File walking issue?

[Jim Salter]

Is there anything noticeably different, network-wise, about this RH box 
from the others?  Different network card, different subnet, etc?  Can 
your other *nix machines sync from this particular Win2K smb filesystem 
fine?  Can the problem child *nix box sync to your other *nix boxen fine?
