Thank you for the information — this is very useful, especially the whiteboard tool.
However, I’m confused by the first link, which does not contain any mention of “stopping new connections without shutting down existing connections” — I don’t find anything similar in the text, only a generic description of stopping and starting “a network service”. No specific instructions for this situation (eg. which specific service(s) to stop, while leaving existing user sessions running). There is nothing in this text that appears to specifically apply to my question.
I’m wondering if the section you’re referring to with that URL doesn’t exist — indeed, the section at the end of your URL, 7.3, isn’t present in the document, and my browser shows the URL rewritten to https://knowledgebase.nomachine.com/DT11R00178#8.3 when I click your link. So I may not be reading what you intended?
