Is it possible to clear a Windows LMB cache?

[David Wuertele]

I have a test lan with a bunch of B, M, P, and H hosts on it (each
configured with DHCP).  There is no DMB, so I expect that P hosts will
not be browseable.

I find that the LMB (a windows XP pro box) has somehow discovered the
P hosts!  I don't know how this is possible, and I'd like to capture
it.

But I need to clean out the LMB's browse list.  Is this possible?

Thanks,
Dave
