Dynamic Update Fails on Upper Case Host Name

[George L. Sexton]

I've set up Dynamic Updates through my DHCP server, and Bind 9.3

It's mostly working. I have one problem child. The host name offered via
DHCP is MSS_1D34B7. DHCPD won't create the entries.

I've tried removing the DHCP lease, and the entries from the named zone
files and the dynamic update still fails. Grasping at straws, I'm
wondering if the issue might be related to the case of the host name.

Here's an extract of the log file:
