Domino - NOTES.INI file

There are three ways to edit NOTES.INI settings:

•     Open the NOTES.INI file and edit it. The procedure for doing this depends on your client's or server's operating system and the text editor you use.
•     Create a Configuration Settings document and edit its settings. Using a Configuration Settings document, you can add and modify many NOTES.INI settings at a time. However, there are a number of settings that you cannot set in the Configuration Settings document. Also, because a Configuration Settings document applies only to Domino servers, you cannot use it to modify a Notes client's NOTES.INI file.
•     Use the Set Configuration server command.

Because directly editing the NOTES.INI file is unsafe, it's best to use a Configuration Settings document to modify server settings.
