I am new to this; so bare with me. It is a windows 2003 server. I am guessing it should not matter what application the server is running. If one server dies that the other one takes over operations. PS i will have a file and web server. Thanks

Need to do: I want to have two server that are identical to each other, the only difference being one is server is slower then the other. If one server fails I want to automatically switch to the identical backup server. Is there any software that someone can suggest? Thanks
