DNS not resolving to new machines on network after increasing DHCP pool size

Hello,

I am having a very strange issue with connecting new machines to reach the internet.

We have a ASA 5505 which the previous tech configured the DHCP pool to 192.168.1.60 - 192.168.1.110

We ended up reaching our limit which I changed it to: 192.168.1.60 - 192.168.187

Then next day when I arrived to work, our DC was hung from windows updates. Once we got everything back up, every computer currently on the network can reach the internet/VPN tunnels etc. So (continuing with my day) I created a new server in a VM (Hyper-V)

I can ping everything internally (even the router) 192.168.1.1, but I cannot resolve DNS. I have configured a static IP, tried Dynamic IP.

I have looked for any ACL indicating to block outside the range of the old DHCP pool but no luck.

On my local maching I can ping the DNS addresses, but just not on the new server.

Can anyone point me in the right direction to where to look for this issue?

I ended up figuring out what the issue was.

Since it was in a Hyper-V VM. the hosting server had to be updated to SP1.

Once completed, and rebooted. The VM in question got an IP address.
