O.k....I've been getting this error occasionally on a slower link
between two offices and I want to figure out how to fix it.  I'm not
sure if its a PC issue or a Cisco router issue.  I have three networks
across two domains.  All my PC's are located in Domain B but
authenticate to domain A and the servers in question are in Domain A.
The two domains are connected with a Cisco 2821 router and all traffic
from the B side is allowed onto the A side but not the other way
around.  On the B side there are two networks seperated by a point to
point T1.  So it kinda looks like this:


Remote Network (B)    ---  P2P  ---- Local Network (B)   --  Cisco
Router -- Local Network (A)


The connection from the local B to local A works great and the only
time I get a error is this same message when using the wireless system
on local B.  But when copying files from the remote B network up to the
local A network I get this error a lot, especailly from Windows 2000
clients.  The network is definately valid, you can browse it imediately
afterward without a problem.  I do NOT get the error when copying from
remote B to local B which is why I think the timeouts are being caused
by the router.  I've upgraded the routers firmware to the lastest
available and had the same issue.  Any ideas or what I can check next?
