Change domain trust for Forest trust

Hi
I have a forest A with 3 domains (1 (root),2,3) and i have a forest B with 2 domains (4 (root),5).
Presently, i have a domain trust between domain 2 and 5.
I need to change for a forest trust ? what is a best practice ?
1- Remove domain trust and create a forest trust?
2- Create a forest trust (waiting a few day) a remove a domain trust?
3- Create a forest trust and remove immediately a domain trust?
Do you have a link to explain that?
Thanks

Hi,
Which kind of domain trust have you created? Which kind of forest trust do you want to create?
A one-way forest trust allows all users in one forest to trust all domains in the other forest; a two-way forest trust forms a transitive trust relationship between
every domain in both forests.
Based on my understanding of forest trust, a forest trust is a transitive trust between a forest root domain and a second forest root domain. If you create a forest
trust between two root domains in forest A and forest B, it provides a one-way or two-way, transitive trust relationship between every domain in each forest.
In another word, all the domains in forest A and forest B would inherit the trust relationship from their root domains. Personally, you can just create a new forest trust and keep the existing domain trust.
In addition, please make sure that the forest function level is Windows Server 2003 or higher before you create a forest trust.
Best regards,
Susie

ISE 1.2 Authentication fails for 2nd AD domain with the forest trust relation

We are running cisco ISE 1.2, we have new AD domain with forest trust relation between both the new and the old. authentication to with the new domain fails.
Is there any requirements or configurations change needs to be done to make it success?

Use the license that is currently on your ISE. If your account has access to download the software, then you are good. The license will not change during the upgrade. If you are using ISE 1.2 Patch 8 or above, then you are using the same Base/Plus?Apex Licensing model.
If you are not yet on Patch 8, the you are using Base/Advanced and these will be converted during the upgrade.

Server 2012 R2 no longer able to query objects in a trusted domain over a Forest Trust using Selective Authentication

I have a scenario in which our enterprise activation servers exist in a domain that is in a separate forest than our offices. Currently all our domain controllers are 2008 R2 with domain and forest functional levels at 2008 R2. We have set
up two-way forest trusts with our office domains using selective authentication. We then give the domain controllers from our licensing domain the "Allowed to Authenticate" right to the domain controllers in the office domain. On the
server 2008 R2 domain controllers in the office domain, we can browse to the appropriate objects in the licensing domain after being presented with an authentication window that allows us to enter credentials for the licensing domain. However, after
installing a 2012 R2 domain controller in an office domain, we can not use the 2012 domain controller to browse to the objects in the licensing domain. It never asks for credentials for the licensing domain when we specify the objects we want to add
from the licensing domain. I simply states that the object can not be found. When I look at the domain controller in the licensing domain, I see that the domain controller in the office domain is attempting to pass the credentials of the user that
is logged on and this is failing since this user has no rights in the licensing domain. I can still use a 2008 R2 domain controller in the office domain to add the rights and it works like it always has. Can somebody tell me why this is happening
and how to correct it?

Hi,
Based on my research, this is a known issue in Windows Server 2012 R2.
According to the article below: “The Selective Authentication feature of selective trusts is
not functional. Access to resources enabled by “Allowed to Authenticate” will fail. There is no workaround at this time”.

Migrating from 2003 domain/forest level to 2008R2 with all DC's at 2008R2 and 2 other Domain External and Forest Trusts

Is there anything that needs to be done or considered when migrating from 2003 domain/forest level to 2008R2 with all DC's at 2008R2 with 2 other 2003 separate Domain incoming
and outgoing Trusts, one Trust that is a Forest Trust and the other is an External Trust? Is there any chance or risks that doing this upgrade will break either one of these Trust relationships? Some of the user accounts with SID history have been migrated
from both Domain Trusts to our domain. Any chance that this upgrade will break these relationships for users that are using SID history for access to folders and files in their old Domains? If so what can be done to protect these trusts and SID history, prior
to moving the Domain to 2008R2

