...
i have a folder on the Server called Private.
I would like to restrict access to the Private folder to Me (Bob) only.
I want to be able to access the file when I go to My-PC OR the Server and login under BoB, so that only I can have access to the private file.
...
Is this possible or do I need a domain server? I believe I had this setup under Windows 7 (it might have been using homegroups) , but can't figure out how to do it under windows 10.
I'm not an expert on this, but from where I'm standing this looks like the very same problem I had. And I think it doesn't really matter if you're on win10 or win7.
I think you have to follow my instructions (share and then restrict under Security),
BUT and this is VERY important (and might be almost too obvious as well),
You have to make sure you that
each user logs on to the server's network share with their OWN Logon Credentials. (Bob as Bob, Jane as Jane etc).
Your problem I suspect is, you may have used Bob's credentials to log on
under Jane and Admin users, and saved the logon.
If this is the case, it would still logon as Bob automatically, without you even noticing > which would lead to the shares being available..
To avoid this, you need to "forget" all logons, so it will ask you next time which one to use.
(start -> Control Panel -> User Accounts and Family Safety -> Credential Manager > Windows Credentials)
Let me know if this helps!
