DHCP question

Hi everyone,

I setup DHCP on our Win2003 server for our network PCs' IP address.

My question is that I changed Default Gateway x.x.x.99 to
x.x.x.5(we have two lines go out, one is .99, the other is .5) on Win2003 server, but it seems that all PCs still go out by using .99. Is that correct ?

I thought after I changed DG on Win2003 server, all of PCs should go out through by using new DG's IP(x.x.x.5) because I use DHCP to assign all PCs' IP address.
Am I right ? or DHCP only assigns PCs' IP address, not includes DG's IP ? Please anyone can help me ?....

Wow that was clear as mud.

The Gateway would be your routers address in most cases.
DNS servers would be your ISP's DNS servers unless your server is a Domain Controller/DNS server.

You will also have to disable any other DHCP servers on the network.

 

...well,..after i changed my DG (after changing the ip of my router) it normally takes a while for the networked PCs to correct the change. you can do it manually if you want...

In the DHCP Server properties, you can force the new info to the clients. The default is to update DNS, etc only when the client requests it

 

DHCP works via a lease system. A client is leased an IP configuration for a period. This is commonly a matter of days. The client will only go back to the DHCP server half way through the lease period, unless it is rebooted. Therefore, a change at the DHCP server can take hours if not days to migrate out to all the client PCs.

Therefore if you make an important change at the server you will need to force all the PCs to renegotiate their DHCP leases and thereby pick up the new settings. You can do this by rebooting the PCs or running the command:

Code:

ipconfig /renew