Hi,
Based on my knowledge,
the Upgrade of the function level do not affect the trust relationship.
Besides, before you upgrade the Functional Level,
verify that all DCs in the domain are, at a minimum, at the OS version to which you will raise the functional level.
Once the Functional Level has been upgraded, new DCs on running on downlevel versions of Windows Server cannot be added to the domain or forest.
For more information about function level, we can refer to following links:

Domain Upgrade & Cross Forest Trusts

Hi,
I manage a single windows 2003 Forest with a single domain (AD Level Windows 2003 R2). I'm preparing to upgrade the domain to Windows 2008 R2 but before I do I'm hoping someone can advise if this will impact on a number of cross forest trusts I have
with related organisations.
The trusts are a mix of 1 way and 2 way non transitive domain level trusts.
My query is, will I need to recreate these trusts after and "adprep /forestprep" or "adprep/domainprep" (getting resources on the opposing side lined up to do create\recreate trusts is a big job so I'm hoping the impact with be zero).
Thanks in advance
Paul

> if this will impact on a number of cross forest trusts
No, it will not.

Changing Domain Controller for Exchange 2013

Folks
I have an Exchange 2013 running on Server 2012.
Old DC on Server 2008.
I want to decommission the 2008 server. I have build a 2012 DC and for the life of can not work out how to change the DC that my exchange box uses????
Using Set-ADServerSettings cmdlet only seems to change the server for that current session?? reboot and back to the old DC...
When I use the Se-ExchangeServer cmdlet, I get domain controller cant be found. I have set the execution policy on the dc to unrestricted and still Domain controlleer cant be found..
New dc is a GC..
Any ideas would be good.
-graham

First, the behavior observed for the cmdlet Set-ADServerSettings is normal. The values for the domain controllers
designated are " per session". For example:
The PreferredServer parameter
specifies the FQDN of the domain controller to be used for this session.
http://technet.microsoft.com/en-us/library/dd298063(v=exchg.150).aspx
+++
What parameters, exactly, did you use for Set-ExchangeServer? What was the entire command?
If the domain controller(s) were found for "Set-ADServerSettings"
and... if Exchange is functioning OK in general, the domain controllers should be accessible.
+++
Are you in a position where you could shut down the older server (during off hours for example) and see if Exchange can
find - and use - the newer DC?
Will you only have one DC after decommission of the old one?
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.

Domain trust for external exchange domain

Ok so I have inherited two domains, one domain runs activedirectory services that all of the workstations are joined to (domainA), thesecond domain hosts exchange (domainB).After signing in on a computer in domainA we have to authenticateoutlook with domainB to get email.The end result, I would like is to be able to authenticatewith domainA for email but have it load the profile as if it was domainB.

I've messed around withAuthenticate as permissions on domainB but that doesnt seemto work correctly.

Here is the complete smsts.log: http://1drv.ms/1pwTEBf
To explain the Problem in Detail:
The SCCM Primary Site Server and the Clients are in different trusted (bidirectional) forests!
Everythings working fine in this Scenario, I can install SCCM Agent on the Clients with Manual ccmsetup and with Client Push Installation. Additionally i can deploy Software Updates and so on... only OSD is crashing in the releaserequest step.
During my Tasksequence new Clients are joined to Domain A while SCCM Primary Site Server is installed in Domain B
If I change my TS and let the Clients also join Domain B everything works without any Problems and the Tasksequence finish without any Errors.
My Problem must be related to the different Domains and the forest trust.
My Setup:
MP published to DNS in both domains
Schema Extended in both domains
System Management Container published and verified in both domains
ccmsetup Parameters in TS: ccmsetup SMSMP=sccm.domain.b FSP=sccm.domain.b DNSSUFFIX=Domain.b
Network Access account configured with Domain B account
Domain Join account has create Computer rights on the OU in Domain A (Domain join is successful)
DNs conditional forwarders configured in both Domains and DNS resolutin is working in both directions
Any suggestions?
Many thanks.
regards,
Christian

Hi Christian,
So do you actual get an error message in your TS or is it just failing to join Domain B? (Could be both if the machines fails to join the domain).
Can you review netsetup.log on the machines after the issue and see what error message you might be getting during the domain join process?
Also, if it a domain join issue, can you try manually joining to domain B using the same service account?

