Problems from Windows 11 with UNC Access to a Filecluster

Good day,

We have an issue with a file cluster accessed with Windows 11 for a few weeks now.

The file cluster is running on 2 virtual servers on a Windows Server 2019 Datacenter Hyper-V cluster with 4 nodes. The OS of both file servers is Server 2019 and is connected to our IBM SVC with virtual Fibre Channels.

Up to Windows 10 this did not give any problems, but from Windows 11 onwards the following problem arises:

Any access via a UNC path to a share of the Windows 11 file cluster (also replicable with Windows Server 2022) causes Windows Explorer or even the command line to be very sluggish and does not display any icons. This only happens if there is an .EXE file in the root directory of the UNC share.

Example:

\filecluster\share$\notepad.exe -> When called via Explorer, no icons load, trying to display the properties of the exe takes from 5 minutes to several hours.

\filecluster\share$\test\notepad.exe -> If the whole thing is in the subfolder: No problems.

If \filecluster\share$\ is mounted as a network drive (e.g. Z:), no problems occur either.

Windows 10 or other OS also have no problems, only Windows 11.

With a single file server running OS 2019 or OS2022, the problem does NOT occur.

\fileserver\share$\notepad.exe -> No problems.

Anyone else see similar problems?

    Hi,

    Thank you for posting your query.

    Kindly follow the steps provided below to resolve your issue.

    I would like to confirm the following information with you:

    Can we access the file from the problematic client via \IP\files?

    When windows firewall was enabled, will all other devices except for the problematic one can access to the file via \servername\fies?

    Is there any error message when we cannot access the file via \servername\files? If yes, please provide the screenshot for further troubleshooting.

    Meanwhile, please check the Event log via Event Viewer to from both SMB client and SMB server to see if there is any related Event log was triggered when issue occurred, if yes, please provide screenshots of the Event log for further troubleshooting.

    We can access all files, problem is the slow connection from windows 11, no icons displayed and e.g. open the Properties need > 10 minutes on exe-files.

    No errors or warnings in SMB Client or Server.
