I have migrated the DHCP role from an SBS 2008 server to a Win 2008 R2 Ent. server and clients are now getting ip from the new server.

I have checked the firewall on the server and dhcp is Enabled.   What could I be missing?

Are they connected and working?  If so, are they just getting the same internal IP as they had before?  

Go to the new server, DHCP section, and see if clients are listed there.

The question states they are receiving an IP address, but the title does not. Which is it?

Is the new DHCP server activated and authorized within Active Directory? It needs to be in order to hand-out IP addresses on the LAN.

Clients remember the ip of their dhcp server. As long as it it reachable and they have a valid lease, they don't ask for something else. To force them use the new one you can use "ipconfig /release" and "ipconfig /renew".

I assume your dhcp server is authorized in AD?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

The commonest mistake is to forget to authorise the server  http://technet.microsoft.com/en-us/library/cc759688(v=ws.10).aspx

or activate the scope http://technet.microsoft.com/en-us/library/cc786966(v=WS.10).aspx

I did remember authorize the server.
I figured out the issue.  The issue was with switch .  It was pointing to the IP address of the old server.  I had to add another IP address-helper command to point to the other DHCP.
