Strange Win-client probs while Linux clients work

I had some problems with profile up- and download where Windows 2K
also showed the message "network name is no longer available".
The connection linux/client <-> linux/server worked here too - but slow.
Even the windows clients worked (most of the time) at a low transfer rate.
Here the problem was a wrong setting of one of the 6 hubs/switches/routers between
the client and the server. You can test your network with ping (lost
packages) and ftp (transfer speed). You should consider testing the 
server with another network interface card (check duplex mode 
and transfer speed, on some systems autodetection did not work). 

Good luck
