windows 10 22H2 smb issues

Hi all,

I access the share folder created by my NAS. I meet a problem.

while i right-click the share folder, the file explorer would hang several minutes.

And then i catch the packet with wireshark, i find the "tree connect" operation with the invalid path.

for example,

 my share folder: test

 username: test

 the tree connect with invalid path: "/ip/test.zip"

 windows try this invalid path with serveral times.

 Finally, it operates tree connect with correct path "/ip/test", and the file explorer works properly after  that.

Does anyone have ideas?
