It is possible to get interactive access to Domino server consoles without having launching the full blown R5 Administration client.
Code
You can call up the old R4 style "Remote Server Console" window from the standard R5 client by way of a smart icon. This can be much quicker (and less resource intensive) then having to load the Admin client.
Create a new smart icon (File -> Preferences -> Smart Icon settings) and paste the following @Command into the formula window:
@Command([AdminRemoteConsole])
Save, close, click on the new icon you created and can now access any server console just you like you used to in the R4 server administration panel.
