I figured out the answer (actually, I found the answer on another page, Canonical Ubuntu Server docs https://ubuntu.com/server/docs/samba-file-server ): restart both the smbd and nmbd with the command:
systemctl restart smbd.service nmbd.service

How to troubleshoot? My linux server is pingable from my windows laptop. The ss -pant | sort -k 6 command clearly shows that smbd is listening on ports TCP 445 and 139 on both IPv4 and IPv6. I have nmbd running as well, but it’s listening on UDP ports. 137 and 138. I looked at iptables and I see:
root@jeffs-desktop:/etc/samba# iptables -L -n | fgrep -i udp
ufw-skip-to-policy-input udp — 0.0.0.0/0 0.0.0.0/0 udp dpt:137

I don’t know how to find what is the Samba server’s IP address on my PC.
