How do I know if a server is a domain controller?

I have just been moved into an area where I am totally out of my depth. Just trying to dip my toe into the network arena.

I have two "servers." One is MS Server 2000 and the other MS Server 2003. How can I know if either is a domain controller? How can I find the domain name?

    Hi BobGipson,

    open up active directory and check under the domain controllers OU

    you can find the domain name by right clicking my computer and selecting properties - network ID TAB

    Easiest way to tell - at logon (when you press Control+Alt+Del) make sure the "options" are displayed so you see a "Logon To:" section.

    Clilck it so you see the list of items you can logon to - if there is NO entry with "(this computer)" in it, then it's a domain controller (you cannot log on locally to a domain controller.  Further, the domain name is the (other) name listed in that drop down box.

    Is it a domain? If a workgroup, no active directory, so you could right click on my computer choose properties and then computer name. It will show workgroup and workgroup name if not a domain, or domain and domain name if a domain. If a domain follow Jay_Jay70's lead.

    Assuming you don't have administrative privileges on the servers, you could try opening a commandprompt and typing:

    nbtstat -a <servername>

    If you see any entries in the list with <1B> or <1C> in the second column, you know that it's a domain controller.
    The column in front of that shows you the domain.
    Granted, it's a bit of an old-fashioned method, but it still works like a charm :)

    Another way to discover what DC you're using is opening a command prompt and typing:

    echo %logonserver%

    If you are an administrator, you've got loads of options like the ones mentioned in the other answers

    it depends on the conditions if u r a user then if u wanna find out ur domain name just chk before logging on that on which domain ur logging on n c which machine has shared a folder named sysvol & netlogon on the network
    on the other hand if ur administrator than in active directory users and computer pane u can find out that if ur machine is domain controller or not u can also chk my computer properties n thn computername computer with management console of active directory user and computer has a good chance of being domain controller so all in all there r many ways of finding it out.
