Ubuntu: Duplicate Icons For Network Devices (Port 139/445 Issue?)



Question:

Previous Environment: Mixed network Windows XP, Windows 10, Windows 7, Ubuntu 17.04 Laptop, Ubuntu 17.04 Server. Samba installed and configured (very basic smb.conf) on both Ubuntu devices. Able to view and access all networked computers and shares just fine.

Updated Environment: Same as before with exception of upgrade server to Lubuntu 17.10 (used Lubuntu because server is old and needed "smaller" OS) and laptop to Ubuntu 17.10. Samba installed and configured (very basic smb.conf) on both the Ubuntu device and Lubuntu device. Able to view and access all networked computers and shares just fine, EXCEPT FOR THE FOLLOWING:

The Ubuntu and Lubuntu show duplicate icons for the same networked device. For example, two computer icons appear for both Ubuntu and Lubuntu devices on the Ubuntu and Lubuntu computers.

Screen Shot--Note Duplicate Devices--SATC855 is laptop, DIM4550 is server

Note that Windows devices all show up in the Ubuntu/Lubuntu computers as single icons, and the Ubuntu/Lubuntu devices show up in the Windows computers as single icons.

I thought this might be related to the fact that sharing can use ports 139 and 445 so in firewall I blocked port 445. This did not work--it only caused devices to NOT appear in the network.

I looked at the properties of the duplicate icons and for the same device.

One icon's properties:

network:///

smb://COMPUTERNAME.local:445/

dnssd-domain-COMPUTERNAME._smb.tcp

The other icon's properties:

network:///

smb://COMPUTERNAME/

smb_server_COMPUTERNAME

Opening either access the same shared folders on the single computer.

I'm confused. Why am I getting duplicate icons? How do I avoid this so a single icon per device shows up as expected?
