Mikrotik RB751U-2HnD, VPN, ping - it's coming, why can't computers be seen on the network?

Question

VPN

There is Mikrotik. VPN is organized on it through Quick Set. (RouterOS v6.18)
Network1. Comp_A is connected to Mikrotik via LAN. On comp_A, in addition to the local network (via DHTsP), a VPN connection to Mikrotik was created. Everything is working. Mikrotik - 192.168.88.1 (VPN 192.168.89.1), Comp_A - 192.168.88.254 (VPN 192.168.89.252)
Network2. Comp_B is connected to the TPLink TL-WR842ND router via LAN. On comp_B, in addition to the local network (via DHTsP), a VPN connection to Mikrotik was created. Everything is working. Interestingly, the Internet goes through the VPN (maybe there is a checkmark "Use the default connection", but this is the tenth question). TPLink - 192.168.1.1, Comp_A - 192.168.1.101 (VPN 192.168.89.254)
Ping from comp_A to comp_B - going (from 192.168.89.252 to 192.168.89.254)
Problem: computers do not see each other, but you need to use file-sharing for 1C accounting to work ... Both computers are Windows 8.1.
Please help someone in the know.

Answer 1

See what traffic is leaving and not coming.
Most likely there are two options:
1. You connect the ball by name - problems with dns or netbios.
Raise normal dns or connect by address.
2. SMB / CIFS traffic is cut by the firewall in the interval or on 8.1.
