catalog check mark is checked the server is not global catalog when I connect through ldap I see isglobalcatalogready : false I tried many solution to make it global catalaog but no success my solution was to shut
down this server and restore the 2008 server from a previous backup now all the users can log to the domain but I only have one DC I tried to add another 2012R2 Dc but DCPromo fails on the prerequisite "check verification of outbound replication
failed error reading the ntds settings on replication source controller" I installed another server 2008R2 server since there is no prerequisite check but the same problem occured the new DC is marked as GC but it's not GC I checked port 3268 I ran dcidag
and this is the result

In addition, I just wanted to point out that the error you are receiving below, can be indicative of some sort of firewall block. Antivirus apps can do this, too, with their network protection features.
"check verification of outbound replication failed error reading the ntds settings on replication source controller"
Do you have an AV on the machine, or the Windows firewall, or a third party firewall enabled?
Run PortQRY to see if there are any ports blocked.
PortQry GUI -
Run the "Domains & Trusts" option between DCs, or between DCs and any machine (other servers you want to promote, or even from a client machine), that you want to test if there are any blocked AD ports. Post only errors with "NOTLISTENING," 0x00000001,
and 0x00000002. You can ignore UDP 389 and UDP 88 messages. If you see TCP 42 errors, that just means WINS is not running on the target server.
PortQryUI - GUI - Version 2.0 8/2/2004
http://www.microsoft.com/download/en/details.aspx?id=24009
Time issue?
A time skew between DCs that is beyond 5 minutes, can cause it, too. Are the clocks on the new server and the current DCs within 5 minutes? Is the PDC emulator configured to sync time to an outside or to a local, reliable source?

http://blogs.msmvps.com/acefekay/2014/04/26/configuring-the-windows-time-service/
And of course we are all assuming that the new machine is definitely only using a current DC as the only DNS address in its NIC.

Cisco ISE with AD Problem: "Could not read groups data: Global catalog not found"

Hi all,
When I make the ActiveDirectory integration with Cisco ISE, I have complete with this integration. but when I try to read the Groups from Active Directory, ISE shows the message "Could not read groups data: Global catalog not found".
My Domain has multiple sites and subnets, each contains GC for local logon. I have set ISE to the correct site and subnet. Forward and Reverse DNS are working with no error.
Does anyone get this problem, please help.
I have check into the ISE CLI Reference Guide 1.1.x
You are about to configure Active Directory settings.
Are you sure you want to proceed? y/n [n]: y
Parameter Name: dns.servers
Parameter Value: 10.77.122.135
Active Directory internal setting modification should only be performed if approved by ISE
support. Please confirm this change has been approved y/n [n]: y
What shoud I set in the Parameter Name ? dns.servers or my dns hostname ?
Please suggest for this too.
Thanks and Regards,
Pongsatorn M.

Hi Pongsatorn,
Thanks for the reply!
I've attached the results of the ISE detailed AD test. As you can see, there is a fair number of domain controllers in the AD forest.
It seems everything works correctly until it gets to testing the AD connectivity on port 3268. Then I get this:
Testing Active Directory connectivity:
    Global Catalog: pdascdc02.xyz.com
      gc:       3268/tcp - refused
Testing Active Directory connectivity:
    Global Catalog: pdascdc02.xyz.com
      gc:       3268/tcp - refused
For some reason, the request to the controllers on port 3268 is being refused.
Any thoughts you might have are greatly appreciated.
Cheers,
Greg

A Global Catalog Server could not be located - All GC's are down SBS 2011

I have been searching through these forums and manage to find similar errors but am struggling to find an answer that applies to this me.
I seem to be having a number of issues with our SBS. I believe this was originally domain was previously on a SBS 2003 box before being moved to this SBS 2011 box last year, it has been running fine until yesterday. I cant see anything that has changed then
though.
Everything seems to point to DNS although I am struggling to pinpoint the actual cause. The most worrying is when I try to open something on the SBS such as AD sites and services.
the error is

I found a few people who have had similar issues that was caused by the "netlogon" service being paused or stopped but in my case it is set to automatically start and is running.
I have also posted this to serverfault (cant post links yet serverfault.com/questions/522691/a-global-catalog-server-could-not-be-located-all-gcs-are-down) added as there may be info there that may help.
Thanks for taking the time to read this, hopefully someone out there has come across this before or can offer something in regards to the next steps I should take.

