Yes, as Glen says, defining a static assignment does not "reserve" the address out of any dynamic pools it may be in. This is a common issue with admins used to the Microsoft way of doing things. The ISC server does have an equivalent of the Microsoft way - you can "reserve" a lease to a specific client by adding the flag "reserved;" to the lease record - you either have to stop the server and edit the leases file, or use OMSHELL, to do this.

You need to look at what problem was causing this. If a client asks for an address, it should not be given one that is in use - provided the server is properly configured. There are however some client config issues that can cause problems.

Which one ? The one you asked about (which has been answered - don't have an address that is both in a dynamic range and a static assignment) or the one that is causing the underlying problem ?
