If you are a Notes Domino Administrator and need to manage databases on a R5 server en-masse (i.e. sign, set ACLs, etc.), then you are in a slight dilemma if you do not already have Manager access to them or do not yet have the R5 Domino Admin client locally installed on the server. You won't be able to "power-through" the tedious job like you used to when you were using the "File - Tools - Admin..." option in the old R4 Notes client.
Now in R5, the Domino server is not by default installed with any Notes clients (except nlnotes.exe). You could launch nlnotes (stored in the Domino server program directory) using the "adminonly" switch (as in nlnotes.exe adminonly) but it's lame. The Domino Admin client starts BUT no files appear in the "Files" tool/pane to manage - what's with that ?!?!?
A safe workaround is to install the R5 Domino Admin client's program and data directories on your R5 Domino server but in a separate file folder than the server's. Do not bother doing a Notes first-time setup but rather change all Domino Admin client launch/shortcuts to reference the server's Notes.ini file.
The Domino Admin client launches using the server's Notes ID, names.nsf, Data dir, etc. Once started just switch "Server:" to "Local" and bam...you're powering through all databases on server with Manager access. Oh yeah boy !!!
Doing it this way prevents Location docs from being inadvertently added to your server's public address book, allows you to use the Notes client UI to affect server's Notes.ini settings, sign DBs and agents with the server's ID, and mass-set ACLs.
Delete the Domino Admim client's notes.ini installed "stub" from LotusNotes folder so there is now chance of being able to launch it and invoke first-time setup.
