(A) You assign hostnames (PCs) and IP addresses under the "Hostnames and addresses" panel in server-manager.
You need to know the PCs hostname (the name you gave the PC) and its MAC address(looks like A0:B7:C0:D9:45:EF) and the IP address you want it to have.
For Windows PCs, Start/Run "cmd" then enter "ipconfig /all"
For Macs, try this
http://www.wikihow.com/Find-Your-IP-Address-on-a-Mac. If that does not show the MAC, try adding "/all" to "ipconfig"
For Linux, get a terminal window, type "ifconfig"
(B) logon to you Wireles box and turn OFF the DHCP setting. This means make the WAP
NOT give IP addresses out. Your laptop should get an address from the SME. You may also set your Outlook to look for the server by IP not hostname. eg POP server = 192.168.1.1 instead of mail.myserver.mynetwork
