The error below occurs during startup only on a number of SBS 2003 servers. It does not occur on ALL of them for some reason.
Event Type: Warning

Description:
The DHCP service has detected that it is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service. This is not a recommended security configuration. Credentials for Dynamic DNS registrations may be configured using the command line “netsh dhcp server set dnscredentials” or via the DHCP Administrative tool.

The solution is pretty self explanatory. Go to a CMD prompt and run the command as follows
Netsh dhcp server set dnscredentials administrator DOMAIN password
Of course substitute your own Netbios domain for DOMAIN above and a password. You could use the administrator account for it if you wish.
Don’t use the administrator account for DNS updates, or your DHCP server will be able to overwrite ANY record on your DNS server.
(And then just changing a printer’s name to match your AD server’s name might ruin your whole domain.)
Use an unprivileged account instead.
