I am getting 5719 errors on a DC.
This computer was not able to set up a secure session with a domain controller in domain LOL due to the following:
There are currently no logon servers available to service the logon request.
The domain they are refering to was forcibly deleted (no DCs were available to dcpromo/demote). I did it with NTDSUTIL metadata cleanup.
Also went into DNS and removed all references. I must have missed something. Any ideas where?
I have 4 ( A, B, C, D) sites, with 5 Domain controller. Domain name: India.local
mentioned below Network and Domain Controller and IP address.
Site A- Network / Subnet - 192.168.2.x, 3.x, 4.x, 5.x - (DC1- 192.168.5.10, DC2-192.168.5.11)
Site B- Network / Subnet - 192.168.10.x, 11.x (DC3-192.168.10.10)
Site C- Network / Subnet - 192.168.12.x, 13.x,(DC4-192.168.12.10)
Site D- Network / Subnet - 192.168.14.x, 15.x. (DC5-192.168.14.10)
Client : 192.168.3.15, 192.168.3.25
Client : 192.168.4.15, 192.168.5.25
Problem Description:
From Client system (192.168.3.15) When i am trying access AD user account to providing access, take long time get the user account details some time getting request time out. Looks like its using LDAP connection.
Finding:
When i am ping "india.local" from any Client system (3.x) resolving IP 192.168.12.10, after some time 192.168.14.10 ... (every 30 mins resolve different (DC) IP address) normally its should resolve either DC1- 192.168.5.10, DC2-192.168.5.11.
But no problem on client 192.168.4.15, 192.168.5.25
Could you please help this.

today i found this event on my server:
The File Replication Service has detected that the replica root path has changed from "c:\windows\sysvol\domain" to "c:\windows\sysvol\domain". If this is an intentional move then a file with the name NTFRS_CMD_FILE_MOVE_ROOT needs to be created under the new root path.
This was detected for the following replica set:
"DOMAIN SYSTEM VOLUME (SYSVOL SHARE)"
what should i do with this? Should i be worried?
I am familiar with some ADFS stuff and have onboarded and used a few sites but this is a totally new subject for me.
I have two Microsoft ADFS sites with urn Realms that I need to be in one web project. The first site is something like https://mydomain.com and the second site is https://sub.mydomain.com.
I know I can set one up as a subdomain and I have the hosts names set up correctly. But every time I try to go to any pages using the sub-domain it gives me 401 - Unauthorized: Access is denied due to invalid credentials error. Or the site will redirect to the realm I have in the web.config with passifRedirectEnabled
The page works perfectly fine when i dont add the subdomain to the hostnames and I have both sites on-boarded with corp ms stuff.
I have added both the urn values to the web.config file I am just not sure what else I need to add in the web.config file or config files to make this 401 access error go away and authentication still work.
I am sure there is similar articles to this I just am unable to find them. I would be very much thankful if someone could point me in the right direction
Hi,
We are creating a one way trust where DomA.com trusts DomB.com. To improve security, rather than allow full name resolution for all computers in DomA, we would like to create a forward lookup zone with manual host records for only those servers that are needed to create the trust and provide access to the resources DomB need.
For the trust creation, am I correct that a blank host record with IP of a domain controller is all that is needed? Thus DomA.com and DomB.com will resolve to DCs from the other domain.
Will this work or is a stub zone\conditional forwarding needed?
Many thanks

Hello,
I am trying to authenticate AD users on Cent-OS box.I have installed AD on my test machine. From Cent-OS, I can do ldapsearch on that.
However when I try to authenticate using users it gives error as user does not exist. I want to use LDAP for both authentication and retrieving metadata for users.
Is there any step by step instructions available to do this.
Hi All,
I want to change user logon name to AD and smtp email due to standardization on our company. When we change the login name what is the impact ? is it gonna change the user profiles on each workstation which they log on to ? for the smtp I know we can add a new one and make it primary but still keep the old one so sender still can send him an email. I really concern about the logon / samaccountname.
any ideas for this ? maybe giving a hint or step ? :)

Back Round:
ok, i have inherited a 3 site company... site meaning physical properties in one comapny. One site no dc just a shared file server which imnot worried about well call site 3. Site one and two have there own forest and DC's and connected via a cable internet VPN. My issue of course is to bring them into one as there is growing need to share files\folders etc... To start off with I cannot even create a trust between them, domain and forest level are 2008 (not r2) no reason just what i stopped at as they were in various flavors of domain and forest level when i got here. I do not push down any GP's (as of yet), only use the servers at this point for authentication for file and folder sharing and DHCP.
Question:
Why cant i trust the domains?
Will migrating with admt 3.2 (to a site) be my answer if so what happens to the dc's at site 2 when i move them to 1.
ideas?
I have done this multiple times with 2000, 2003 but dont seem to be able to find the solution to 2008.
When i run the trust it fails right after putting in the information of domains i go no further, it gives me no details just says "cannot finish"
Old server was a 2003 (64), running Exchange 2007 - PDC, no workstations connected. 100+ users accessing email using http/rpc. We had some other services on this server as well. very small 'webpage' for users to access over a vpn connection, and Symantec Corporate server as well. Things worked very well, no issues - unfortunately, the server was multihomed, which apparently caused some problems when we upgraded.
New server is a vm, on ESX - 2008r2, Exchange 2010. Everything came accross and worked ok, except we had a strange problem. the old server needs to be on to add users. Microsoft worked with us to resolve some issues with DNS and such, caused by the multihomed enviroment. Lots got resolved but this server was a production server, and we wanted to wait until we had replication setup before finishing off the job.
So, the other day, we finished off as per discussions with Microsoft, rebooted the new server, and poof. complete failure. Eventually reverted back to the replica. The replica actually works without the old server, but there are issues - often when you open Active Directory users and groups, it gives you an error.
Naming information cannot be located because:
the specified domain either does not exist or could not be contacted. contact your system administrator to verify that yoru domain is properly configured and is currently online.
If you play arround you can get this working. Because the server is working, we run replicas at night, and try and correct the replicas, if it fails we revert back to the original.
Replicas - Vconverter does a poor job of 'replicating' and we have to redo the network settings every time, and setup Routing and Remote Access. After we get that working, we do some Metadata cleanup tasks and such, as per various kb articles. We leave Exchange services off while we correct Directory Services. There are quite a few reoccurrent problems in DCDIAG - sample errors;
DsGetDcName (NewServer) call failed. Error 1355 The location could not find the server.
.................NewServer faield test Advertising
There are warning or eror events within the last 24 hrs after the SYSVOL has been shared. Failing SYSVOL replication problems may cause Group Policy problems.

the security of this directory server can be signifantly enhanced by configuring the server to reject SASL.....

Hello all!
Thank you for looking at my question. As the title suggests we are rolling out a new software that is hosted offsite. And requires an LDAP connection to to our Active Directory store for user authentication and content management via security groups.
Of course our domain controllers are not accessible from the web. However, we do have a DMZ box that is able to communicate with the domain controller over LDAPS. This was configured for an unrelated project, whose software was installed on the DMZ box.
What I think I need is what I will call a "LDAP Proxy" that allows for LDAP(S) queries to be ran against the DMZ box which is then in turn actually querying the real domain controller. Can this be Done with AD LDS? If so, can it be done without
"mirroring" or Syncing the user accounts between AD DS and the LDS instance? I would prefer the service account to be the only account with the ability to run queries against the DMZ box. As that is all this software needs. It uses this "service"
account to lookup users to determine logins, and what content should be delivered to the users.
Of course I will layer on security by preventing any authentication request but those from the server that will be running the third party software.
Is there any recommendations for this type of setup? I would prefer to use microsoft products, and would prefer to avoid an RODC in the DMZ.
Thank you all for your support!
We recently migrated from our two Server 2008 DCs to Server 2008 R2 DCs. I noticed that the DC that holds all FSMO roles (DC1) shows the following messages in Event Log:
The Security System detected an authentication error for the server DNS/DC2.domain.local. The failure code from authentication protocol Kerberos was "An attempt was made to logon, but the netlogon service was not started.

They are warning messages and all services boot successfully. Are there any solutions for these warnings?
Thanks in advance,

I have an issue at a client site which I need to try to resolve. The client has a Server 2003 DC, which when we attempt to join a new computer to the domain, the join fails. The error (which I do not have in front of me, sorry) involves a problem with the Global Catalog. Due to other issues with the existing server, we are looking at removing and replacing the existing DC with a new DC.
My question is, how can we go about transferring the existing Domain information (users, GPOs, etc) to the new DC? If the existing DC were working correctly, this would be a trivial task, join the new system, promote it to a DC, let replication happen, transfer the various Domain roles, done.
I'm thinking that possibly the following might work, but I'd like to confirm:
Should this work? Or is there a simpler method?
Thank you,
Jason A.

Hello All I am currently working on migrating some Schema Attributes to our ADAM server and I had a request come through that has me a bit stump. We have a scenario where the application owner is requesting the following:
He wish us to propagate the Domino attribute to a different attribute on ADAM server like the following: Domino-->UID? Is this possible if not what can I do to make this happen?
Hello,
in Active Directory under the organizational Units there is a property "msExchRecipientValidatorCookies".
Does someone know what this property is used for ?
We want to use this property to store some additional data in the organizational unit.
Thanks for your help.

Guys,
whats the difference between the "set Scavenging for All Zones" and the enable auto scavenging of stale records in the advanced settings of dns?
Windows 2008 DCs
we have three sites site1;site2;site3 and site2 is down (all three sites can connect each other)
we have sitelink site1site2; site2site3 created and ntds connections automatically created for site2site3: but since site2 is not avaialbe and I need to ntds connections automatically created between site1 and site3
Should I delete the current site2site3 link and create link site1site3? will ntds connections automatically created between site1 and site3?
