What did the server say ? It should work, and is working for others.
When you added the second NIC, the problem you got is the one I had
in mind when I wrote "it will complicate matters if you do" !
Have you defined both subnets to be members of a shared network ? If
not then you'll never get it working right.
WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon
part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a
dead HD and need this CD so I can replace the disk and re-install the
printer OS on it.
This is NOT the same thing as the printer drivers to load on the
computer - there's no problem there.
If anyone knows where I might get hold of one I'd be grateful -
requests to Canon drew a blank, it's been out of support for years.
Alternatively, if anyone has one of these and would let me image
their hard disk ...
