Its very easy to add GUI for Ubuntu server edition,
U have to follow the following steps for the same,
After installing the Ubuntu server Edition,Login as root by the following command u will get the root previlage,
sudo passwd root
It will ask u the existing password and followed by twice the nex Unix password for the confirmation,
then you have to logout using the command
logout
now u will get the root previlage with
#
prompt,
from there u have to type,
vi /etc/apt/source.list
then uncomment all the lines which ends with "universe",
write it and quit the file
the you have to type the following command,
apt-get install gnome
it will start install the gnome enviornment for you,
followed by
apt-get install ubuntu-desktop
apt-get install KDE
If u needed,
after finishing the download,it will start install the file,
once the same is finished u will get the prompt,
#
from there u type
startx
Now u can see the wonder,Its a GUI OS now,

Creating Domain Controller on Win Server
Creating the first Windows Server 2003 Domain Controller in a domain
Preface:
One of the greatest features of Windows Server 2003 is its ability to be a Domain Controller (DC). The features of a domain extend further than this tutorial ever could, but some of its most well known features are its ability to store user names and passwords on a central computer (the Domain Controller) or computers (several Domain Controllers). In this tutorial we will cover the "promoting" (or creating) of the first DC in a domain. This will include DNS installation, because without DNS the client computers wouldn't know who the DC is. You can host DNS on a different server, but we'll only deal with the basics.
Method:
Click Start -> Run...
Type "dcpromo" and click "OK"
You will see the first window of the wizard. As it suggests, I suggest reading the help associated with Active Directory. After this, click "Next"
Click "Next" on the compatibility window, and in the next window keep the default option of "Domain Controller for a new domain" selected, and click "Next"
In this tutorial we will create a domain in a new forest, because it is the first DC, so keep that option selected
Now we have to think of a name for our domain. If you own a web domain like "visualwin.com", you can use it, but it isn't suggested because computers inside of your domain may not be able to reach the company website. Active Directory domains don't need to be "real" domains like the one above - they can be anything you wish. So here I will create "visualwin.testdomain"
Now in order to keep things simple, we will use the first part of our domain ("visualwin"), which is the default selection, as the NetBIOS name of the domain
The next dialog suggests storing the AD database and log on separate hard disks, and so do I, but for this tutorial I'll just keep the defaults
The SYSVOL folder is a public share, where things like .MSI software packages can be kept when you will distribute packages (as I said, AD has a lot of different features). Once again, I will keep the default selection but it can be changed if you wish to use the space of another drive
Now we will get a message that basically says that you will need a DNS server in order for everything to work the way we want it (i.e., our "visualwin.testdomain" to be reachable). As I mentioned earlier, we will install the DNS server on this machine as well, but it can be installed elsewhere. So keep the default selection of "Install and configure", and click "Next"
Because, after all, this is a Windows Server 2003 tutorial website, we'll assume there are no pre-Windows 2000 servers that will be accessing this domain, so keep the default of "Permissions compatible only with Windows 2000 or Windows Server 2003 operating systems" and click "Next"
The restore mode password is the single password that all administrators hope to never use, however they should also never forget it because this is the single password that might save a failed server. Make sure it's easy to remember but difficult to guess
Now we will see a summary of what will happen. Make sure it's all correct because changing it afterwards can prove to be difficult
After the previous next was clicked, the actual process occurs. This can take several minutes. It's likely that you will be prompted for your Windows Server 2003 CD (for DNS) so have it handy
If your computer has a dynamically assigned address (from DHCP) you will be prompted to give it a static IP address. Click ok, and then in the Local Area Connection properties, click "Internet Protocol (TCP/IP)" and then "Properties"
In the next window select "Use the following IP address" and select the information that you will use for your domain (and 127.0.0.1 for the primary DNS, because your computer will host DNS. I still suggest setting up an alternate as well.) Click "OK" and then "Close" on the next window
And after a while you will see

Windows XP Login Logout Loop
Problem: The PC (which runs Windows XP with SP2) starts normally. The Windows splash screen appears correctly and then the login prompt correctly loads. You can then enter your user name and password like normal, but as soon as you try to login you are IMMEDIATELY logged back out again. The desktop doesn’t even load. It moves immediately back to the login window where you can then enter your user name and password again. No matter how many times you try to login you always experience this immediate logout. Even if you try to login to the computer in safe mode you still experience the same problem. This problem is documented on Microsoft’s website here.
Solution: I’m sure this behavior can be caused by many different problems, but the most common cause is a virus. If you’re familiar with the Windows registry, this virus changes a few registry key values that makes it impossible to login to your computer. If you’re not familiar with the registry, don’t panic. I’ll post links to a few articles that very clearly explain how to fix this problem. Basically, the virus makes two very simple changes to your computer that render it useless. In order to fix the problem, you have to change these two things back to the way they were while your computer was working.
Easy Fix: The “easy” solution to this problem can be found here. In order to use this fix you have to have your Windows XP install CD. This is the CD that contains the files necessary to install the operating system on your computer. You probably have this disk stashed in a drawer somewhere. You should note that there’s a difference between the Windows XP install CD and the recovery CD that may have shipped with your computer. It’s actually possible that when you bought your computer that it didn’t actually come with a Windows XP install CD. Sometimes computer manufacturers will only ship you a recovery disk, which is altogether different. You need your Windows XP install CD so that you can run an application called the Recovery Console. The link above should provide documentation on how to use the Recovery Console. Unfortunately, this fix didn’t work for John’s computer, but it may work for yours.
Slightly Harder Fix: This fix is the one that ended up working to fix John’s computer. A detailed explanation of this fix can be found here. It requires you to have access to another Windows PC with a CD burner (even if it’s a friend’s computer). You have to download a program called BartPE, which is one of the greatest recovery tools that exists. For this particular problem, BartPE will enable you to quickly change the two settings that the virus messed up. You may need a Windows XP install CD for this method as well. But it may be possible for the program to find what it needs from your friend’s computer without having to have access to this disk.
