I just want to know that how should i connect 6 PC's with each other using LAN. With the help of RJ45 wires and Switch/Router. What i want to do is to create 1 pc a server and other 5 should be connected with that and with each other as well but the files shared by server should not be deleted by the other pc connected to the server. Almost all pc have windows 7 in them. The internet as well as LAN should work on every pc at a time. Please suggest me something.
Connect all of your computers (server and clients) to a router that has a built-in switch. Almost all modern consumer routers have a built-in switch. Make sure that all of them are able to connect to the Internet. Now since you're running Win7 on all of the machines the easiest way to do a server-client setup is to create a Windows 7 Homegroup on one PC and then have all the other computers also join that Homegroup. You can then designate a folder on the server to share with the homegroup and set it so that the other members in the homegroup (the client computers) only have read access to the folder and not write access. This way all clients can access the files on the server and nobody besides the server can delete them.
