This should not be changed so that the domain owner can correct mistakes such as an improper access control list (ACL) or recovery of lost sub-trees when administrators are terminated. Note: Even though the OU owner is delegated control over a sub-tree of objects, the domain owner retains full control over all sub-trees.

30 client-pc’s (and 6 Servers, one of them the W2K3-Exchange 2003, another SQL2005 on W2K8 R2), at location2 (production, stock. At location1 (Headquarter, Financing, Sales) I have app. Is there a way to Change. Actually I didn’t set up anything in AD or DNS with “newcompanyname. Both sides are connected through VPN (site-to-site). At, mail-gw in DMZ is mail. I’ll try to explain:
The official external domain is company. The internal domain is also company. May I ask you a question about my situation at a customer. At, the Netbios-name is company (same as real name of the company). Hi Mark,
very, very interesting articles. At (AD) and company (Netbios) to newcompanyname. All users in AD identify through netbios-name “companyuser1” (on both sites)
Now I have the situation, that the company changed the name to newcompanyname. At is already set up and works with additional address-space in Exchange (additional default-mailaddresses [email protected] Thanks in advance for your appreciated advice. What users there ask me:
Is it possible to change the names (AD, Netbios) from company. At parallel to existing and moving users/pc’s/servers to the new AD-/Netbios-Domainname. At (AD) and newcompany (Netbios). I have two locations, on each a domain-controller (W2K8 R2), FQDN of the Servers are location1. I don’t want to think about lot of work on setting up newcompanyname. ) I have app. All users authenticate the same way on both sites. 50 client-pc’s (and 7 servers, one of them W2K3-Terminalserver, another also SQL2005 on W2K8 R2). The internal Exchange-Server is a W2K3-server with Exchange 2003.

Successfully designing an Active Directory (AD) tree is no small feat. AD has many different components and concepts that can easily confuse and intimidate.

If you have Windows NT resource domains that are independently managed by separate IT groups, you can place the new OUs on the top tier, under the domain root. If a Windows NT MUD owner owned and managed the contents of the former resource domain, then the resource OU can be created as a sub-OU of the corresponding Account OU.

OpenStack Icehouse – Active Directory Integration – Behind ...

Because it is the simplest model to administer, you should strive for a single forest design for your organization. The highest-level container in Active Directory is the forest. However, a single forest deployment has several constraints and not every organization can chose this model. As a first step in the design process, the Active Directory architect and project manager must determine how many forests an organization requires.

I’ve seen big companies with 150k users using AD that’s still referencing old company they bought years ago, or companies that changed names and even though it doesn’t matter in the long run that you are using login (if you can’t use UPN) it’s still looks bad in front of management who doesn’t understand why it’s not trivial to change it.

For example, if your DNS root name were contoso. Add a prefix that is not currently in use to the registered DNS name to create a new subordinate name. This new branch of the namespace will be dedicated to Active Directory and Windows 2000 and can easily be integrated with the existing DNS implementation. Com, where the namespace concorp. Com then you should create an Active Directory forest root domain name such as concorp. The rules for selecting a prefix are listed in Table 9. Com is not already in use on the network.

Best Practice Active Directory Design for Managing Windows ...

In a site, a single bridgehead server is active per domain. If this condition exists and there are more than 20 site links from the hub site to branch sites, the hub site can be divided into multiple sites to provide additional bridgehead servers to handle the replication volume. This condition can occur in large hub-and-spoke deployments where most sites are branch sites that communicate with a centralized hub site. If the site has more than 20 site links, the bridgehead servers can become overloaded.

If you have an existing DNS namespace with existing reverse lookup zones, the existing DNS administrator can continue maintaining those zones. If you do not have an existing DNS namespace, you do not need to create reverse lookup zones in order to deploy Active Directory. Reverse lookup capability is not required for the proper operation of Active Directory.

If another organization later registers the same DNS domain name, or if your organization merges with, acquires, or is acquired by other company that uses the same DNS names then the two infrastructures can never interact with one another. Note: As a best practice use DNS names registered with an Internet authority in the Active Directory namespace. Only registered names are guaranteed to be globally unique.

On the other hand, if a client asks a server to give it a name that corresponds to a given IP address, it is asking the server to perform a reverse lookup. The answer is located in a reverse lookup zone. Computer IP addresses are stored in records called pointer (PTR) records.

During deployment, you distinguish users and groups who belong to the domain owner from regular users and groups. Regular users and groups will be moved to the appropriate Account OU. Domain owner users and groups will stay in the default Users container.
