1. How was this network set up before?
2. Is the server a DHCP & DNS server or just a file server?
3. Are there no diagrams/plans/information on the previous setup?
3. Are the systems set up with static or dynamic IP's?

More information needed than what you have given to help

A cross over network cable is only used when you are connecting only 2 computers together without a router in between them. If you are connecting to a router, on all computers you need straight through cables to the router. My home network is only 2 computers and i use a cross over network cable. It eliminates the need for a router.

programming_pat1. How was this network set up before?   The first time setup.
2. Is the server a DHCP & DNS server or just a file server? I don't know. (sbs 2003)3. Are there no diagrams/plans/information on the previous setup?

there are two type of wiring.568A & 568B
Why these two are obtaining?What may I use?Pls help.
Previously there are five pc & they connected through switch.As I saw them they all different.So I want to know the STANDARD method for crimping.
straight cables are used when you network more than 2 nodes or pc via a network switch and you will to use crossover if only 2 pc's  are on the network.more or less you know the arrangements of the wires and you have the idea the difference between these 2.

gross_earnings thank you.
from one switch to other switch there is cross over cable. Right  You're going to need professional, on-site help to get the network set up properly.  No amount of forum time or help is reasonable.   

Please find a professional in your area to help.
