“Logon failure: The user has not been granted the requested logon type at t

I’m getting an error trying to access 192.168.168.9 from 192.168.168.21. The error is “Logon failure: The user has not been granted the requested logon type at this computer.”

I can access 192.168.168.9 from 192.168.168.7 without any errors.

I have done this:
On the remote computer, select
Administrative Tools>Local Security Settings>Local Policies>User Rights Assignment, right-click on Access this computer from the network>Properties>Add Users or Groups, add everyone

In Deny access to this computer from the network
All I have is Guest

I have run Malwarebytes.

What else could be causing this?

Win7 Professional 32bit

Thank you,
