If you go to Thunar and ask for the server and it's share explicitly: smb://192.168.1.103/Storage Do you get prompted for credentials or do you get that stupid "Open With" dialog?
I get the "open with" dialog.

Well, I can reproduce part of your symptoms. From Xubuntu 24.10 I ran the smbclient command against my own server. That tells me that the samba client part seems to be working. Then I ran the following command to mount a specific share on that server: xubuntu@xubuntu:~$ gio mount smb://192.168.1.103/srvpublic Authentication Required Enter user and password for share “srvpublic” on “192.168.1.103”: User [xubuntu]: guest Domain [WORKGROUP]: Password: That is the backend command that Thunar should be running when I specify smb://192.168.1.103/srvpublic. It does in fact mount it just the way it should: xubuntu@xubuntu:~$ ls -l /run/user/1000/gvfs total 0 drwx------ 1 xubuntu xubuntu 0 Nov 22 15:58 'smb-share:server=192.168.1.103,share=srvpublic' I can now go into Thunar and view the contents of that share. This tells me that the backend process works as it should. However if I unmount the share, close Thunar, reopen Thunar and specify smb://192.168.1.103/srvpublic I get the "stupid Open With" dialog as if it has no idea what I'm talking about, I truly have no idea what's going on there. Sure sounds like a bug to me.
Huh! Well thanks for taking the time. Maybe I just won't be able to do this for a while. Ironic that it works Windows-Linux, but not Linux-Linux.
Two interesting items: [1] Gigolo, already installed in Xubuntu, can access the server and it's share just fine using Actions > Connect and will display it's contents in Thunar if desired. You can use gigolo to bookmark this connection if you want. [2] There was a bug report submitted to XFCE through redhat that describes this exact situation: How reproducible: Always Steps to Reproduce: 1. Install all Fedora 15 XFCE spin updates and gvfs-smb. 2. Try to navigate to a Windows or other share using SMB. 3. Actual results: Can not navigate to share instead get asked what application to use. It was fixed 13 years ago: https://bugzilla.redhat.com/show_bug.cgi?id=712469 https://bugzilla.xfce.org/show_bug.cgi?id=7774
