Hey everyone,
I'm looking for some advice after upgrading my workstation to Windows 11 24H2. Up until now, I've been staying on 23H2, but I've heard I need to move to the latest version as it's becoming standard. I have three servers at home running Server 2019 STD: Server 1 is my main server, Server 2 is a backup, and Server 3 is a vault. Only I have access to these servers, and they all have just one user account for shared access.
The issue began when I upgraded to 24H2: my workstation was able to access network shares without any problems on 23H2, but now I can't access the folders due to errors regarding NTLM being disabled. Before the upgrade, I was able to map network drives using my username and password normally. I've tried disconnecting the network drives and following a bunch of guides, but still can't reconnect. I've read some tips about enabling Guest logins, but I've disabled those from the start. I even restored my backup of 23H2 because I can't take downtime during the work week, but it seems nothing works with 24H2. I also plan to try a clean install of 24H2 on another laptop, but I need to find a solution for my workstation.
Has anyone else faced this issue, or does anyone know why I'm having trouble accessing these password-protected network shares in 24H2?

One thing worth checking is the local security policy settings for 'Network security: LAN Manager authentication level.' You need to ensure that all devices are set to the same value. Ideally, you should set it to 'Send NTLMv2 response only. Refuse LM & NTLM' to maintain a secure connection. Let me know if that helps!
I think this might be related to NTLM deprecation. Have you made sure that file sharing is enabled on your servers? You might want to check and enable SMB for accessing your file shares properly. It could help with resolving the access issue you're facing after the upgrade!
Yeah, I set up the File server along with the Storage Services before, but I’ll double-check to make sure everything is configured correctly.
Hey! It sounds like the upgrade has messed with your network settings a bit. With 24H2, Guest access to shares is disabled which complicates things if you don’t have Active Directory. You need to make sure that the username and password are identical on every device accessing the shares. Start by unmapping the network drives and then clear any stored credentials in the Windows Credential Manager. After that, remap the drives using the correct credentials that match across all PCs. Also, check to ensure that the network profile on all machines is set to 'Private'. Hope this gets you sorted!
Thanks for the input! Just to confirm, I already checked and all usernames and passwords match on my servers. I also set all profiles to Private. Things still aren’t working, but I’ll follow your advice on the Credential Manager.
Looking into that now. I had read a suggestion to use a less secure setting, so I’ll try your recommendation instead. Thanks!
