I installed Lepide active directory management in my windows vista to learn using active directory for my Networking class, problem is i could not add domain ,I'm using wireless connection with 3 other pc using same kind of connection with router ,tell me how i can do it tech guys? thank you.

hey,where are IT guys???

Since you have Microsoft operating system and your attempt to install Active Directory, here are the tips for you.

1. You need to have atleast OS 2000 server or 2003 Server or 2008 R2 Server with enough memory. You can have full blown 2008 R2 Server for free for 180 days from Microsoft website.

2. Then you need to install Active Directory Domain Service using dcpromo.exe from command promt. It will install new domain controller or Active directory in new domain in new forest. It will also install a new DNS server in the new domain controller.  If you need more detail in depth in multi domain or multi forest. this will be more coplicated. Let me know if you want to understand more.

Note: You are required ( recommended) to set up static IP address with default gate way IP address. Your default gateway is the IP address of your router. Keep in mind you need to have physical connection to your computer or Server with OS mentioned above from router. Do you know how to set up static IP? Make sure you know what ipconfig is and ipconfig/release and ipconfig/renew commands are. Let me know if you need assistance.

3. Once Active Directory in new domain is set up, you can have client computer or member servers join this domain. Once you are done with joining the computers in new domain, you can login to the new member computer in the new domain environment.

4. If you are doing for learning purpose, you don't need three physical computers. You just need to setup HyperV or VMware so that you can have multiple computers with various OS or member servers with various server OS in virtual environment aka cloud.  Complicated? Let me know if you need more assistance.

@Nepalibhai  ...thank you very much for your great advice, i did spend a lot of time today trying to set up free windows 20003 server from CNET download as i don't have CD for this , but i got error "Not enough server storage to process this command" ,even i created "IRPstackSize" and value to "50" didn't work,Now i'm following  your steps. and yes it's for learning purpose only, and my laptop have 32 bit memory size only,can you suggest me which of the thing you mentioned will be better to install ,
               Currently  i'm  downloading ...the 2008 R2 server...and let's see how it goes,
i certainly need your advice ,plz keep reading my post.,you are genious by the way.thank you.

Since you have hardware constraint, you have to go different approach. You can't install OS Windows 2008 R2 64 bit.
Hence, best approach is following:

1. Download and install VMware player from their site and install it.

2. Create virtual machine in that VMware player environment and install OS Windows 2008 R2. It will take it even though your it is 64 bit OS.

3. Set up Static IP and Default gateway IP in IPv4 properties from control panel.

4. Then run dcpromo.exe from command prompt or powershell environment. It will create new forest and new domain and new domain controller aka Active Directory.

Do this and let me know. By the way, are you a student or IT professional? If you are a college student these activities may be beyond your requirement for your classes. These tasks are for actual enterprise environment. If you know these things now, you will make heck lot of money later. Good Luck

@Nepalibhai...I downloaded windows server 2008 R2 ..luckily setup went fine,only sound is not working ,tried to install new realtek driver but it says"realtek controller not found...something ...on sleep mode " error ... , Active directory is installed ,and now i'm trying for the Static IP address setting.....is there any difference between IPV4 and V6 ?
         Well I'm trying to be IT professional ...still not in market but trying ....let's see how it goes, also i was thinking about certification ,well actually i like networking rather than programming which i'm not good at, Also I would like to hear your thoughts on Networking field ,like any college i can join for Networking field ..or like that ...Also tell me how could I set up further ...like i think next could be like Group policy right? 
anyway keep giving me advice ,tx.

I did setup static IPv4 address as well as default gateway.

but can't find DHCP in admin tools....

cool kale bro,

The set up NepaliBhai is explaining is completely for professionals in companies. It has to do with System Admin in companies.
Are you working as a System Admin or Network Admin? What is your background. Are you still in the college or looking for job? I am also very interested in this line.
Please give me some advice on how to be in this profession?

Thanks

@dhotiprasad... you 're explaining me about those explanation made by nepalibhai is professional this and that .....so how come you are asking me the advice ...doesn't match your explanation right?
 well i've IT bg , and learning in college is not enough so i'm learning from professionals to be professional.

@cool kale (nice name, btw) -

Your enthusiasm looks sound, but you might not be able to get dedicated advice from someone for too long, especially when it comes to basics such as difference between ipv4 and ipv6,  setting up DHCP server, etc. It's good that some fellow Sajhaites have been kind enough to lend a hand, but it's a solo drive for you, in long term. Things get more complicated as you move further, and there'll be a substantial amount of research you're going to have to do in order to reach a level of comfort.

If you're into Microsoft and domain management, you first need to be familiar, and comfortable with a standalone server. There are terminologies and a handful of logic associated with those terms. You need to develop an attitude to learn their relationships and dependencies. Microsoft offers certifications to help master those skills (formerly called: MCP, MCSA, MCSE etc with their respective milestones). You should plan on aiming for those, and during the process of tackling each certification, you'll leave behind a good chunk of your confusion.

From Windows administration perspective, you'll have enough skill-set to understand "Networking" by the point you get to MCSA (or whatever it's currently called) level. If core Networking (routing, switching, subnetting, network designing, etc) becomes your passion during the journey, you can always choose to proceed that way; your Windows knowledge will still come handy when needed at some point in life. Cisco materials provide a great head-start all the way from ABCs of Networking to making you a go-to guy for ISP and large firms' operation and management. So, despite being vendor specific, cisco certifications lead you a long way. 

And last, but not the least --- I'd look for books on Amazon, or at a nearby bookstore to see if there's anything valuable out there that would help me get around  the hard way and learn stuff, making it a fun read.

To answer your questions:

but can't find DHCP in admin tools....

-DHCP is a server function that needs to be enabled, and a scope defined. Not all Domain controllers are DHCP servers. In your setup, if the router is handing out IP addresses, then that's your DHCP server. If it's important for you to set DHCP up on your DC, then the following article might help you:

http://www.windowsnetworking.com/articles_tutorials/How-to-Install-Configure-Windows-Server-2008-DHCP-Server.html


my laptop have 32 bit memory size only

-That can't be true! If you're referring to CPU, then 32 bit CPU is good enough to install a win server. (I believe it'll not be supported post Win 2008 R2). It looks like you've already installed Win 2k8. So, you should be all set with that.

i think next could be like Group policy right?

Once you have domain clients manageable by the DC, then sure.

is there any difference between IPV4 and V6

Yes. IPV6 is a lengthier representation of IP addresses, designed to facilitate increasing needs of new IP addresses.
You can get by without knowing ipv6 for some time, as it's not yet been widely implemented in the US (assuming you're in the US).

sound is not working ,tried to install new realtek driver but it says"realtek controller not found.

That's the last thing I'd worry about on a domain controller. Trust me, that won't haunt you on your way.

@saajha ..You are absolutely right and tx a lot for your helpful tips and suggestion .Oh yeah i did  learnt more things about tcp/ip and the version ipv4 and v6 ... . and yeah i was able to install active directory and got idea from there to install other services and roles. Only thing was i couldn't install Hyper V player as my cpu didn't support virtualization technology. i set up Remote desktop ,IIS , and so on but remote desktop is having problem even thought it can ping local computer (client computer) but can't connect remote desktop .
     And yes i'm in the process of following certification ..and i do like cisco networking as well..so overall i like networking (microsoft ) and cisco ,
        tx a lot again for ur great suggestion .