Some troubleshooting ideas:
0. Check if the DCs can resolve each other using their DNSHostName. If not, this indicates some DNS misconfiguration
-- you need to fix that first.
1. Check if the both the DCs are pointing to the same DNS server (or DNS servers that are replica of each
other). Run: "ipconfig /all" and check its output. If not, correct the DNS client settings and run dcdiag after sometime.
2. Check if dynamic updates are "turned on" on the DNS server.
3. Try re-registering the DCs SRV records by either restarting netlogon service or by running the following
command:
nltest.exe /dsregdns

Global Catalog and Searching Child Domains

Hi Everyone,
I'm attempting to sync events from a parent domain and I want to include all child domains as well. The forest contains a parent domain with 2 child domains. In my adapter I have the following configuration specified:
Container: DC=parent,DC=company,DC=com
Search Filter: DC=parent,DC=company,DC=com
Search Child Domain: Checked
Global Catalog: DC1.parent.company.com (Domain Controller of the parent domain is configured as Global Catalog)
When I attempt to sync domains from the child domain I recieve the following error:
dn attribute not found in search result
Does anyone have insight into what might be occuring. I can query the gc and can retrieve the events with no problem from other tools but IDM seems to always have an error for these child domain events. All comments or suggestions welcome. Thanks

This is the actual error from the AS log if that helps:
2009-10-09T13:26:13.840-0500: com.waveset.util.WavesetException: Unable to find dn attribute for object returned from search.

Can't reach global catalog server.....that I am actively pinging....

Hello.
Background
I have a Window server 2008 r2 installation that I fell in on. I removed all roles and features. Renamed, and gave a new ip address
I ran DCpromo and installed AD and DNS. this server was to be the first in a new domain.
After successfully creating the domain, I added my workstation (laptop) to the domain successfully and logged on with a created domain administrator account.
I installed the remote administrator pack for windows 7 onto my workstation
Problem
I ran AD Users and Computers (from my workstation) and proceeded to create a user... only to be told:
"Windows cannot verify that the user name is unique because the following error occurred while contacting the global catalog: The server is not operational."
Troubleshooting steps taken so far:
I have ensured that my workstation and server times match (to the second)
I have ensure they are in the same time zone, date, etc.
I am actively pinging the domain controller from my workstation WHILE I attempt to create the user, so network connectivity is ruled out. they are in the same subdomain, there is no router in between. it is workstation > switch > switch > switch
> server
I checked sites and services, to find only 1 server listed for the sole domain, and it IS checked as the global catalog server
My workstation when added to the domain registered in DNS appropriately. As is the domain controller itself.
DCDIAG /fix reports no errors, everything passes
metadata.cleanup cannot be used because there are not other domains or sites, or servers listed beside the one I created.
Please help....Thank you.

Please use dcdiag /v and repadmin /showreps
to check the DCs health status and AD replication.

When exchange Domain Controller or Global Catalog servers?

I have a few questions want to get your help.
1,which situation exchange would contact with the Domain Controller, and which situation exchange would contact with the Global Catalog servers?what's the difference?
2,for the mailbox replication service, besides moving the mailbox ,and DAD relevant operations, which situation mailbox replication service also contact with Dc?
Please click the Mark as Answer button if a post solves your problem!

Hi,
About Question 1:
For Exchange, GC is mainly for Address Book lookups. Exchange server access to the global catalog for address information.
About DC, every domain controller contains the following three directory partitions.
1. Configuration: Contains the Configuration container, which stores configuration objects for the entire forest in cn=configuration,dc= forestRootDomain.
2. Schema: Contains the Schema container, which stores class and attribute definitions for all existing and possible Active Directory objects in cn=schema,cn=configuration,dc= forestRootDomain.
3. Domain: Contains a < domain > container, which stores users, computers, groups, and other objects for a specific domain.
For example, each Exchange Server object has the attribute Boolean messageTrackingEnabled. The Exchange server processes will turn on or off message tracking depending on the value of this attribute in the directory. This is an example of configuration data.
Configuration data is stored in the Configuration partition of Active Directory, and this partition is replicated to every DC in the Forest. Therefore Exchange can potentially go to any DC to access this information.
About Question 2:
The Mailbox Replication Service is responsible for moving mailboxes, importing and exporting .pst files, and restoring disabled and soft-deleted mailboxes. All these options need to contact with DC.
Best regards,
Belinda

Could not find any available Global Catalog in forest when running RemoteMailbox cmdlet

My current Exchange environment is a hybrid configuration of Office 365, Exchange 2013 hybrid, and Exchange 2007 on-premise.
I have a script responsible for enabling remote mailboxes and assigning O365 licenses to a list of users; essentially provisioning users an O365 mailbox. This script runs every hour through a defined scheduled task in the Task Scheduler.
The script is proven to work but will intermittently throw an error on some days: "Could not find any available Global Catalog in forest root.xyz.com"
Here are the nuances of the error when it does occur:
It will only throw the error when the script is run via scheduled task - the script will work fine if executed from the command line
The error occurs when "Enable-RemoteMailbox" or "Get-RemoteMailbox" is called.
The same error will occur with ANY script that calls "Enable-RemoteMailbox" or "Get-RemoteMailbox" and is ran via scheduled task - even when the RemoteMailbox cmdlet was the only line in the script
Here is the output and error when Get-RemoteMailbox -verbose is ran:
VERBOSE: [15:49:52.474 GMT] Get-RemoteMailbox : Active Directory session

What could be the cause of this intermittent error?
Thanks for any help

looks to me permission error as when you are running it via a schedule task is is not able to call exchange shell/ commands {confirm this} where as when you running this manually looks to me you open exchange shell, may be as admin also and then running
the script.
schedule task process is not able to get the permission..

