The limitation on 3.51 was in using the Control Panel to input the IP
addresses, nothing more.

The Control panel allows you to input up to 5. To add additional addresses,
use regedit32 to open the appropriate registry parameter and simply add
additional IP addresses, one per line. I don't recall the exact's the one for the NIC you've added. On my system, it was eln33
or something similar for an Ethernet 3C509...

This worked fine on NT 3.51 SP2. When I applied SP5, nothing broke (that I
know of <g>)

None that I know of.

If you need more info, please email me privately, I may have a writeup I
can either email or fax you...
