Multi OS Network - Master Browser issue

Hello

After a lot of reading lots and lots of forums regarding this issue, trying A LOT of different "solutions", I haven't been able to fix the master browser issue between vista and leopard (not being able to see all the devices connected to my network in Finder -> Shared)....

I know these matters are over debated in this forum and throughout the internet, therefor I apologize creating a new thread about it... but I'm kind of desperate because I really need to make my home network work!

Currently I have 2 XP laptops, 2 Vista laptops, 1 MacBook (Snow Leopard), 1 Popcorn Hour A-110 and 1 Iomega Home Multimedia Network Hard Drive all connected to my D-Link 655 router.

Since I have no desktop computer that could stay on the whole to serve as a master browser, I really don't know how to solve this issue....

I've tried changing the registry values of both Vista laptops so they don't participate the election for the network master browser assignment -> Does NOT work...

I've tried changing the values in my MacBook's smb.conf so it always be elected the master browser -> Does NOT work....

If my PCH A-110 is assigned the master browser, my MacBook will se all the devices in Finder... but I can't leave it on all the time -> A lot o energy consumption and overheating issues...

Iomega's Home Media Network Hard Drive does not seem to win any master browser elections. If I could force it to become the master browser, it would solve my problem since it's always on... But I do not know if it's possible of not...

I've tried turning off all network devices and laptops, and turning them on separately in every possible order, with every possible settings as stated above. My MacBook can only show all the devices in finder when a XP laptop or the PCH A-110 is the master browser.

I'm familiar with the COMMAND + K command, but I just love the Finder -> Shared feature since it's a lot more practical....

With all these tests I just described, I ran the "nmblookup -M -- -." and "smbclient -U% -L localhost" commands in Terminal (MacBook) and the "browstat status" command in CMD.EXE (Vista and XP laptops)... Sometimes, my MacBook can't locate the master browser even if there are no Vista laptops connected...

Is there any FUNCTIONAL solution for this issue?

I would appreciate SO MUCH if someone helped me with this....

Never the less, thank you for reading and sorry about the long post... but this problem is really starting to piss me off....

By the way, I'm from Portugal, so... sorry about my english...

Thanks again,
Pedro
