I have a new Windows 10 tablet that I'm trying to access some network shares with. My host is a debian PC that works fine for sharing three folders to other Windows 10 clients... I don't believe the problem is with the host.
On this new tablet, I'm never prompted for my credentials when trying to access the shared folders. I can browse to the host PC, but I get the "access denied" error message as soon as I double-click on one of the shared folders.
All other clients get prompted for their password.
Followed this thread and now get prompted for login name and password: In Windows 8.1, how to force prompt for credentials when accessing a shared folder?
net use in the power shell, I saw that credentials for the networked drives were already saved. There must have been a previous attempt from the client tablet to connect.
Purging the saved table with
net use * /DELETE results in being prompted for credentials to access shared folders.
Access is still denied, but I think I'll need to start a new question.
