I have 2 series of IP.I want to make a domain controller in windows server 2003.all clients system are XP.I want to know can i make a domain server.if yes how its is possible ?
I'll assume you want to create a new domain; this is quite a simple operation, involving some basic steps:
After the domain is up and running, configure each and every client computer to use your new DC as its DNS server, and then join it to the domain.
If by "I have 2 series of IP" you mean you have two subnets...
Then yes you can - the Domain controller doesn't care what IP address a computer has* it only cares that it can reach it (or rather the computer can reach the DC) - "2 series of IP" will not make a difference.
To make a Windows 2003 server a domain controller simply go Start->Run->dcpromo and follow the wizard.
*Ignoring sites/security/NAT/VPN or any one of the thousand things that could get in the way.
