Connect to Domain

create an account on the domain controller (server) for the win 98 computer name and the win98 user.
on the win98 box, you must have Client for MS Netorks installed (Control Panel/Network/Add Client). you must also have matching protocol installed, with valid ip address and same subnet mask as server...try dhcp if you don't know what to use...
you configure the win98 box to logon to the domain thru the properties of Client for MS Networking. right click Client for Ms networking, click the radio button next to 'logon to DOMAIN' and type in the domain name. 'quick logon' should be fine. click apply. make sure ms client is your primary logon.. reboot computer...

The above answer assumes that you have a network adapter (nic) in your computer and that it is properly functioning and the cables are connected.

If you do not have a network card, you will need to purchase one, connect it and install the drivers for it. Then you need to connect the cable to the nic and on the other end, the cable needs to be connected to a hub/switch/router/patch panel etc. which ultimately feeds off of the domain controller (or server).

So basically, you need:
1) a network adapter
2) cable
3) drivers
4) administrator login/password authorized for adding users to this domain that you wish to connect to.

If you have all of the above, then you should be able to join a domain by configuring the Network icon in Control Panel.

If the domain is DHCP enabled (dynamic host configuration protocol), then you will not need ip address/subnet/gateway info. But if the domain is not DHCP, then you will need to provide an ip address, subnet mask and gateway (yourrouter address, or server, depending on how your network is setup) that you can use on your network.

You may need to talk with your network admin.

one other thing to look at is the workgroup that your computers are in. here we have to have the workgroup same as our domain. where you find the work group is right click Network Neighborhood - properties and go to Identification. The domain part is if you right click network neighborhood -properties and click Clients for Microsoft and click properties. hope this help out!
