All Windows Firewall Profiles are OFF --> netsh advf set allp state off

Telnet from remote machine is not working on TCP Port 445.

NETMON shows as follows while accessing network share from remote device.

    Hello Kapil Madaan,

    Thank you for posting in Q&A forum.

    1.Please check if only one domain user or more than one domain user cannot access the shared folder. If it occurs on only one domain user, we can check the permissions (including NTFS permissions and shared permissions) on shared folder.

    2.Please check if the issue occurs on only one domain machine. We can check all the AD ports on this domain client machine and the domain controller and file server.

    3.Please check the issue based on the error message when access the shared folder.
