DNS Search Order

Can anyone advise how to set-up the DNS search order within SuSE 8 as one would for Windows? I have a Win98 box running both Vpop3 (email server) and Vsocks Light (proxy server and firewall). Yes I know this is available with SuSE but I have got to get certain things working and know how first. I am able to both use and log into Vpop3 but not able to access the Internet.