AD authentication for domain in another forest- XI R2

Situation:
- Windows 2003
- BOXI R2 (tomcat)
- 2 domains (in different forest)
- trust between the two domains
We have succesfully installed the AD-authentication plugin for domain1.
To work around for domain2, we've added users from domain2 inside a group of domain1, but these users are not shown inside the CMC when we import the AD-group.
Can we use the LDAP plugin for the domain2? What should be the procedure?
If found a similar question on this forum from one month ago, where they were talking about BO3 SP1, which will support multiple forest. But not really a solution the could help me out now.
Please advise
Thanks in advance!
Quinten

In XIR2 we cannot map in groups that contain users from 2 different forests. To work around this we could use LDAP to AD, but there are a few limitations.
If you want to upgrade the version that should contain this will hopefully be out by the end of this month XI 3.1 or XI 3.0 integrated SP1.
There should be some notes on using LDAP to AD in the SMP as well as it's documented in the [XI 3.0 Admin Guide|http://help.sap.com/businessobject/product_guides/boexir3/en/xi3_bip_admin_en.pdf]

Cisco ISE and forest trusts vs domain trusts

Hi All,
Is there any issues with forest trusts with Cisco ISE ?
I have a customer that had external trusts and ISE was working ok for PEAP MSChapv2 user auth across domains.
They recently removed external trusts and changed to forest trusts. Now auth doesn't work. Initial error was authc ok, authz fail.
I can search and get lists of AD groups ok for the remote domain.
Using the attribute tab, I can't get attributes for users in remote domain. I'm thinking since I can't see the memberof attribute, none of my authz pollicies will work.
I have done "leave" and "join" domain again.
In my lab, I have forest trusts and it actually works ok. A previous poster talked about kerberos issues across forest trusts ?
Cheers
Peter.

Two-way forest trust between two (single domain) forests with multiple identical user ID's

Domain and forest levels - Windows 2003 (they both have one 2008 R2 DC)
We need to create a two-way forest trust between two separate single-domain forests. The problem is that these two forests already access each others resources through a S2S. Users have the same login names and passwords on both forests/domains. Now, we
are combining their infrastructures and need to set up a trust. From what I'm reading, you can't create forest trusts if you have the same SIDs, user ID's, or computer name in each of the forests.
I'm looking into AD migration tool to copy the userSIDs (SID history?) between forest/domain, deleting the user ID's in the domain we migrated from, and then setting up the trust, but I'm leery about doing it this way as there is no easy 'recovery' should
something go wrong.
Any suggestions for the easiest way to setup this forest trust?

Hi,
To eliminate your worries, two user accounts have the same user name doesn’t mean that they have the same SID. Moreover, the user’s SID remains the same even after it has been renamed.
The SID for domain account/group consists of a
Domain Identifier and a Relative Identifier. Domain Identifier is unique in every domain within a forest, and a Relative Identifier is unique within domain. It is unlikely that two user accounts with or without the same account
name from two forests have the same SID.
The Technet article you mentioned is talking about duplicate SIDs instead of “duplicate computer name or user account”, I will submit a change request to Microsoft about this.
If there are duplicate SIDs when you create forest trust, you need to delete one of them as the article guides.
Here are some related articles below for your references:

Forest trust unable to find Active Directory Domain Controller

I have two domains with a two-way forest trust. We'll call them ForestA and ForestB. They're on seperate subnets. ForestA's DCs are in one physical location. ForestB's DCs are in two locations, one of which is shared with A.
I'm unable to route traffic directly from the remote DC in ForestB to the subnet ForestA is on, so I created a new DC in ForestA that sits on the subnet ForestB uses (basically, I can't route between subnets via the wireless bridge between locations, but
can within the same location).
I found this: http://www.neomagick.net/zen/2008/11/30/using-dns-to-force-a-domain-trust-through-a-specific-domain-controller-dc/
I followed the instructions to set the new DC in forest A to be the only one the remote DC in forest B was aware of.
Nslookup ForestA.com resolves correctly to this DC, but I'm unable to validate the trust relationship, getting the error:
"Windows cannot find an Active Directory Domain Controller for the ForestA.com domain. Verify that an AD DC is available and then try again."
I'd appreciate any help.

