1. Go to the Microsoft Windows Server 2003 download section at http://www.microsoft.com/windowsserver2003/
downloads/tools/default.mspx. Or, if that link does not work, visit http://www.microsoft.com/ and search for "Windows 2003". Once there, choose the "Downloads -> Tools" link.

2. Select the link "Windows Server 2003 Resource Kit Tools".

3. Click the "Download" link. Choose to register or not, depending on your choice, and follow the on-screen instructions to download and install the product. The default install directory is "C:\Program Files\Windows Resource Kits\Tools\".

Once the Windows 2003 Resource Kit is installed, you may need to reboot your machine for the directory "C:\Program Files\Windows Resource Kits\Tools\" to be added to your path.

Now that the tail command is available, to see the online help, enter the following DOS command:

tail /?

Here is a command summary:

C:\>tail FILENAME

Display the last ten lines from file FILENAME. For example, to see the last ten activities made by the Windows Update tool, issue these commands:

C:\>c:
C:\>cd \windows
C:\>tail "Windows Update.log"

C:\>tail -n FILENAME

Display the last 'n' lines from file FILENAME. For example, view the last 20 lines in the Windows Setup log:

C:\>c:
C:\>cd \windows
C:\>tail -20 setuplog.txt

C:\>tail -f FILENAME

Keep accesing FILENAME, displaying new lines as necessary.

To see this feature in action, open up a new file in Notepad, write the word 'hello, world', and save it as c:\test.log. Keep the file open in Notepad. Now, issue the following DOS commands:

C:\>c:
C:\>cd \
C:\>tail -f test.log

You should see the word 'hello, world' in your DOS prompt. Now, go back to Notepad and write the text "Process executed." Save the file. The DOS prompt should now say "Process executed." Whatever you add to the file in Notepad should then appear in your DOS prompt until you terminate the command.
