can someone just send me a script and tell me the method how to do it. please it will be of a real help. i have read a few tutorials online but i do not exactly want to take risk on the network. and so i request u to help me out.

Risk .Many people out here have learnt it that way. And many people out there have done a good job of documenting and u think that reading that and trying it out on ur network is a risk. If that is so then why don't u consider the scripts which u r asking , a risk? Every network is different from other. Please read the tutorials and try them out and then if u land up with problems then there are people who will help u out. But don't expect a ready made script.Use the readymade tutorials
