Win 2008 server with DHCP also Netgear DHCP Server running at same time

Hi I wanted to know if my Internet Netgear router that is also running as a DHCP Server, which also has Eth ports on it so when host pcs plug in they obviously can automatically be allocated an address!!!

But if Ive also setup a Win 2008 DC/Dns/Dhcp integrated with SP2 already and being set as 'Reserved Mac Address' within Dhcp, would this affect say my GPO's or the fact that as long as my host pc joins the domain then Im assuming all is ok?

Hi 5q6tdcv4 - Hi thanks for your response now I see where most particular GPO may or may not have come from on an Intermitant basis hence going round in circles due to the setup!!:)

Hi riteheer, No I do not want my 'Netgear' to be the DHCP server although out of the box this is how it is setup or at least when the ISP provider install it for me.

I wish for my test Win 2008 DC/Dns/Dhcp - to be the 'Main server' as all other settings are fine!!

Im not sure how to stop DHCP handing out addresses on the Netgear as Ive already opened up the 'Gui' and currently looking!!

Hi ritehear It looks like it is:

Netgear
VMDG280

I think Ive found it in the GUI under 'LAN IP', there was an option that said 'Dhcp Server Yes or No' So Ive selected No! I may have to reboot the 'Netgear' as the IP Addresses appear to still be there as I would have expected them to disappear or dimm out or something.

I will keep it in mind that you said:

I find it's often easier to run dhcp from the isp router because they tend to go down, and when I put a new one in, I don't have to go in and turn it off again

As I did wonder about this scenario but never did it until now!!

Hi riteheer, Ive just checked again 'No' meant to add addresses Manually so this was not the option!!!

Ive just read:

DHCP Server: Choose Yes to enable the DHCP Server on your gateway and assign IP addresses to computers on your LAN automatically. Choose No to assign IP addresses manually, or if you have another DHCP server on your network. Note: If you disable the DHCP server, you will need to assign your PC a static IP address in order to reconnect to the gateway and enable the DHCP server again.

Not sure where to 'Disable' the server as stated above!!!?

Yes your right by selecting 'No' and rebooting everything should then allow automatically the 'Netgear router' to be 'Disabled' automatically and as I have already a 'Static IP Address' on the server which is currently rebooting, this should hopefully resolve my other GPO issues which have been sending me crazy, one minute work and next not!!!!!!!!

Hi riteheer, So when small to medium businesses run an SBS 2003/2008/2011 server I automatically assumed that everyone setup 'DHCP', but Im assuming this would be down to the IT Professional who set it up although as you say:

and then you will need to release and renew the ip's on the clients. They won't just quit using the current ip's until the lease expires.

'I've set a few smaller networks in my job. 30 machines or less. And having DHCP on the router has another advantage as well, in the event that I need to take the server off line temporarily, all I have to do is reset the dns on the clients to give them internet access while the server is down.'

So really if there are other LANs within a companies network, then Yes DHCP can be used as expected, but when at the edge of the network ie connected directly to the internet your scenario would also be used even though realistically it would be down to that IT Professional for eg!!!!!!!?

Hi riteheer, According to the Netgear router, It is in 'LAN IP' where I select Dhcp Server 'Yes or No', but according to these notes below within the 'GUI' it states:

DHCP Server: Choose Yes to enable the DHCP Server on your gateway and assign IP addresses to computers on your LAN automatically. Choose No to assign IP addresses manually, or if you have another DHCP server on your network. Note: If you disable the DHCP server, you will need to assign your PC a static IP address in order to reconnect to the gateway and enable the DHCP server again.

So Ive took the understanding that setting 'No' automatically 'Disables the Netgear router' anyway...

Not sure how to check this is so though!!

Thanks for your useful comments though!!

Hi riteheer, Yes I did choose 'No' and what I did to test that my DC Server is the master, was to switch on host pc which did not allow me to logon to the internet, but as soon as I switched on my server the host pc allowed internet access.

Yes 'Netgear and Host pc and Server' are on same subnet!! because if server is on a different subnet then internet access will not be allowed nor router access as you say so I agree!!!

Yes your explaination is perfect!!!

appriciated - Job done!!
