Turiyain,
SME is adminsitered from another machine, using a web browser (Firefox, Internet Explorer etc). That is where you get the gui interface you see in the screen shots of SME.
You need to browse to
http://your-server-name-or-IP-address/server-manager and that will get you the Admin web screens. It will first ask you for a username/password....you may also get a Security Certificate error as a first response - if so, just accept the certificate.
eg If you server is "frodo" and its IP is 192.168.1.1, then the following are equivalent:
http://frodo/server-manager (this one may not work if WINS resolution has not yet happened)
http://192.168.1.1/server-manager (this one will always work
I suggest you get down to reading the manual before you try anything else - it answers 95% of you questions - and gets you into asking even more as you become more experienced and want to try adding things to SME.
Remember, when aslking questions, give as much detail as you can about what system you have (PC system, netowrk config, OS etc) and what the problem is - what you want to happen, what you have done and any error messages you have had - and extracts from the logs if you can. It all goes towards helping those who can help you.
Good luck - and keep playing.
