Hey there,
There are certain things to be denoted long before you set up your network the most important of which is What is the need for the server, is it to share fewer printer resources, file sharing, is it going to be an application server is it purely for data security and backup purposes.
One other major factor is Budget, Server software does not come cheap and for the majority of them for a ten user licence it will cost you in excess of ?2,500.
Here's a few examples:-
If the requirement is for users to share data between themselves with no real security requirement, then a simple logical peer to peer setup can be utilised.
You would buy a small hub to accomodate all the devices and assign an IP address to each device within a valid range i.e. 192.168.0.1 - 10 for your PC's subnet mask 255.255.255.0
Gateway address not required.
On each 98 PC enable File and Printer sharing in Networking properties and woala you should be able to see each of the other PC's.
The information I have supplied here is a rough guide and although you felt that user Valis was abusing you he has a valid point.
Networking is more than just a plug in and off you go environment, and if this is all new to you, your going to have a steap learning curve.
Server Operating systems although they appear just like ordinary OS's for all intent and purpose (Note This is relecting purely on the Microsoft range of Server Os's to their Client counterparts) But are far from simple to get your head round they require study and a lot of trial and error especially if this is your first server without support you could be in for quite a time.
The first question above should give you the type of netowrk and server i.e. File server, Print server, Applications server, Internet gateway. thus decide what your requirement is before designing your network.
Hope this helped
