Hope someone can help. I need to change the subnet mask on my lan in order
to
have more IP address' available. I am running server 2003, active
directory
and ISA. I only use static IP addressing, DHCP is not in place. The
configuration I am using is:

Internal Network Server NIC:
10.0.0.2
255.255.255.0

Which allows lan IP address' of 10.0.0.1 thru 10.0.0.250

I want to change the subnet mask to 255.255.254.0 , which will open up
10.0.1.1 thru 10.0.1.250 on the network for use. I would then have
10.0.0.1
Thru 10.0.1.250 range of IP address on the network correct?

I would change the above NIC in server 2003 machine subnet mask to
255.255.254.0 as well as all clients, switches, printers etc.

What else should I be aware of when doing this considering the use of
active
directory, ISA and others?

Any help is greatly appreciated. Thanks.
