Do you want the easy way, or the Real Novell Man's way? LOL!!!
First off, are you using INETCFG to deal with your LAN Adapter and Protocol related configurations? You will know this by looking at your AUTOEXEC.NCF file. If you have a # symbol in front of the LOAD and BIND statements of your NIC drivers, then you are using INETCFG. If you don't have a # sympbol in front of the LOAD and BIND statements, thats even better!
1. From the Server Prompt, type "LOAD TCPIP"
2. Next, type "LOAD <NIC Driver> SLOT=<SLOT#> FRAME=ETHERNET_II NAME=NAME_1_EII" (This will load the NIC driver with the proper protocol support for TCPIP)
3. Next, type "BIND IP NAME_1_EII ADDR=<IP ADDRESS> MASK=<Subnet Mask> GATE=<IP Address of Next Hop>
That will do it.
Good Luck!
