My user have several Windows 2012 servers and Windows 7 VMs. He create a NTFS share volume and found that he can mapped and connect on Windows 2012 server but can't connect on Windows 7. He use the same domain name login to both server and Win7. On Windows server when map the share drive, it connect immediately but on Windows 7 it keep on ask the login name and password. Even he try use the same domain user name to login but still can't connect. What area can I check and solve this issue? Do we need to edit anything about SMB on Windows 7?
