Starting With Domino R5, the Notes clients are installed in another directory than the Domino server.
If you need a quick cross certification from the server, simply go to the LotusDomino directory and start NLnotes.exe -- this starts a limited version og the Notes client. Now use file -- Open to try to open another Domino server outside of the domain -- If you need a cross certification you will be asked to accept this cross certificate.
We use this simple method when development servers needs cross certification to the companys actual certificate.
