Hello Decstation Managers,

I have a decstation 2100 running ultrix 4.3 which once served
as our campus primary name server. It also served as a decnet/ip
gateway. A month ago we shut this system down & gave its hostname
and ip address to another machine which now serves as the name
server.

Recently, I learned that we were premature in taking away our 
decnet/ip gateway.

Here's my problem: I need to bring this system back to life ... off
the network, change its ip address & hostname then hope that its
former decnet/ip gateway functionality still works when I reboot it
on the network. Since the decnet/ip gateway feature of this system has 
always been a mystery to me, all I can do is hope it works. 

Does anyone have any advice, suggestions, comments, previous experience
or other information you can share on this topic?

Thanks,
Martin Meadows

Ps.
I believe I can change /etc/hosts and /etc/rc.local to get the hostname & 
ip address changed (thanks to advice from digital/compaq guru: Al).
Is there anything else?
