How do I find the full PC name under WIn? - Microsoft Community.Computer Names
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. You cannot add a user name or an object name that only differs by a character with a diacritic mark. NetBIOS computer names can contain all alphanumeric characters except for the extended characters that are listed in Disallowed characters.
Names can contain a period, but names can't start with a period. Names can contain a period. But the name can't start with a period. Periods should not be used in Microsoft Windows or later versions of Windows. For more information, see Special characters. In Windows and later versions of Windows, computers that are members of an Active Directory domain can't have names that are composed completely of numbers.
This restriction is because of DNS restrictions. The 16th character is reserved to identify the functionality that is installed on the registered network device.
See Table of reserved words. It shouldn't be used with Active Directory forests. DNS names can contain only alphabetical characters A-Z , numeric characters , the minus sign - , and the period. Period characters are allowed only when they are used to delimit the components of domain style names. Other implementations of DNS don't support Unicode characters.
Avoid Unicode characters if queries will be passed to the servers that use non-Microsoft implementations of DNS. The underscore has a special role.
But newer DNS servers may also allow it anywhere in a name. Otherwise, import , export , and take control operations fail. You might however create host headers for a web site hosted on a computer and that is then subject to this recommendation.
Because some UTF-8 characters exceed one octet in length, you can't determine the size by counting the characters. For more information, see rfc NetBIOS domain names can contain all alphanumeric characters except for the extended characters that are listed in Disallowed characters.
Periods shouldn't be used in Active Directory domains. If you are upgrading a domain whose NetBIOS name contains a period, change the name by migrating the domain to a new domain structure.
The names of an upgraded domain can include a reserved word. However, trust relationships with other domains fail in this situation. There is no inherent problem with this, but there may be applications that filter the name and assume a DNS name when a period is found. When promoting a new domain, you get a warning that an underscore character might cause problems with some DNS servers.
But it still lets you create the domain. Single-label DNS names are names that don't contain a suffix, such as. For example, host is a single-label DNS name. Most Internet registrars don't allow the registration of single-label DNS names.
Generally, we recommend that you register DNS names for internal and external namespaces with an Internet registrar. For example, corp. Registering your DNS name with an Internet registrar may help prevent a name collision. A name collision may occur if another organization tries to register the same DNS name, or if your organization merges with another organization that uses the same DNS name. By default, Windows Server based domain members, Windows XP-based domain members, and Windows based domain members don't perform dynamic updates to single-label DNS zones.
For more information, see Deployment and operation of Active Directory domains that are configured by using single-label DNS names. Don't use top-level Internet domain names on the intranet, such as. If you use top-level Internet domain names on the intranet, computers on the intranet that are also connected to the Internet may experience resolution errors.
A disjointed namespace occurs when a computer's primary DNS suffix doesn't match the DNS domain of which it is a member. For example, a disjointed namespace occurs when a machine that has the DNS name of dc1. A Windows NT 4. The domain is renamed when the forest is at the Windows Server forest functional level. This domain controller is upgraded to Windows When this upgrade occurs, the DNS domain is renamed contoso. In the original release version of Windows , the upgrade routine clears the check box that links the primary DNS suffix of the domain controller to its DNS domain name.
Event IDs and occur on a Windows-based computer. Create a Disjoint Namespace. In Windows , the maximum number of domains in a forest is In Windows Server and later versions, the maximum number of domains at Forest Functional Level 2 is This restriction is a limitation of multivalued non-linked attributes in Windows Server So, choose an Internet DNS domain name that is short and easy to remember.
Short domain names make the computer names easy to remember. If the organization has an Internet presence, use names that are relative to the registered Internet DNS domain name. For example, if you have registered the Internet DNS domain name contoso. Don't use the name of an existing corporation or product as your domain name. You can run into a name collision later on. Avoid a generic name like maybe domain. Another company you merge with in a few years might follow the same thinking.
Don't use an acronym or an abbreviation as a domain name. Users may have difficulty recognizing the business unit that an acronym represents. Applications might be very RFC obedient and reject the name, and will not install or work in your domain. And you might experience problems with older DNS servers. Don't use the name of a business unit or of a division as a domain name. Business units and other divisions will change, and these domain names can be misleading or become obsolete.
Avoid extending the DNS domain name hierarchy more than five levels from the root domain. You can reduce administrative costs by limiting the extent of the domain name hierarchy. If you are deploying DNS in a private network, and you don't plan to create an external namespace, register the DNS domain name that you create for the internal domain.
Otherwise, you may find that the name is unavailable if you try to use it on the Internet, or if you connect to a network that is connected to the Internet.
We recommend that you use a valid DNS name when you create a new site name. Otherwise, your site will be available only where a Microsoft DNS server is used. All characters are allowed, even extended characters. Although Active Directory Users and Computers lets you name an OU with extended characters, we recommend that you use names that describe the purpose of the OU and that are short enough to easily manage.
When the OU at the domain root level has the same name as a future child domain, you might experience database problems. Consider a scenario where you delete an OU named marketing to create a child domain with the same name, for example, marketing.
The OU is deleted and during the tombstone lifetime of the OU you create a child domain that has the same name is created, deleted, and created again. In this scenario, a duplicate record name in the ESE database causes a phantom-phantom name collision when the child domain is re-created. This problem prevents the configuration container from replicating. Skip to main content.

Thanks for reading my article. Visit ZubairAlexander. All rights reserved. I find it amusing that you so strongly advise against using hyphens in a computer name, yet Microsoft automatically names Windows systems using a hyphen! What were they thinking?!

The Host Name is your computer name. Was this page helpful? Thanks for letting us know! Sorts nice in a network view, report, or spreadsheet though. Although you can successfully override the 15 character netbios limit, it just makes your server names more unwieldy.
The companies or remote sites are their own legal entity. So if one sells, I need to easily remove them from our AD as a whole.
Maybe it would be best to setup individual domains for each location instead? If they are not yours and they are their own entity, once they leave you could simply delete their machines based on an OU form AD, naming them based on their business doesn't make it any harder or easier to do that.
Segregate them by OU and then machine names are irrelevant. This topic has been locked by an administrator and is no longer open for commenting. To continue this discussion, please ask a new question.
