I have a fresh install of 5.0.7 - previously on 5.0.5. We upgraded our server to an dual Xeon processor with 2 gigabyte network cards on the board - an Intel and a Marvell Yukon. I have one HP 2300 laser printer w/Jetdirect plugged directly into the router - it is not attached to a workstation. I used the HP manager to install the printer. Any workstation can ping this printer or the SCO server, but the SCO server cannot ping the printer and correspondingly the printer does not print. I installed driver for the Marvell Yukon and the card showed up in Network Config Manager, but it would not ping the printer. After reboot, the Network Config Manager shows the Intel card (at which point I switched the network cable to the Intel); the Marvell card does not show, but the Marvell driver is in the hardware list without a MAC address and is not linked to the card. I have searched the SCO site and followed all instructions without any success. This is the exact printer that worked flawlwssly under 5.0.5, but it was on a Kingston card. The new motherboard does not have enough slots to install this card. Any help would be appreciated.
