Hello,
since updating to Windows 11 24H2, I'm unable to browser a specific NAS.
The connection is established correctly, confirmed by "net use" and can also be mapped using "Map Network Drive" feature.
However when trying to browse and folder on the storage I get the error: "the specified server cannot perform the requested operation"
The storage is using SMBv2 and authentication.
I can access it from other machines without Win11 24H2 without any problem (Other Win11, Win10, Mac OSX)
Already tried to change the RequireSecuritySignature to false, and also enabling the insecure guest logons and disabling the digitally sign communications option, which were suggest for similar issues but without any change in the behavior.
Any help would be appreciated in solving or troubleshooting this.
Thank you in advance

I first saw this on a brand new laptop (running 24H2 at the time of purchase) and tried about ten different things without success. Then an older Windows 11 laptop finally updated and I suddenly saw the same problem on that, whereas things had been working fine on that machine before before. Another laptop still on 23H2 is still working fine, as is a Windows 10 machine.
Two suggestions I haven't fully tried yet are copying all the SMB settings from a working machine to a non-working machine, and checking the entire NAS for (windows) illegal characters in filename. But the NAS only contains backups from windows machines so hard to see how that could have happened.
The strangest thing: the network share works fine from the command prompt. I can even copy files over. But in windows explorer I just get "The specified server cannot perform the requested operation."

Hello,
I recommend checking the SMB service on your client (name: workstation, server). If you've already completed all the suggested steps, consider capturing network logs using tools like Wireshark or Network Monitor to identify any noteworthy activity.

Hello,
I analysed the wireshark but can't figure out what is causing the failure.
Below the screenshot from the non-working connection (from Win11 24H2):
Working connection (from Win Server 2022 21H2):
Can you help shed some light on this?

Same issue, no resolution… I am on 25H2…..After chasing the rabbit, ended in Wonderland….Wonder if Microsoft will land on this issue, pickup and resolve soon? As noted above apparent issue emerged on 24H2
Symptom
Scope: Works on older versions (7, 10, 11). Some PCs sill in use on LAN. Win 11 version 24H2 fails
Troubleshooting: Amongst many other things, tried SMB version variations, Connecting without Hello PIN, flushing DNS cache, checking start up settings, restarting a million times.
At a loss and handicapped without access to NAS from this new windows platform
Any ideas?
