Workgroup access depends on the order computers are powered up

The following scenario is happening to my workgroup. I have two Windows 10 machines, call them A and B. I power up machine A and log in, and then I power up machine B and log in. A can see and access the shared files on B, and print to B's printer. But machine B does not show up in the workgroup on machine A. If I power up B first and then A, the reverse happens. B can access A, but A cannot see B in the workgroup. This should not be. Both machines should be able to see each other at the same time, and order of power up shouldn't be irrelevant. How can I fix this? Any assistance would be much appreciated.

The first pc on normally become master browser windows doesntlook for pc on the network it asks the master browser what about. The problem is it can take 51 mins for MB to update but in the mean time you can use IP as that bypasses netbios so instead of connecting to \\feed\share connect to \\192.168.1.12\share