How to replicate 'memberOf' attribute to global catalog server

Hi,
I am trying to replicate 'member of' attribute to global catalog server, to get the data from child domain where trust is enabled.
i did a little reserach and found that 'isMemberOfPartialAttributeSet' should be true to get it replicated to global catalog server.
in schema, i am trying set 'isMemberOfPartialAttributeSet' true for "is-member-of-DL" attribute and getting illegal modification.
is there any other way, where i can modify (or with help of Microsoft).
OS: windows 2003 R2 (SP2) - MSDN
Thanks!
Karthik
Thanks, Karthikeyan R

Hi Karthik,
Based on my tests, the right way to modify attributes that replicate to the Global Catalog is:
Open Active Directory schema snap-in.
Then locate the attribute which you wish to modify.
Right click on it, and select Properties.
Tick the check box “Replicate this attribute to the Global Catalog”.
Here is a screenshot for you:

OID and Active Directory(global catalog) synchronization issues

We have a large network with 7 domains within the AD forest.....The OID server profile
points to a single domain controller/gc in 1 of these 7 domains. It is able to synchronize when a change occured
from this domain but not the others in the forest by quering port 3268/GC. We reloaded
the bootstrap which reduced the "highest committed usn" last read attribute value in
OID....and the synch started working again with another domain but not consistently(a change in AD gets pulled into OID)...
It seems as if OID cannot read the highest committed usn value for all domains
within one forest by quering a single global catalog domain controller in one
domain....any ideas on best practice to have a consistent synch from OID to all
domains in AD?
Message was edited by:
marcvip

Each AD server in the Forest will maintain his own highestCommittedHSN. The AD GC should maintain a consistent HSN but knows and keeps all the AD servers in sync. So if the GC does not maintain a consistent HSN you should contact Microsoft as well (besides this forum :-)

Exchange Management Shell Cannot Find Global Catalog Servers

Hello,
I have a client with a single Exchange 2013 RU2 multi role server. Exchange works fine with no issues. However, when I open EMS and try to do anything (example get-mailbox) it returns the following error. It was working up until about a
week ago.
"Could not find any available Global Catalog in forest domain.com"
I haven't tried rebooting the server yet because Exchange is running fine, it's just PowerShell is jacked up. I have even tried Remote PowerShell from another server and same results. Has anyone ever seen this?
Thanks,
John

can you check what your nslookup returns you... are you able to connect to your DNS without any error.
the above error is generally towards network connectivity issues.
guess you have two lan cards on exchange. what is the DNS on both lan cards. i guess should b same.

Help, error connection Cisco Identity Services Engine with AD, global catalog port status error

Dear all,
I have Cisco Indentity Services Engine, that connected to Active Directory. When I test connection detailed,
the result is error, said:
Test Connection Results
This dialog shows the detailed logs for the operation for: idsv0018.
Status: FAILED: Global Catalog port status error.
Can anyone help?
I believe, because this error, I can't search group of AD, at Cisco ISE.
FYI: the connection from Cisco ISE to AD, joined with successful result.
Thanks,
Jerri

It's clears that when ISE tries to find the GC using the _gc._tcp. DNS query. It doesn't find that information on the Domain controller. The GC information is missing on the DC.
gc._tcp.DnsForestName
Allows a client to locate a Global Catalog (gc) server for this domain.

Global Catalog Server?

I am upgrading three domain controllers by replacing old '03 DCs with new '12 DCs. The set is a parent domain with two sub domains for child organizations. No users in the sub domains should be able to log into the other domains or see the GAL for the exchange servers in the other orgs. Each of the three has their own exchange server. The same IT team manages all three, so we want to have them in the same forest. (correct term?)Should any of the domain controllers be a Global Catalog server? That is an option when upgrading the DC server from '03 to '12."Servers running Microsoft Exchange Server rely on access to the global catalog for address information. Users use global catalog (GC) servers to access the global address list (GAL).Because a domain controller that acts as a global catalog server stores objects for all domains in the...
This topic first appeared in the Spiceworks Community

CFLDAP requires a domain controller to be specified. It can't
use find the root dsn of the domain and start from there.
The best workaround is to "know" every domain controller on
your domain. Then, run a very simple LDAP query using the first
domain controller. If an error occurs, then try the LDAP query with
the second domain controller. Keep this up until you run out of
domain controllers. If this happens, then you are in worse trouble
because your domain will start to fall apart.
Use CFTRY/CFCATCH to test for any LDAP errors when a domain
controller is not responding. You can even wrap this into a simple
CFLOOP that loops over a list of domain controllers.
All it has to do is return a simple query that should take
very little time to process. All you are doing is testing to make
the sure domain controller is responding.
