We have netware 6 SP3; Gateway PC with gig NIC cannot detect NDS and tree on the first login(you have to try a few times, sometimes the PC will reboot when you click on searching tree). Now all the queue printers on the same network will crash if one of the GIG NIC PC keeps searching trees(priters will lose connectivity to file server). You have to reboot server to get the printer back online. Any suggestions? we reapplied SP3, changed the NIC on server, still no luck. Thanks
