After disabled SMB v1 on windows server and/or windows 7, 10 etc. (using this article: https://support.microsoft.com/en-us/help/2696547/how-to-enable-and-disable-smbv1-smbv2-and-smbv3-in-...),
- I cannot SCAN from network multifunctioned copier machine (for example the model: Kyocera FS-6530MFP).
- NAS devices (for example, model QNAP TS-669 pro) frequently disconnected from domain controller.
- lost simple file sharing between windows XP and/or windows server, windows 7.
Once i enabled the SMB v1, everything works fine!
NOTE: if anyone has solution for the SCAN issue, which is my first point, will be glad.
