os level

This integer value controls what level Samba advertises itself as for browse elections. The value of this parameter determines whether nmbd 8 has a chance of becoming a local master browser for the in the local broadcast area.
Note: By default, Samba will win a local master browsing election over all Microsoft operating systems except a Windows NT 4.0/2000 Domain Controller. This means that a misconfigured Samba host can effectively isolate a subnet for browsing purposes. This parameter is largely auto-configured in the Samba-3 release series and it is seldom necessary to manually override the default setting. Please refer to the chapter on Network Browsing in the Samba-3 HOWTO document for further information regarding the use of this parameter. Note: The maximum value for this parameter is 255. If you use higher values, counting will start at 0!

Example: 65

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
