Hi Joseph, 

It is not really something that Grase is currently designed to do. 
But you could (if you are brave) edit the functions file in /etc/chilli/

Around about line 55 

Replace 

HS_DNS1=${HS_DNS1:-$HS_DNS}
HS_DNS1=${HS_DNS1:-$(grep '^nameserver' /etc/resolv.conf | head -n1 | awk '{print $2}’)}

with 

HS_DNS1=‘192.168.2.2'
HS_DNS2=‘192.168.2.2'

In fact if you just add the last two lines and then just put a # in front of the existing ones then that will work too. 


I am no Windows guru and so there is no guarantee that the DNS resolution alone will be all that you need - but it may work - or at least get you closer to a solution. 
However you will also need to make Grase hand out IP’s in the same network at your DC. 
You can set the LAN IP address in Grase web admin - Network Settings 
and you will need to set the DHCP Start and End in Grase web admin - CovaChilli Settings so as to avoid IP address conflicts. 


I have to say - I am not sure what you are doing is the best thing for what you need - but I understand that sometimes you just have to make something work with minimal investment.

In some cases, I want some computers to have connectivity at specific times of the day. but now, I have failed to adapt this server to my network. when ever i try to deactivate DHCP on my DC, some machines cant log on to the domain.
