The definition and relationship of Ad/dns/dhcp/iis/wins's image

Ad-is actually a database that includes all the information, and in real life compares it to a police station, all the information must enter his database (including the name of the person (computer name, account number, password, etc.)

DNS is the establishment of a relationship between the name of a good memory, such as your home location with GPS positioning of the east longitude 20 degrees, North dimension 160 degrees, this to everyone memory inconvenient, then DNS will give you a "East Street 1th" name to you, the next person to register the name of the time will inquire he wants to register "East Street 1th" exists, if the existence of a second person can only register other names and related to his dimension convenient for everyone to inquire;

IIS is just an application, just like the word we use, but word is used to process text typesetting information, which is used to manage the information of the website;

The role of the WINS service and the ultimate goal of DNS is to resolve the name to an IP address, but the difference is that DNS is done through the TCP/IP protocol, and WINS is accomplished through a NetBIOS protocol. If your network does not have NT or 98 and previous machines you can only configure DNS without having to configure the WINS service, unless you also have a long time application that requires the support of the WINS service.

DHCP is an IP management agency, each computer on the boot, the network card will be in the entire Internet yell (broadcast) My DNA "MAC" is 11:22:33:44:55:66 I need the number, the DHCP received will be based on the rules, from 10 number in the division to him, including IP , masks, gateways, DNS, etc.! AD and DNS are very related, the ad is completely dependent on the service is DNS, the creation of AD to build the DNS service, the creation of AD can build the enterprise's IIS services, including Web and FTP, and the use of DHCP protocol also requires DNS.

If it is an enterprise to build a directory of AD activity, then DNS,IIS,DHCP can be said to be needed

DNS, domain name resolution system, is not a simple service, but also a broad sense of the global domain name resolution system, by a number of DNS servers and DNS member machine composed of such a computer organization.

The role of DNS in the domain environment:

1, named after the DNS standard (domain name)

2, support DC (when creating a DC, to have the appropriate DNS support)

3. Locate DC (when joining Domain, help earth person to find DC)

With the above knowledge preparation, let's take a look at some of the points to add to the domain:

1, contact the problem: A.ping pass DC, DNS server (to ensure that you can communicate with DCs, DNS servers, to join each other's international you must be with each other's government "DC" and the Embassy "nearest DNS server" contact) B.dns resolution DC (through DNS to know where the DC is) The embassy tells you how to find the relevant personnel department, of course, will tell you the address of the DC ")," You can use the nslookup command + domain name to detect the correct client DNS settings.

2, Permission issues: When joined the domain, will be prompted to enter a corresponding user name password to join the domain permissions. There are a lot of people here who think that only the administrator can pass the domain validation, so they always use the administrator to verify the join domain. In fact, using a normal domain user is also possible, and newly created domains users can authenticate to join the domain for Non-domain member machines. Domain, just like a country, is needs to develop, can absorb the more insight, the country will be stronger, so every national, have the right one wildfire.

3, landing problem: After joining the domain is not all right, many friends directly with the administrator landed. As it is, the move landed on the local computer. You need to click on the option to log in and select the domain you are joining in.
