@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 .