In the event viewer, have you found any event id's that corrospond with this error? Have you ensured all ports required are open? Windows firewall is correctly setup? NIC is properly configured?
Statement below taken from: http://technet.microsoft.com/en-us/library/cc961803.aspx
If you receive the following error, ERROR_NO_LOGON_SERVERS while using the Nltest tool to query the secure channel, this is usually indicative of the inability to find a domain controller for that domain. Run nltest /dsgetdc: < DomainName > : to verify
whether you can locate a domain controller. If you are unable to find a domain controller examine DNS registrations and network connectivity.

Single Label Domain - Corss Forest trust issue!

Hello There
We have a single label root domain ex: "abc" trying to establish the external trust with the other forest's root domain which is FQDN ex: xyz.com. The trust seems to be working fine from abc to xyz.com however the trust from xyz.com to abc is an
issue.
We are not able to resolve/ping domain abc from xyz.com DC. We are able to ping DCs in abc from xyz.com.
On xyz.com DNS forwarder are pointing to abc DNS server and WINS has been configured to route to abc WINS. Everytime when I ping abc from xyz.com DC its pointing to some unknown IP.
on the xyz.com DC tried setting up the registry key AllowSingleLabelDnsDomain, updated the LMHOSTS and host file with abc domain but still unable to resolve the single label domain. We could not suspect that its an issue with the network as we are able to
ping abc domain DCs from xyz.com
Thanks in advance.

Hi,
It’s not recommended to use LMHOSTS file. Instead, we can use conditional forwarders or secondary DNS zones for DNS resolution between the
two forests. Besides, we need to open required ports for building inter-forest trust.
Regarding how to configure name resolution between two forests, the following article can be referred to for more information.

Move domain to another forest (forest trust)

Hello
I have a forest with many domains , and other forest with a domain. They include a trust set up and working . I would like to have only one forest, but it would need to move that single domain in additional forest, and would like to know if it is possible then
moving a domain from one forest to another forest in forest trust ?
Thanks also suggestions stop solve my problem

You're asking to move the domain itself? No, you can't move the domain. You can create a new domain in the forest you want to consolidate to, and then migrate users and groups to that forest. You'll have to migrate workstations and users and repoint
applications as well, if needed. And then, you're not really moving them, you are creating new ones and copying properties of those objects. You mentioned a forest trust but all the forest trust allows you to do is to assign/use permissions from one forest
in another. People speak of moving objects but like I said, for users and groups you're simply creating new ones with the same names, and copying properties over. Computers/servers are joined to the new domain, but it's a new computer account, not one that
gets moved over.
You'll need a migration tool to do this smoothly. As Malek mentioned ADMT, yes this is one tool that can do this. It's not necessarily the best or easiest tool, but it's free from Microsoft. There are also other third party tools such as Dell/Quest
Migration Manager for AD and BinaryTree also has similar tool (there are others out there too). Those two latter tools have the ability to add permissions (ACL entries) to new domain objects, based on the old ACLs from the source domain. This can be a huge
help for servers and workstations (allows the users to continue to use their same profile after their computer is migrated, and they are using their new user account. Otherwise Windows would just create a new profile when the user logged in with his/her new
domain account.
Depending on the size of the domain you want to move (how many objects), this could be a pretty big project. There's a lot going on in a migration, and based on your question, I'd recommend finding help with it if you can. There are a number of companies
and consultants who specialize in AD migrations, even some consultation for planning could help tremendously.

What difference between a domain trust and a forest trust?

What difference between a domain trust and a forest trust?

Greetings!
The answer is right on the question! :)
I think it is best to distinguish properly between forest and domain. This article is a good one:
What Are Domains and Forests?
But in a nutshell, a forest trust is mostly used between two organizations, Suppose company A has a unique forest and company B has another unique forest as well, when they are merged they can simply create a forest trust between each other, This trust can
be one-way or two-way depending on your needs.
Domain trusts are between a single instance (domain) of a forest to another instance (domain) of another forest. It is worth mentioning that trust can be transitive as well.
What Are Domain and Forest Trusts?
I hope you got the answer.
