I just recently added some new hardware to my PC, so installed a fresh copy of Windows 11. I've had my Unraid server running fine for a couple of years, and all other machines on my network can still access the SMB shares as normal, but on this fresh install, I'm getting an error that won't allow me to open the shares, but I can see the server on the network.

 

I've tried using the IP in Explorer, but the same happens. This didn't happen before, is this a bugged Windows 11 install or something?

Do you have network discovery turned on?  Windows settings > network internet > advanced network settings > advanced sharing settings > private networks > click on network discovery

Which Windows 11 version? Note that 24H2 requires SMB signing by default.

Yes, it's turned on and network is set as private. The computer can see the Unraid server, I just can't open it/access the shares.

I just downloaded the Windows 11 image a couple of days ago, and it's fully updated, so it should be the most recent version. How do I look into the SMB signing?

You can disable it in Windows, or to work with Unraid with signing enabled, I found that easiest way is to create a user (with a password set) in Unraid with the same name as the Windows account you are using, it should then ask you for the credentials.

 

If you are using a Microsoft account, it may be better to just create a new Unraid account with a simple username and set a password, then in Windows go to Control Panel - Credential Manager - Windows credentials - Add a Windows Credential and add the correct Unraid server name and credentials:

Legend!! I disabled the SMB signing and can now access the shares! Thanks so much for your help!

Thanks @JorgeB! Finally, disabling SMB signing worked for me on my recent upgrade to W11 24H2 Build 26100.2314

I can't believe I have been struggling with this for months. I wasn't that concerned about it because it was only accessing my Unraid shares from my laptop, which I rarely need to. What is weird is my Unraid (NAS) shows up on my network from my laptop, but I simply could not connect to it. I tried all the stuff Google led me to like enable guest logins in Group Policy, changing registry settings, and a few other options. But what is weird, is it worked at one time. I am not sure when it stopped, but this was the fix. Thank you. I made a user called network and gave it a different password.

You have to understand that Microsoft, in this day and age, does not want you to log onto any server using a 'guest' account. They (and the rest of government and corporate world) consider this to be a security issue! They are actively blocking any means of doing so. Yes, if you find all of the settings in the Windows registry, you can bypass these blocks. But it becomes a wack-a-mole situation because MS will add a new restriction or reset a Windows registry parameter to its default during a Monthly security update with no warning. Your best (and easiest) option is to do what you did, Set up a Share Access user in Unraid and add a Windows Credentials for that user to your Windows Machine. A once-and-done solution!
