dhcp and Dynamic DNS -- Multi-Boot OS clients

[Scott Ruckh]

I have some machines that multi-boot between Windows and Linux.  When 
these boxes only booted a single OS the DHCP/DNS servers on the Linux 
behaved as expected.

All the configurations and keys have been set up to allow only the DHCP 
server to send dynamic updates to the DNS server.  This has worked fine 
for a long time when servers were only booting a single OS.

The problem now is when the server boots between the different Operating 
Systems, there are RR conflicts and the DNS records are not dynamically 
updated.

In the messages log is something similar to this:

Mar  5 22:34:21 dhcpserver dhcpd: if multibootclient.example.com. IN TXT 
"00cd2ae121c33f5e99032f48eefaefdc7e" rrset exists and 
multibootclient.example.com. IN A 1.2.3.4  rrset exists delete 
multibootclient.example.com. IN A 1.2.3.4: no such RRset.

I also have seen errors that state:  Can't update forward map.

I read somewhere that there exists a FAQ that addresses this issue, but 
I have yet to find the answer.

Can someone help.

Thanks.
