  • What subnet are you using for the static addresses?  Are these machines all in the same location - so that they can all be on the same subnet?

    For your internal network, I suggest you use 192.168.0.0 network with 255.255.0.0 subnet mask.  That will give you 65536 addresses to use.  The tricky part is during the transition.  If this range overlaps with what you're currently using for IP addresses, then you could add the static address range as an excluded range in your DHCP scope.  It should then be easy enough to configure the machines to use DHCP (don't forget to assign their DNS and Default Gateway in the DHCP scope), and all should be fine during that process.  For your servers, or any other devices you want keeping their specific addresses, you could use IP Address Leases in DHCP, or you could just make sure that their address remains in an excluded range.  But make sure you configure their subnet mask to match the one that the rest of the network is on.

    Here's a good article on IPv4 addressing:http://www.arrowmail.co.uk/articles/iprange.aspx

    Best of luck,
