How to fix error: "the specified server cannot perform the requested operation" on SMB share

Question

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

Answer 1

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):

Can you help shed some light on this?
