To find your domain name in Windows 11, press Windows key + R, type sysdm.cpl, and select OK. On the Computer Name tab, the name next to Domain is your domain. If the label says Workgroup instead, the PC isn’t joined to a domain.
You can also check from PowerShell or Command Prompt, as shown below. These steps only read the setting; they don’t join a domain or change anything. Your PC’s domain is different from a website domain or the domain in your email address.
Find the Domain with PowerShell
- Open Start, type PowerShell, and open Windows PowerShell. A normal window is enough; you don’t need administrator rights.
- Paste
Get-CimInstance Win32_ComputerSystem | Select-Object Name, Domain, PartOfDomaininto the window and press Enter. - Read Name as the computer name. Check PartOfDomain before treating the Domain column as a domain name.
- If PartOfDomain is True, record the Domain value exactly as displayed. If it is False, the computer is not joined to a traditional Active Directory domain; the Domain column shows its workgroup.
Microsoft explains these fields in its Win32_ComputerSystem reference. A workgroup can have a name that looks like a company name, so go by PartOfDomain. For a quick check in Command Prompt, run systeminfo | findstr /B /C:"Domain" and read the Domain line.
View Membership in System Properties
- Press Windows key + R to open Run.
- Type sysdm.cpl and select OK to open System Properties.
- Select the Computer Name tab if another tab is active.
- Look for Domain or Workgroup and read the value next to that label. Close the window when finished.
If you see Domain, the PC is on an Active Directory domain; if you see Workgroup, it isn’t. You don’t need the Change button, which is only for renaming the PC or joining a domain, as Microsoft’s domain-joining instructions show.
The Full computer name field is a different value. Copy the membership value when IT asks for the domain, and include the computer name separately if requested. Settings > System > About is useful for device information, but Device specifications doesn’t always show a domain field, so System Properties is the more reliable place to look.
Check Microsoft Entra Join Status Separately
An organization can connect a device to Microsoft Entra ID, formerly Azure Active Directory. This cloud join is different from a traditional Active Directory domain join. A PC can also have both through a hybrid configuration. Seeing a work or school account in Settings does not by itself resolve which join state applies.
- If IT needs the device’s join state, open Command Prompt in your normal signed-in work-user session.
- Run
dsregcmd /status. - Find the Device State section. Read DomainJoined, DomainName when present, and AzureAdJoined.
Microsoft’s dsregcmd reference explains the fields: DomainJoined YES means an Active Directory domain join; AzureAdJoined YES means a Microsoft Entra join. Both YES indicates a hybrid join. DomainName supplies the domain for a domain-joined device. A cloud-only join can therefore coexist with no traditional domain membership.
WorkplaceJoined appears under User State and refers to Microsoft Entra registration for the current user. Registration is not the same as Entra join. Give IT the relevant fields and the command’s error, if any; avoid posting the entire diagnostic output publicly because it contains device and organization details.
If You Cannot Find a Domain
Seeing a workgroup is normal and doesn’t mean Windows is broken. Connecting to company Wi-Fi or signing in to a work website doesn’t mean the PC has joined an Active Directory domain. If your organization expects the PC to be on its domain, ask IT about it rather than changing it yourself.
If a command is blocked or shows an error, use the System Properties method instead. If neither works, give IT your computer name and tell them which checks failed.
To connect a computer after IT confirms the correct domain and authorization, see our Windows 11 domain-joining guide. Joining has edition, permission, and network requirements and can require a restart. Finding the existing name is a separate read-only task.
Common Questions
Is the domain the same as my computer name?
No. The computer name identifies the individual PC. The membership label identifies its domain or workgroup. Record both with their labels if support asks for them.
Does this show my website or email domain?
No. This article checks Windows device membership. A company email suffix or a website address may look like a domain name, but that doesn’t mean the PC is joined to it.
Do I need to restart after checking?
No. These checks only read settings, so you don’t need to restart.
