Domain IP addressing scheme

[fargo]

Hi

I need to reconfigure an NT server and 5 desktops so that they use a different IP addressing scheme(they are all a 'single domain' and are 'statically addressed').

Can I simply 're-address' each of the machines and the hand them back to the users, or are there other considerations?.

Thanks in advance for any help!

fargo,

If these computers are not intended for public access then:
The keep it simple method:
Use either a 10.a.b.c. scheme or a 192.a.b.c. scheme.
example:

10.10.10.2 = gateway (usually a router)
10.10.10.3 = server
10.10.10.4 = printer1
10.10.10.20 = user1
10.10.10.21 = user2
10.10.10.22 = user3

If these computers will only be accessing 1 network then choose subnet 255.255.255.0 for all devices.

The gateway for all devices (except THE gateway) should be 10.10.10.2.

DNS depends on your internet connection and is significant to your setup. I imagine that you do not have your own DNS server and therefore must manually assign these. Ask your ISP for that information.

The more sophisticated method:
Setup a DHCP server (your server or maybe even your router can do these). Configure the DHCP server to distribute IP, subnet, and DNS information.
example:
ip subnet use
10.10.10.1/10 255.255.255.0 reserverd (network devices)
10.10.10.20/30 255.255.255.0 users
10.10.10.40/255 255.255.255.0 disallowed

Hope this helps

The answer to your question depends on what configuration changes you are making. If all you are doing is changing the IP address range, then it should be pretty straight forward. Change the addresses and reboot them.

Consider what other current resources all of these machines have ( will require ) access to. Where are network printers, mail servers and file servers located?

If they will need access to resources that are on the current network, you will probably have to install a router.
The best solution in this case would probably be to install a second network card in the server and select Enable IP Forwarding in the Network Neighborhood\Properties\Protocols\TCP/IP Protocol\Properties\Routing tab.
