start with giving the laptop its own ip address:
go into control panel, network dialing options, right click lan connection, properties, [if the laptop sees itself in lan, then its sfe to assume you have tcp-ip installed], highlight tcp-ip, properties, select: use the following ip address and give it something like 192.168.0.1
The subnet mask will probably then become 255.255.255.0
Don't worry about DNS.
Try and find the server on the lan now. If the server runs a dhcp server, you might have just taken its ip, so i suggest changing the ip to something like 192.168.0.50
If you have a small network, i suggest you give all the machines their own ip.
If you have done all the above already, then check:
- the laptop and server uses the same subnet mask.
- the laptop and server uses the same workgroup name.
- try using ping: in command prompt, try the command:
ping (the ip of the server). If you get a response you are halfway there, if no response, then you might want to start checking the cables, hubs-router etc.
anyway, try the above and return if no luck
