Last year we made up a Dos disk that connects to our Samba server, to permit us to download (using "ghost") a disk image to our Dell Optiplexes. We can seem to get last year's boot disks to load; specifically, netbind complains that it can't bind, hardware failure. This year's Dells come with 3Com 3C905b PCI Etherlink cards...last year's model had the 3C905 version. I don't as much as I should about the protocols used in Dos and am at a loss where to start. The boot disk appears to be loading NDIS LanManager stuff, starting with LH net initialize netbind.com LH umb.com LH tcptsr.exe LH tinyrfc.exe LH nmtsr.exe emsbfr.exe LH net logon .... If anyone currently doing this can tell me anything about this process I might be able to ask DELL or 3Com about possible card changes. Thanks, Dan
