We've run out of IP addresses on our network so we want to change our subnet
from to to open things up a bit.

I thought all I'd have to do was change the subnet on the servers and
reinitialize, then do the same on any other devices (printers and switches,
right?)but when I started to change the subnet mask on the servers I can't
ping anything.

We've got 4 NW6.5 servers (including one Groupwise 6.5) all behind one
BorderManager 3.8 server which is a VPN, Proxy and firewall server.

What am I doing wrong? thanks.
