That depends on what you want to do with Active Directory.

i want to add new user for internet connection .Kindly let me know the idea.Any help would be highly appreciated.

1st u need to know what is the use of ADUC(Active Directory Users and
Computers). Through ADUC u can add new users,groups and apply
restrictions on them .

i simple want to add New users .so that internet be available also
in My laptop .Kindly let me know the idea.Any help would be highly
appreciated.means i simple want to add the users in the domain.
if possible kindly let me know the process .what is need to be done
in my Windows 2003 server.any help would be highly appreciated.

For internet connection ,u donot need to create new users in domain environment. U create new users in ADUC inorder to have a domain user account which users can use to log into Domain Controller by using
their computers.

For internet connection ,simply plug an ethernet cable in the RJ 45 port of the NIC Card in ur laptop and make sure that the other end of the ethernet cable is properly plugged into a DSL Modem(Provided by ur ISP).

I hope this helps,

in my computer internet is working properly.but when i simple remove the ethernet cable from lan card.and reconnect the same
ethernet cable in mylaptop.and i did change in my laptop property from internet connection.i go local area connection.right click property->internet protocol->again property->and then i click on radio button->obtain

Kindly let me know the idea.Any help would be highly appreciated.

Firoz,

I am geting ur problem now, tell me 1 thing what happens when
u click on the radio button "Obtain IP address automatically"?
Do u get any error messege when u click on this radio button?

Make sure that u also click on the radio button "obtain DNS Server address automatically".

Please note once again that ur internet connection has nothing to do with ur domain.

Also tell me that what error messege do u get when u try to enter the domain name into the domain name field ?

Are u sure that in ur computer ,the TCP/IP configuration was set to dynamic?

Follow these steps:

1) R.C on LAN connection icon in the taskbar----->Status----->Support Tab on the top(Do u see IP address,Default Gateway and Subnet Mask details)? Does it say after "Address Type" :Assigned by DHCP?

You should do this before joining your laptop to domain

Also tell me is ur computer already joined to domain?
