OK, I did that once, but then I had the Problem, if a  PC get's a new IP and I added manually his A Record: : "FAILD: Has an address record but no DHCID, not mine."

Any Idea how I can get rid of this?

The server will do another ddns update when it renews the lease if it finds that there isn't already a dns entry. But no way I know of to get the server to do it on demand.

You could write a simple script to do a series of nsupdate commands for all your missing entries, I suppose.
