Create an Server Image

I have to create an image of a server and I am stuck. I have only looked on while someone did this before and so I don’t want to proceed without being sure of my steps.

Here is what I recall:
1. Insert Network Book Disk
2. Press F12 to Login toNetwork Drive
3. Login with Username and Password
4. Type Net use X:\\yyyy\Image$ (where x is the drice and yyyy is the server name)
5. Type x:\Ghost\Ghost

Can someone tell me if these steps will help me achieve my object and, if not, can you point me in the right direction.
