Failed to scan to SMB after shutting down the computer - Kyocera Ecosys fs-6530 MFP

[Yazan.Lahawani]

Hello everyone My problem with the scanner is that all the configuration are correct and the scanner works fine but once i shutdown the computer and turn it on again it doesn't work again until i restart the computer it will work again.

so shutdown turn on restart solve it, even if i restart the computer 50 times it keeps working until shutdown.

I'm running windows 11, please i need help if anybody faced this

Hostname or IP address?

Hostname or IP address?

Tried both, same thing.

Tried both, same thing.

Any antivirus program?

what the failure code?

No antivirus installed, even the windows defender is turned off.

Error code 2101 but it dissappear after restarting the computer.

I'm not familar with this particular model but I just did a quick goole search and it appears like they first came on the market in 2012. What verison SMB is it trying to negotiate? SMB v.1 will no longer work. Is the firmware up to date?

Is it just one computer.Have you tried scanning to your laptop or another computer?Maybe you have a problem with the switch and it is turning off the port it is using.

Billy has a point that this may be only a SMB1 device, and that has to be enabled on Win11, but if it has worked sometimes then perhaps it is something different.

The only way to know for sure is to Wireshark capture at the MFP to be certain which version of SMB this device is using. You could Wireshark from the laptop when it is working, but you may not see much when it doesn't work depending on the configuration.

The error would most likely point to failed SHARE resolution due to wrong port number, like using port 139 and getting sketchy NetBIOS name/share resolution on the LAN. If you are trying IP address instead then sharename resolution still needs this or DNS so simply trying IP is sometimes insufficient.

Not only must IP address be connected to, but filesystem connection via sharename is also required (DFS hook)

Here are the things you need to find out:
Can you PING the MFP when it is not working.
What is the SMB port number set on the MFP - Port 139 is NetBIOS name res (BAD), Port 445 is DNS (GOOD)
How is laptop connected (Wireless?DHCP?)
How is MFP IP set (Static, DHCP reserved? DHCP NO-RES?)
What is DNS Primary set to? (SOHO router IP?)

You want to use port 445, hostnames for path, and have a good local DNS source which the MFP is connected to.

I've done this on Wireshark and it was very informative. The SMB negoation from the PC to the copier starts with the highest version and works it way down until they they find a version that both can agree on. It may have been you that had me to do this. Can't remember but it was interesting.

Seems more like an OS bug to me - it should at all times either handle the SMB connection from the MFP or refuse it. SMB v1 needs to be enabled manually in windows including safety concerns at certain enviroments.

SMB1 now disabled by default for Windows 11 Home Insiders builds - Microsoft Tech Community

I'm not really into kyo but I assume that "scan-to-ftp" might be a good backup plan.

Yep you did a good job, and SMB messages in Wireshark are very readable so it can help. Subtle changes in configuration changes the way SMB behaves beyond the version negotiation, mainly in user authorization and set-up of the actual file transfer session.

OP...another tip would be to DISABLE NetBIOS on the MFP. Below is a sample of how that can mess up your session:





Attached is a photo of an SMB1 test (c.2016) using port 445 and using IP address for destination. Enabling NetBIOS when using port 445 caused an issue by bringing a NetBIOS Name Service request
in the equation.

On the left, NetBIOS is NOT enabled(on MFP) and the machine uses the Domain\User correctly and is successful at authorization. No NetBIOS packets are sent.

On the right NetBIOS IS enabled and the machine has trouble with Domain\User, first tries no Domain then later tries the default NBT workgroup KM-Netprinters (default workgroup on MFP) always failing to connect because it's forced into NBT for authorization. NetBIOS Name Service is engaged for auth. but has no support on the network.

In this case, there is no DNS query (since IP is known).
