samba - Jan 2005 - local master = no; browse list = no

When I do this in Windows XP :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSetXXX\Services\Browser\Parameters\MaintainServerList
"
     isdomaine master    =    false
     maintainserverlist   =   no

nbtstat -a 192.168.2.135
give these informations :
     MO99           <0x00> Unique  Workstation Service
     BOM            <0x00> Group   Domain Name
     MO99           <0x20> Unique  File Server Service

I want to do the same thing with Samba so I write this :
Local Master = No
browse list = no

But ntbstat -a @IP write these
     SAMBA          <0x00> Unique  Workstation Service
     SAMBA          <0x03> Unique  Messenger Service
     SAMBA          <0x20> Unique  File Server Service
     BOM            <0x00> Group   Domain Name
->    BOM            <0x1e> Group   Potential Master Browser <-

Why ->    BOM            <0x1e> Group   Potential Master Browser <-
?

nmbd : Version 3.0.10-Debian

Thanks.
