trust relationship between different domains in the internet

Question What do I need to do in order to manage Client Computers in a foreign Windows Domain which doesn't have a Trust Relationship set up with the. This holds true even when trust relationships are involved. One of the primary differences between Windows NT style domains and Active I don't actually own the Internet domain name, but it doesn't matter. After the restoration, all of the other servers in the domain displayed an error This error message stated that the trust relationship between the.

In Windows NT, there was really no organizational structure for domains.

Networking Basics: Part 6 - Windows Domain

Each domain was completely independent of any other domain. In an Active Directory environment, the primary organizational structure is known as a forest. A forest can contain multiple domain trees. The best way that I can think of to compare a domain tree is to compare it to a family tree.

A family tree consists of great grandparents, grandparents, parents, children, etc. Each member of a family tree has some relation to the members above and below them.

The same technique is used internally in an Active Directory environment. Think about it for a moment. If this were an Internet domain, it would not be a top level domain, because. In spite of this minor difference, the same basic principle holds true. I could easily create a child domain by creating another domain name that encompasses production.

You can even create grandchild domains.

An example of a grandchild domain of production. Earlier I mentioned that an Active Directory forest can contain domain trees. You are not limited to creating a single domain tree. In fact, my own network uses two domain trees; production.

This domain contains my mail server and some file servers. The reason for this has to do with the way that some applications use the Active Directory. Take Exchange Server, for example. Exchange Server stores messages in a mailbox database residing on a mailbox server.

However, this is the only significant data that is stored locally on Exchange Server. All of the Exchange Server configuration data is stored within the Active Directory. In fact, it is possible to completely rebuild a failed Exchange Server from scratch aside from the mailbox database simply by making use of the configuration data that is stored in the Active Directory. The reason why I mention this particular example is that the Exchange Server configuration data is stored within the computer object for that server.

So with that in mind, imagine that a trust relationship was accidentally broken and you decided to fix the problem by deleting the Exchange Server's computer account and rejoining the computer to the domain. By doing so, you would lose all of the configuration information for that server.

Worse yet, there would still be orphaned references to the computer account scattered elsewhere in the Active Directory you can see these references by using the ADSIEdit tool. In other words, getting rid of a computer account can cause some pretty serious problems for your applications. A better approach is to simply reset the computer account. Right click on the computer that you are having trouble with. Selective Authentication Restricts access over an external Authentication setting must be manually enabled.

Transitive trusts Shortcut trust. A transitive trust between domains in the same domain tree or forest that is used to shorten the trust path in a large and complex domain tree or forest. A transitive trust between one forest root domain and another forest root domain. Non-transitive trusts External trust.

How to create an external trust between two seperate domains/forests

You have to fulfill few requirements before you can activate external trust. Both domain controller must ping each other by IP address. If both domain controllers are placed in different subnet then proper routing is required. If there is a firewall between domain controllers then proper firewall rules should be in place allowing LDAP, DNS and resources port to be accessible from both sites.

Forest and domain functional level must be Windows Server or later version. Resolve IP without any delay or timed out ping. Repeat the step to add But there is no harm creating a forward lookup zone in both sides as both forests are going to trust each other once trust is activated.
