Hello,

I have a Windows Server 2008 R2 server running DHCP.  It is not handing out some of the IP's in the scope.  The addresses are not excluded, and they do not show up in the Reservations as BAD_ADDRESS.  They also do not appear to actually be used on the network  right now.  

Thank you for any help you can provide.

How many hosts do you have total to get IP lease ?
and how many IP lease do you have ?

This case will create issue if you have devices equal \ more than maximum DHCP lease count and still there are IP addresses for which DHCP is unable to lease IP addresses

It is quiet possible that in advanced DNS settings tab of dhcp scope "discard A and PTR records when lease expires" check box is selected and causing expired DHCP leases are getting deleted after some time interval from dhcp console causing it looks like that DHCP has not leasing some IP addresses

Expanded the scope, and it is working as expected now.
