December 16, 20241 yr Hello, Windows 11 23H2 OS Build 22635.4655 Logged in using Microsoft account. I just cant seem to connect from explorer to my unraid server. I can ping it, but port 445 is not open. I am so frustrated that I am hoping someone can help me narrow and organize this troubleshooting process. I am unable to connect using a laptop or my desktop. So two different computers.

December 16, 20241 yr Solution See the December 4, 2025 EDIT in the first post of this thread: https://forums.unraid.net/topic/110580-security-is-not-a-dirty-word-unraid-windows-1011-smb-setup/#findComment-1009109 You probably need to make sure that Unraid will use SMB signing if required by the client by adding the code required to the Samba Extras. EDIT: Sorry, I thought you were on 24H2 rather than 23H2... Edited December 16, 20241 yr by Frank1940
December 16, 20241 yr Just to check something have you made sure the share you want to be accessed is exported at the Unraid level?
December 18, 20241 yr Author The answer was SMB signing thank you! Check this out, my RMM software shows my device on Windows 11 24H2 When using "Winver" command it shows Version 23H2. No idea why Action1 shows my device as Win 11 24H2 and Winver shows different but I did reboot and ran commands again with same results.
