I can set up the incoming side of the trust relationship on domain "a" so that it trusts domain "b". This is strange. Because if the trust is incoming. Hellow Experts, I had 3 windows DCs that had a trust relationship with NT 4 PDC and Can I just do domain trust relationship? or forest?. Solution: Shouldn't matter if the dc is or - the trust should still work the.

Trust relationships allow companies to merge domain user accounts fast and efficiently, as well as have different databases for domain users even if they work for the same company. This option is essential for a Windows enterprise environment, so the verification of the trusts that are established is important for the audit and security perspective.

What is a Trust A trust is a logical relationship between two Windows domains. We will focus on the main Windows domain being an Active Directory domain in our discussion here, as this is what most companies have.

In order to understand how the Active Directory domain utilizes the trust, we must first get a core understanding of how the domain is structured and what the domain is used for. The main purpose of a Windows Active Directory domain is to authenticate user accounts and computer accounts. The domain is responsible for storing the computer and user accounts in a database. For Active Directory this is known as the Active Directory database.

The domain will also have a domain name associated with it. The domain name can be any DNS approved domain name, such as microsoft.

For a simple company with a single Active Directory domain, such as braincore. When a user logs on, there is only one choice for the user to log on, which is braincore. Both companies have over 10, user accounts, so the merging of the two companies into one domain is not efficient. Also, both company names must be maintained for branding purposes. In this case, a trust can be established between the two domains. This will allow users in either domain or location to log on to either domain, depending on where their user account is stored.

So, if Ralph is visiting the TechSales office, logging on to a computer that is associated to the TechSales domain, he can still authenticate back to the BrainCore domain, since there is a trust. What Trust Types Exist There are a few types of trusts that you might see when you audit or when you are establishing trusts in Active Directory.

These are independent of one another and are established without combining options. Internal trust - These are trusts established between Active Directory domains that are in the same Active Directory forest. These trusts can be between parent-child domains or between parent top level domains, domains starting new trees in the forest.

External trust to Windows domain - These are trusts that go outside of the Active Directory forest. These realms are what Unix use instead of Active Directory.

Auditing Windows Active Directory Trust Relationships

In essence, they are the same type of trust as compared to an external trust to a Windows domain. Cross-link trust - These trusts are internal to the Active Directory forest.

The concept is that a cross-link trust bypasses the traversal up the Active Directory tree, then down the Active Directory tree for domains that are multiple internal trusts away.

These trusts are created for efficiency of authentication within the forest when users are accessing resources in a domain that is not near where the user is located. Forest trust - These trusts were introduced with Windows Server domains. They provide a top level trust between two Active Directory forests. The goal is that all domains in both forests will be trusted, instead of having to create a trust between every domain to every other domain in the other forest.

If the copy of the computer account password that is stored within the member server gets out of sync with the password copy that is stored on the domain controller then the trust relationship will be broken as a result. So how can you fix this error? Unfortunately, the simplest fix isn't always the best option.

The easy fix is to blow away the computer account within the Active Directory Users and Computers console and then rejoin the computer to the domain.

Doing so reestablishes the broken-trust relationship. This approach works really well for workstations, but it can do more harm than good if you try it on a member server. 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.

Select the Reset Account command from the shortcut menu, as shown in Figure 2.
