Disabling Auto IP Generation

Hi,

We have a big and growing network with Win-XP/2K/ and 98
OS. As we use mostly Novell services I want to disable
DHCP capabilities on these machines. For XP/2K/NT, I can
stop the dhcp client(the easy&dump way though).. but on
Win98 I tried adding a DWORD under.....
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\VxD\DH
CP.. added... IPAutoconfigurationEnabled :0
But still the PC is receiving the DHCP address. Any
Suggestions..?

Thanks in advance
Mehboob

That registry key doesn't stop the computer from being a DHCP client.
It stops the computer from assigning itself an automatic private IP
address when there's no DHCP server available. It's documented here:

Automatic Windows 98/Me TCP/IP Addressing Without a DHCP Server
http://support.microsoft.com/?scid=kb;en-us;220874

If a computer doesn't use TCP/IP, un-install the protocol. If TCP/IP
needs to be installed for some reason, assign a static IP address in a
private IP subnet that the network doesn't use.

Hi Steve,

Thanks alot for the reply.Removing the TCP/IP totally
makes it a real good solution, but incase infuture if we
want to assign a IP again we have to install and basically
its a hospital evironment having lots of PCs and my
manager (he is kind of hard to agree on good solutions)
want them to be having same kind of protocols and drivers
loaded(uniform)-so for me this may not be feasible
solution.
So secondly is there any way to disable or adding a
keyword somewhere in the registry so that that particular
machine(Win98) will not get an IP from DHCP server when
others do..?

Thanks a Mil.
Mehboob

You're welcome, Mehboob. I'm not aware of any such registry setting.
If you configure a network card's TCP/IP properties to obtain an IP
address automatically, it will do exactly that.

You might be able to configure the DHCP server to ignore certain
computers, possibly based on the MAC addresses of their network cards.
