Windows 7: Network browsing is dog slow

I have about 8 computers on my network and a variety of other network appliances (dvd players, ect...). Going to the network part of Windows Explorer takes forever to resolve all the machines on my network (2.5 minutes).



I have a freenas box on my network. Originally i had it setup to be the master browswer. Thought it was the problem. So i turned it off and watched which machine would take over. It ended up being a windows 7 virtual machine i had and it was still slow. So i turned off the computer browser service and my Windows 2008 R2 box took over which is exactly what i wanted (thought it would be faster)...but alas its still slow.

Why would it take so long for my computer to communicate with the master browser computer on my workgroup and find out what computers are on my network? I don't want to bother with the headache and the resource drain active directory brings into the picture.

Any help would be appreciated.

thanks...
I'm not a low level wonk that messes with wireshark or anything like that very often.
