windows 10 computer trying to connect to computer using LANMAN

edit

Hello, I've been capturing some packets on my LAN. All the computers on the LAN are on a windows domain and are all connected to the domain. Strange I've found this computer trying to connect to another computer via SMB2 and when I follow the TCP Stream the details state the following. "PC NETWORK PROGRAM 1.0..LANMAN1.0..Windows for Workgroups 3.1a..LM1.2X002..LANMAN2.1..NT LM 0.12..SMB 2.002..SMB 2.???" I'm not sure why this computer would try to connect to another computer on the domain, they are both workstations and not sharing any files or folders. Could someone explain this to me.

Thank you.
