I had DNS trouble which was causing delays for Open Directory users logging in from the GUI on their macs.

I've fixed the DNS problems and the delay still remains.

Is there a way to restart, or start/stop, the Open Directory service (or just the Kerberos part) without restarting the server?

You need to check status of your OD using changeip command.

$ sudo changeip -checkhostname

If it reports any problem, backup your OD using Server Admin and follow the result from the command above

To stop/start Open Directory:

sudo launchctl unload /System/Library/LaunchDaemons/org.openldap.slapd.plist
sudo launchctl load /System/Library/LaunchDaemons/org.openldap.slapd.plist

To stop/start Kerberos:

sudo launchctl unload /System/Library/LaunchDaemons/
sudo launchctl unload /System/Library/LaunchDaemons/
sudo launchctl load /System/Library/LaunchDaemons/
sudo launchctl load /System/Library/LaunchDaemons/

Note these are 10.6.x specific commands. They're slightly different for versions above and below.
