An employee that is using his own computer that is not joined to AD needs to access two domain shares, H: and U:.
All the permissions for both the folder on the server and the share itself are configured the same on both shares. When he logs in on an A.D joined PC the mounting is successful but on his PC he can only access one of them.
What should I check to troubleshoot the configuration?
I ensured the permissions are set up correctly. I ensured it is machine-based by trying to perform the same task on other non-AD machine, successfully.
