Find out who is smb browse master

Hy, i have a netgear nas (debian) which i like to have as smb browse master. But i have the suspicion that the windows 7 notebook grab this role.

How can i figure out who is actualy the brwose master?

The proble is that the samsung blue ray player dosent find the nas storrage.

Is it possible that i have more then one machine in network that takes the browse master role?

My smb.conf

[global]
 browseable = 1
 hostname lookups = 1
 os level = 255
 wins support = Yes
 workgroup = WORKGROUP
 domain master = Yes
 dns proxy = Yes
 preferred master = Yes
 local master = Yes 
 hostname lookups = 1
 dos charset = CP437

Solution

Use nbtstat to find out the computer which is the browsing master. Syntax: nbtstat -a COMPUTER-NAME. The output should contain something like MSBROWSE

Sadly, you have to do this for every single computer in your network.

To view all computers in your current domain, use net view. To view a list of existing domains in your network, use net use /domain.
