DNS forward zone not updating from DHCP

I have my DHCP updating DNS dynamically.  I have a forward zone and reverse lookup zone.  I have properties for both zones set the same.  When DHCP gives an address to a workstation, the DNS reverse lookup zone, gets updated just fine.  Unfortunately the forward zone ( the most important!) is blank.

The dhcp and dns are on a windows 2003 server, it is not part of a domain or AD, nor are our workstations.   Thsnks for your help.

Check that the DNS forward zone allow dynamic updates.
How is the DNS-tab in the DHCP server properties configured? Check the options to "Always update DNS A and PTR records" and "Dynamically update DNS A and PTR records for DHCP clients that do not request updates"

Yes DNS forward zone allows dynamic updates.  Addtionally the DHCP 'dns tab' is set correctly too.  
The funny thing is if I set up the client in the TCP/IP advanced properties to  "REGISTER this connection's addresses in DNS"  The forward zone then gets updated!

So therefore it seems the problem must be with the DHCP server?  Perhaps it is corrupt, what would be the harm in uninstalling and reinstalling the DHCP server.  Mind you that we have 100 addresses leased with it now.   Thanks.

It's normal that the DHCP client handles the update of A-record in forward zone and DHCP server handles registration of PTR record in reverse zone.

When using AD integrated DNS zones, each record object has permissions that nead to allow the record to be updated.
Add the DHCP server (or domain service account used for DHCP server service) into the "DnsUpdateProxy" group to let the DHCP server act on behalf of the client.
